Description

  The present invention relates to a training bullet for a bullet-mounted rocket bullet in which a plurality of bullets are releasably mounted on a warhead.

  Conventionally, there has been a training bullet for a bullet-mounted rocket bullet as shown in FIG. 6, for example. A training ammunition 100 shown in FIG. 6 (a) is a propulsion unit loaded with a bullet head 102 equipped with a plurality of ammunitions 101, a ammunition release mechanism 103 composed of pyrotechnics, etc., and a solid propellant 104. A rocket motor 105 is provided. The training bullet 100 has a configuration equivalent to that of a real bullet except that a bullet is loaded on a real bullet and a smoke generating agent 106 is loaded on a bullet 101.

As shown in FIG. 6 (b), the training bullet 100 is loaded into the launcher 200, fired by the operation of the rocket motor 105, and when the predetermined time is reached, the warhead 102 is opened, The operation of the release mechanism 103 releases a plurality of child bullets 101. The released bullets 101 fall while being decelerated by the individual reduction gears 107, and smoke the smoke by activating the fuze along with the landing. In addition, the body of the training bullet 100 decelerