DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exercise flying object used for a launching exercise.

[0002]

2. Description of the Related Art In the case of launching a projectile from a launch tube toward a target, if the projectile is a projectile loaded with explosives, it is determined whether the launched projectile has correctly hit the target. The explosive explosion can be easily confirmed by looking at it. However, since explosives are used for projectiles loaded with explosives, there are various restrictions on the use of projectiles loaded with explosives for exercises, for example, for non-actuated projectiles. There is difficulty in terms of safety such as processing. For this reason, in the launching practice, it is common practice to use a flying projectile for an exercise imitating a projectile loaded with explosives.

[0003]

However, on the other hand,
The conventional training projectile can provide a shooting sensation similar to shooting a projectile loaded with explosives, but since there is no explosive that explodes upon collision, it does not destroy itself even if it hits the target, and It is difficult to know the accuracy of the hit. This is particularly noticeable when performing firing exercises for continuous fire.

A so-called smoke projectile in which a detonator is used to detonate a smoke is intended to emit smoke itself, so that the smoke emission duration is long and the amount of smoke emitted is large, so that the collision position can be accurately recognized. It is difficult to do.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to utilize the above-described smoke emitting phenomenon of the smoke emitting projectile to ensure the safety as an exercise projectile while maintaining the collision position. Is to be able to be visually recognized accurately.

[0006]

In order to achieve the above object, the present invention provides a smoke emitting mechanism for indicating the position of a flying object by emitting smoke, and simultaneously operates the smoke emitting mechanism simultaneously with a collision.
Alternatively, it is started immediately after the launch of the flying object and is continued for a relatively short time.

More specifically, according to the first aspect of the present invention, a smoke generating mechanism for generating smoke by burning the marking agent and ejecting the marking smoke to the outside of the shell through the smoke passage, and igniting the marking agent at a predetermined timing. An ignition mechanism for burning is provided, and the ignition mechanism is premised on the structure of an exercise flying object having an ignition mechanism and a smoke generating mechanism configured to ignite the indicator at the time of a collision. The ignition mechanism moves an ignition charge that ignites the indicator charge by ignition combustion, a friction portion that ignites the ignition charge by friction, and receives the acceleration of collision to cause the friction portion to rub against the ignition charge. An operating weight is provided, and a friction hole formed of a tapered hole having a diameter decreasing toward the front is formed through the center of the ignition charge, and the diameter of the operating weight has a diameter toward the front at the center. A tapered friction bar as a reducing friction portion is integrally protruded, and the operating weight moves forward by the acceleration of collision to push the friction bar into the friction hole. To ignite the ignition charge by friction at that time.

According to the second aspect of the present invention, a friction hole is formed through the center of the ignition charge, and a friction line as the friction portion is inserted into the friction hole. Is drawn out of the friction hole, and the ignition charge is ignited by the friction at that time.

According to the third aspect of the present invention, the urging means normally projects into the moving path of the operating weight to stop and hold the operating weight at the retreat end position, while operating by the centrifugal force when the flying object rotates at the time of firing. A stopper is provided for moving the operating weight out of the moving path against the urging force of the urging means so that the weight can move forward.

According to the fourth aspect of the present invention, the smoke passage is opened on the outer peripheral side surface of the shell.

According to the fifth aspect of the present invention, there is provided a shielding means which normally closes the smoke passage and opens the smoke passage after launching the training projectile.

According to a sixth aspect of the present invention, the shielding means is a seal which is broken when the internal pressure of the marking medicine storage chamber or the smoke passage exceeds a predetermined value.

According to a seventh aspect of the present invention, the shielding means is a shutter ring which rotates relative to the shell by inertia force when the flying object rotates at the time of launch to open a smoke passage.

[0014] In the invention according to claim 8, the marking medicine storage chamber and the smoke passage are partitioned by a mesh.

According to a ninth aspect of the present invention, there is provided a medicine paper and a fast-burning wire for transmitting the ignition by the ignition mechanism to the entire marking medicine.

According to a tenth aspect of the present invention, in the exercise flying object according to the second aspect, the shell is divided into a first divided portion having at least a labeling agent and an ignition charge and a second divided portion composed of another portion. It is possible that both divided parts are divided by the firing acceleration of the training projectile, fly integrally and separated by the acceleration of collision, and the friction part is pulled out from the ignition charge by the separation of the two divided parts. I do.

According to the eleventh aspect of the present invention, the smoke passage is connected to the first
The opening is formed on the side of the second divided portion of the divided portion.

According to the twelfth aspect of the present invention, the shell is formed such that a thin portion thinner than the other portion is formed, and the thin portion divides the two split portions.

According to the thirteenth aspect of the present invention, the first and the second
Are connected by a shear pin, and the two split sections are split by shearing due to the firing acceleration of the shear pin.

[0020]

According to the above construction, when the ignition mechanism operates at a predetermined timing, the operation of the ignition mechanism activates the smoke generating mechanism, igniting and burning the indicator medicine, and the combustion of the indicator medicine causes the smoke to pass through the smoke passage. It is squirted out of the shell through. The position of the collision is indicated by the smoke, and the collision can be visually recognized.

Further, since explosives such as a projectile loaded with explosives are not used, it is safe even if the projectile does not emit smoke and is in an inoperative state. Can be secured.

According to the first aspect of the present invention, when the training projectile collides, the ignition mechanism is activated at that time to ignite the indicating drug. For this reason, as in the case of using a projectile loaded with explosives, as soon as the projectile for training collides, smoke will be emitted immediately without intervening with a break, and the location of the collision will be accurately determined by this marking smoke. You can see it.

According to the first aspect of the present invention, in response to the collision, the actuation weight moves so as to cause the friction portion to rub against the igniting charge by receiving the acceleration, and the igniting charge is ignited by the friction with the friction portion. The marking medicine is ignited by the ignition and combustion of the explosive and burns.

According to the first aspect of the present invention, the operating weight advances due to the acceleration of the collision, whereby the friction portion is pushed into the igniting charge, and the igniting charge is ignited by the friction at the time of the pushing. According to the second aspect of the present invention, the friction portion is pulled out of the igniting charge by the acceleration of the collision, and the igniting charge is ignited by the friction at the time of the pulling out.

According to the third aspect of the invention, the stopper always projects into the moving path of the operating weight by the urging force of the urging means, and the operating weight is stopped and held at the retreat end position by this stopper. When the training projectile is launched toward the target, the projectile rotates at the time of its launch, and the stopper moves out of the movement path of the operating weight against the biasing force of the biasing means due to the rotational centrifugal force. Then, the operating weight can move forward. That is, the operating weight is stopped and held at the retreat end position except when the training projectile is fired, and can be advanced for the first time by rotation at the time of firing, so that erroneous smoke operation due to careless advance of the operating weight is reliably prevented. be able to.

According to the fourth aspect of the present invention, the marking smoke is emitted from the smoke passage opened on the outer peripheral side surface of the shell. Therefore, an appropriate opening position of the smoke passage can be obtained.

According to the fifth aspect of the present invention, the smoke passage through which the marking smoke generated by the burning of the marking medicine is ejected from the marking medicine accommodating chamber to the outside of the shell is always closed by the shielding means. Will be opened after launch. In other words, the smoke passage can be closed when it is not necessary to generate smoke due to the burning of the indicator drug, and it is possible to reliably prevent moisture from entering the shell through the smoke passage.

According to the sixth aspect of the present invention, the internal pressure of the marker storage chamber or the smoke passage increases with the ignition and combustion of the marker,
When the pressure exceeds a predetermined value, the seal is broken and the smoke passage is opened. Since the smoke passage is opened at a stroke in this manner, the response of the collision sign due to the smoke squirting from the training flying object is improved, and the sign and the density of the smoke can be increased to provide a clear sign.

In the seventh aspect of the invention, the shutter ring normally closes the smoke passage, but the shutter ring rotates relative to the shell due to the inertial force when the flying object rotates at the time of firing, and the smoke passage is opened. .

According to the eighth aspect of the present invention, since the marker storage chamber is defined by the mesh with respect to the smoke passage, the temperature of the marker at the time of combustion can be reduced by the mesh, and when the combustion temperature increases. The generation of flame can be suppressed, and the smoking operation can be stably performed. In addition, it is possible to prevent a risk that a burning gas or a flame ignites surrounding hay and the like, thereby causing a forest fire or the like.

According to the ninth aspect of the present invention, when the flame ignited by the ignition mechanism ignites a part of the medicine paper, the ignition is transmitted to the whole of the marking medicine by the medicine paper and the fast firing wire. Therefore, it is possible to uniformly and quickly burn the entire labeling drug, thereby improving the responsiveness of smoking.

According to the tenth aspect of the present invention, when the flying object for exercise is fired, the first and second split portions are split by the firing acceleration, and both split portions fly integrally toward the target in the split state. . Thereafter, when the exercise flying object collides, the two divided portions in the above-mentioned divided state are separated by the acceleration at that time. With the separation of the two divided portions, the friction portion is pulled out of the ignition charge, and the ignition charge is ignited by the friction at the time of the pulling out.

According to the eleventh aspect of the present invention, the second part of the first division unit
Smoke for indication gushes from the smoke passage opened to the division side. Therefore, an appropriate opening position of the smoke passage is obtained.

According to the twelfth aspect of the present invention, the shell is divided into thin portions by the acceleration at the time of launch of the training projectile. Further, according to the invention of claim 13, the shear pin is sheared and broken by the acceleration at the time of launching of the flying object for training, and as a result, the two divided portions are divided. According to these inventions, it is easy to obtain a structure in which both of the divided portions are divided when the training projectile is fired.

That is, a bottomed weight sliding hole 21 having a depth from the rear half of the holder 3 to the front-rear middle part of the front half is formed concentrically with the ignition charge housing 18 at the center of the rear end face of the holder 3. , These igniting agent accommodating portion 18 and weight sliding hole 21
Are concentric with the partition wall between them and the friction holes 17 of the ignition charge 16
They are communicated by an insertion hole 22 formed with a larger diameter. A steel operating weight 24 having a predetermined weight is fitted into the weight sliding hole 21 so as to be slidable in the front-rear direction.
At the center of the front end of the operating weight 24, a tapered friction bar 25 as a friction portion whose diameter decreases toward the front is integrally protruded, and the taper angle of the friction bar 25 is set to the friction hole of the ignition charge 16. 17, the maximum diameter is set larger than the minimum diameter of the friction hole 17, and the operating weight 24 is advanced from the retreat end position by the acceleration of the collision, and the front end friction bar 25 is moved. Insertion hole 22
The friction rod 25 rubs the periphery of the ignition charge friction hole 17 to ignite the ignition charge 16 by friction at that time.

The igniter 16 is accommodated in the bottom of the igniter accommodating portion 18 with a space on the opening side (front side) of the igniter 16 when the friction rod 25 rubs the friction hole 17 of the igniter 16. The deflagration of the indicator 9 is prevented by the space in front of the igniter 16.

The igniter 16 is housed in an igniter housing 18 covered with a bottomed cylindrical holder 16a having an opening at the center of the bottom of the front surface. The holder 16a is prevented from jumping forward from the storage portion 18.

Further, a ring groove 3b is formed on the front surface of the holder 3 so as to be cut out concentrically around the igniter accommodating portion 18, and each communication hole 6 is opened at the bottom of the ring groove 3b. That is, the ring groove 3b and the ignition groove accommodation portion 18
Thus, a cylindrical portion 3c is formed between the two, and the cylindrical portion 3c prevents the wire mesh 13 from bending due to a firing impact or a collision impact.

A plurality of slits 24 in the form of a groove extending from the front end to the rear end are formed on the outer peripheral surface of the operating weight 24.
are formed at intervals on the circumference, and when the operating weight 24 advances, the air in the space inside the weight sliding hole 21 before and after the working weight 24 (the opening at the rear end of the weight sliding hole 21 is (Closed by the body 43)
The connection of a allows the working weight 24 to move smoothly.

The insertion hole 2 at the bottom of the weight sliding hole 21
Reference numeral 2 denotes a structure in which when the operating weight 24 moves forward, the operating weight 24 closes and the communication with the communication hole 6 is cut off. I'm going to head.

As shown in FIG. 2, a pair of stopper accommodation holes 27 extending in the radial direction are provided at positions on the outer peripheral surface of the holder 3 where the front and rear positions are the same as the openings of the communication holes 6 but at different circumferential positions. 27 and pin insertion holes 34, 34 are formed to be diametrically opposed to each other. Each of the stopper receiving holes 27 is a stepped through hole having a small diameter portion 27a having a smaller diameter than the other portion at the bottom end. A stopper 28 is slidably fitted into each of the stopper receiving holes 27. ing.
The tip of the stopper 28 is a locking portion 28a having a smaller diameter than the other portions. The locking portion 28a is inserted through the small diameter portion 27a of the stopper housing hole 27 when the stopper 28 moves inward in the radial direction. It protrudes into the weight sliding hole 21.
As shown in FIG. 3, the outer peripheral opening of the stopper housing hole 27 is covered with a tape 29 serving as a spring retainer, and the stopper 28 is biased radially inward between the tape 29 and the back surface of the stopper 28. The spring 30 as a biasing means is contracted.
The stoppers 28 are positioned inward in the radial direction by the urging force of the above, and the engaging portions 28a at the distal ends are protruded into the weight sliding holes 21 which are the moving paths of the operating weights 24. The operation weight 24 is stopped and held at the retreat end position by being locked to the front end face, while the respective stoppers 28 are radially opposed to the urging force of the spring 30 by the centrifugal force when the flying object A1 rotates at the time of firing. Side to move the locking portion 28a into the stopper accommodation hole 27.
The weight slide hole 21 (operating weight 24
Of the working weight 2 by moving the
4 is removed from the restriction by the stopper 28 so as to be able to move forward from the retreat end position.

A pin insertion hole 31 is formed in the outer peripheral surface of the rear half of the holder 3 so as to extend to the weight sliding hole 21. On the other hand, a pin hole 24a is formed on the outer periphery of the operating weight 24 so as to match the pin insertion hole 31 when the operating weight 24 is at the retreat end position.
A resin shear pin 32 is inserted through the pin insertion hole 31 or the pin hole 24a in a state in which the pin 4 is at the retreat end position.
The shear pin 32 is sheared when the operating weight 24 advances due to the acceleration of a collision after the operating weight 24 can be advanced by the movement of the stopper 28.

On the other hand, as shown in FIG. 1, the temporary cap 41 has a hemispherical bottom similar to the cup 7 of the indicator unit 2 and has a cylindrical shape with a bottom open to the rear. The cup 7 or the front half of the holder 3 is accommodated in a substantially close contact state. The rear end of the temporary cap 41 is a small diameter portion 41a in which the outer periphery of the rear end is cut out in a stepped manner.

The body 43 has the same diameter as that of the temporary cap 41 and has the same cylindrical shape with a bottom and is opened forward. The small-diameter portion of the temporary cap 41 has an inner peripheral surface at the front end thereof. 41
a It is screwed to the outer periphery. That is, the temporary cap 41 and the body 43 are integrally connected by screwing with the respective openings abutting each other.

Further, a pin engaging groove 44 in the front-rear direction is formed on the inner peripheral surface of the front end portion of the body 43 so as to correspond to the pin inserting hole 34 on the outer peripheral surface of the holder 3 of the marking medicine unit 2. By inserting a knock pin 45 into the insertion hole 34 and engaging the head of the knock pin 45 with the pin engagement groove 44, the body 43 (shell 1) is fixed to the labeling drug unit 2.

Further, on the outer periphery of the front end portion of the body 43, a smoke outlet 47 is formed corresponding to the outer peripheral side opening of each communication hole 6 in the holder 3 of the marking medicine unit 2. And
The smoke outlet 47 and the communication hole 6 constitute a smoke passage 48 having one end communicating with the indication medicine storage chamber 8 and the other end opening to the outer peripheral side surface of the shell 1. The smoke generated by the combustion of the fuel is blown out of the shell 1 from the labeling medicine storage chamber 8.

Further, the smoke outlet 47 constituting a part of the smoke passage 48 in the body 43 is closed by a rubber seal 49 as a shielding means, and the smoke passage 48 is normally closed by the seal 49. When the internal pressure of the sign storage chamber 8 or the smoke passage 48 leading to the sign accommodating chamber 8 or the smoke passage 48 leading to it becomes higher than a predetermined value due to the smoke emission of the marking medicine 9 after the launching of the flying object A1, the seal 49 is broken and blown out of the shell 1 to reduce the smoke. The passage 48 is opened.

The propellant charge case B has a cylindrical shape with a bottom that holds the body 43 of the flying object A1 at the tip.
A chamber 83 filled with a propellant 82 detonated by a primer 81 is formed in the bottom wall at the rear end, and the chamber 83 flies in the propellant charging case B through gas ejection holes 84, 84,. The body A1 is in communication with the rear end face, and the combustion gas pressure of the propellant 82 is applied to the rear end face of the projectile A1 so that the projectile A
1 is fired.

Next, the operation from the launch of the flying object A1 of the exercise flying object in the above embodiment to the smoke emission accompanying the collision will be described with reference to the process diagram shown in FIG.

Projectile A incorporated into propellant charge case B
When the propellant 1 is loaded in the firing cylinder and the propellant 82 is detonated and burned by the detonator 81, the combustion gas of the propellant 82 blows out into the propellant charging case B through the gas discharge holes 84, 84,. The gas pressure acts on the rear end of the flying object A1 and the flying object A
Advance one. This combustion gas pressure continues to act while the flying object A1 is in the launch cylinder, and the flying object A1 is launched from the launch cylinder by this combustion gas pressure (stroke 1) and flies toward the target.

In the state of launch from this launch tube, the flying object A
1 spins at a high speed of about 10000 rpm, and this rotation generates a centrifugal force. Therefore, the labeling drug unit 2
The stoppers 28 urged by the urging force of the spring 30 at the
Move radially outward against the urging force of 0 (stroke 2),
The engaging portion 28a at the tip of the weight slide hole 21 is immersed in the stopper receiving hole 27, and the weight sliding hole 21 is a moving path of the operating weight 24.
As a result, the operating weight 24 is unlocked at the retreat end position and can be advanced (stroke 3).

Thereafter, when the flying object A1 hits a target or the like,
An inertial force is generated by the impact acceleration of the collision, and the working weight 24 that can be advanced by the inertial force advances while shearing the shear pin 32 (strokes 4 and 5). When the operating weight 24 reaches the forward end position, a tapered rod-like friction bar 25 at the tip thereof is pushed into the friction hole 17 of the igniter 16, and the igniter 16 is ignited by the abrasion friction at this time and burns ( Step 6). The combustion of the ignition charge 16 causes the flame to squirt forward from the ignition charge storage section 18 to ignite the center of the medicine paper 12 in the labeling medicine storage chamber 8 and to ignite the marking medicine 9 from the medicine paper 12, Smoke is generated by the burning of the indicator 9 (step 7).

At this time, since the fast firing wire 11 is wrapped around the medicine bag 10 of the marking medicine 9 in the marking medicine unit 2, the medicine paper 12 is ignited by the flame from the igniting medicine 16, and the flame is applied to the medicine medicine 9. At the same time as the center of the rear end is ignited, it is transmitted to the entire marking medicine 9 by the fast firing wire 11. For this reason, the entire marking medicine 9 can be uniformly and quickly burned, and the responsiveness of the smoking operation can be improved.

In addition, since the labeling medicine storage chamber 8 is divided by the wire net 13 with respect to the smoke passage 48, when the labeling medicine 9 burns,
Due to the cooling effect of the wire net 13, the combustion temperature of the indicator 9 can be reduced. As a result, when the indicator 9 burns at a high temperature, it is possible to suppress the generation of flame without generating smoke, and to stably perform the operation of generating smoke.

In the case of colored smoke, the dye contained in the marking agent 9 is not thermally decomposed due to the cooling effect of the wire net 13, so that a vivid colored smoke can be emitted.

When the internal pressure of the labeling medicine storage chamber 8 or the smoke passage 48 communicating therewith increases due to the combustion and smoking of the labeling medicine 9 and exceeds a predetermined value (stroke 8), the seal 4
9 is destroyed and blown out of the shell 1 and the smoke passage 48
Is released (Step 9). When the smoke passage 48 is opened, the smoke is blown out from the inside of the shell 1 to the outside through the smoke passage 48 and blows out from each of the smoke outlets 47 on the outer peripheral side surface of the shell 1 at a stretch (stroke 10). Is marked. Therefore, by looking at the smoke sign, the collision position can be easily visually recognized from the firing place.

As described above, when the internal pressure of the marking medicine storage chamber 8 or the smoke passage 48 becomes higher than a predetermined value due to the burning of the marking medicine 9, the seal 49 is broken and the smoke passage 48 is opened at a stroke. The response of the smoke sign due to the smoke ejected from the flying object A1 is improved (according to the experiment of the inventor, about 100 milliseconds from the time of the collision). In addition, the density and color of the marking smoke can be increased, so that the collision position can be clearly marked.

In the flying object A1 of this embodiment,
Since explosives such as flying objects loaded with explosives are not used, it is safe even if inoperative by any chance, and the flying object A1
Safety can be ensured.

Further, the ignition mechanism 15 is activated by the acceleration of the collision of the projectile A1 to ignite the indicator 9, so that the collision of the projectile A1 is performed in the same manner as when using a projectile loaded with explosives. At the same time, smoke can be emitted with high response. As a result, even if the flying object A1 hits a target or the like and flies, smoke can be reliably emitted at the acceleration at the time of the collision, which is the first impact, and the collision position can be more accurately recognized.

The operating weight 24 is used for the flying object A.
When the launching state of the flying object A1 is reached, the operation weight 24 is always restricted by the stopper 28 except for the shooting and firing of the flying object A1 because the structure is such that the restriction of the stopper 28 is released by the rotational centrifugal force and the vehicle can move forward. As a result, it is stopped and held at the retracted end position. Therefore, it is possible to reliably prevent the operating weight 24 from inadvertently advancing during the storage or handling of the flying object A1 to operate the ignition mechanism 15 and to ignite the indicator medicine 9 and emit smoke.

Further, since the smoke passage 48 is normally closed by the seal 49 and the communication between the inside and the outside of the shell 1 by the smoke passage 48 is interrupted, moisture, dust and the like enter the shell 1 through the smoke passage 48. As a result, it is possible to reliably prevent the smoke emitting operation of the flying object A1 from being performed properly.

When the flying object A1 does not operate at the time of a collision and becomes an inoperative state as described above, the flying object A1 can be picked up and thrown into a fire such as a bonfire to heat the flying object A1 from the outside. Good. This heating causes the ignition mechanism 15 to operate, and the marking mechanism 9 is burned by the ignition mechanism 15, so that even a non-operating flying object can be safely and easily disposed of.

(Embodiment 2) FIGS. 5 and 6 show Embodiment 2 of the present invention (FIG. 1).
3 are denoted by the same reference numerals and detailed description thereof will be omitted), an ignition mechanism 15 for igniting the indicator 9 and a blocking means for opening and closing the smoke passage 48 will be changed. .

That is, in this embodiment, contrary to the first embodiment, the cup 7, the marker 9, the wire mesh 13 and the like in the marker unit 2 are arranged on the rear side of the holder 3, and basically, It is housed in the body 43. The holder 3 is divided into a front side portion 4 and a rear side portion 5, and an igniting agent storage portion 18 is opened rearward toward the marking agent 9 in the cup 7 on the rear surface of the rear side portion 5. 16 are loaded. An open weight sliding hole 21 is formed in the front surface of the holder 4 and an operating weight 24 is slidably inserted into the weight sliding hole 21. The operating weight 24 is provided with stoppers 28, 28. The stop is restricted to the retreat end position by this.

The friction hole 17 of the igniter 16 is not a tapered hole but a mere small-diameter through-hole. A friction wire 26 made of a copper wire or the like as a friction portion is inserted into the friction hole 17. As shown in FIG. 6, the rear end of the friction wire 26 is fed out from the friction hole 17 of the ignition charge 16 to the rear side and folded, and a friction agent (not shown) is applied to the surface of the folded portion. The folded portion is covered with a sheet-shaped resin cushion 35 in order to prevent the abrasion agent from peeling off due to the shot impact. On the other hand, the front end of the friction wire 26 is inserted through a center hole 36 formed through the operating weight 24, protrudes toward the front surface side, and is fixed to the front surface by welding or the like. Each of the stoppers 28 is rotated by the spin of the flying object A2 at the time of firing.
Moves outward in the radial direction so that the operating weight 24 can move forward.
Is advanced, the friction line 26 is drawn forward from the friction hole 17 of the igniter 16 by the advancing operating weight 24, and the igniter 16 is ignited and burned by the friction between the abradant and the igniter 16 at that time. I try to make it.

A space 37 is formed between the communication passages 6 and the smoke outlet 47 of the body 43 to form a smoke passage 48. In this space portion 37, the smoke outlet 47 of the body 43 is provided.
A shutter ring 52 is disposed as a shielding means for opening and closing the (smoke passage 48).

As shown in FIGS. 7 and 9, a through hole 53 is formed in the outer periphery of the shutter ring 52 at a position corresponding to the smoke outlet 47 of the body 43 in a radial direction.

As shown in FIGS. 7 and 8, on the outer periphery of the shutter ring 52, a front-rear portion 55a extending from the rear end of the ring 52 toward the front side to the middle of the ring, and the front-rear portion 55a A pin locking groove 55 including a circumferential portion 55b extending by a predetermined dimension from the front end toward the circumferential direction of the spinning direction when the flying object A2 is fired, and extends from the rear end of the shutter ring 52 to the front side to the middle portion of the ring. A plurality of bottomed adhesive injection grooves 58 are respectively formed. The inner end of a stop pin 57 inserted into a pin insertion hole 56 penetrating the body 43 is engaged with the circumferential portion 55b of the pin locking groove 55. The shutter ring 52 is rotatable with respect to the body 43 by being relatively moved in the circumferential direction within the circumferential portion 55b of the groove 55, and the stop pin 57 is moved in the front-rear direction at the circumferential portion 55b of the pin locking groove 55. 55a

By injecting and curing the adhesive from the smoke outlet 47 to the adhesive injection groove 58, the shutter ring 52 is fixedly held at the closed position with the adhesive.

In this embodiment, the propellant charge case B
When the flying object A2 is fired by the combustion gas pressure of the propellant 82 and spins at a high speed, the inertial force of its rotation causes the adhesive fixing the shutter ring 52 to the closed position on the body 43 to be sheared and broken. This allows the shutter ring 52 to rotate with respect to the body 43. Subsequently, the shutter ring 52 is rotated to the open position while locking and guiding the stop pin 57 in the pin locking groove 55, and is rotated to the open position.
Matches the smoke outlet 47 of the body 43, and the smoke passage 48 is opened. Basically, the through hole 53 and the smoke outlet 47

4 comes out of the weight sliding hole 21 which is a moving path. As a result, the operating weight 24 is unlocked at the retracted end position and can be advanced.

Thereafter, when the flying object A2 flies toward the target and collides, an inertial force is generated by the acceleration, and the inertial force causes the operating weight 24 to be able to move forward.
Moves forward. With the advance of the operating weight 24, the friction line 26 connected to the operating weight 24 is pulled forward and moves. At this time, the friction line 26 is rubbed in the friction hole 17 of the ignition charge 16, and at this time, The igniting charge 16 is ignited by the frictional friction and burns. The combustion of the igniter 16 causes the flame to be ejected rearward from the igniter container 18 to ignite the marker 9 in the marker container 8 via the medicine paper 12 at the front end thereof. Combustion produces smoke. This smoke is in the above-mentioned open state (or the smoke outlet 47).
Is blown out of the shell 1 through the smoke passage 48 (while the adhesive is blown off when the adhesive is closed), the smoke position indicates the collision position of the flying object A2.

May be weakened by changing the material, shape, or the like. That is, while the combustion gas of the propellant 82 in the propellant charging case B moves the projectile A1 in the launch cylinder, the pressure of the combustion gas causes the seal 49 to move.
Is blown off to open the chimney 47, and is introduced into the shell 1 from the opened chimney 47 (smoke passage 48) to introduce the marking drug 9.
And ignites it, that is, the combustion gas of the propellant 82 is used as an ignition mechanism of the igniter 16.

In this case, since the flame of the igniter 16 ignites and burns the indicator 9 by the combustion gas of the propellant 82, the flying object A1 flies toward the target while emitting smoke immediately after the launch. The collision position can be easily visually recognized by following it.

Further, since the ignition charge 16 is ignited by the propellant gas, the operating weight 24, the stopper 28 and the like are not required in the flying object A1, and the structure of the flying object A1 can be simplified accordingly.

In this case, the propellant gas may be more positively and smoothly introduced into the body 43 and transmitted to the marking medicine 9, so that the above effect can be obtained more reliably.
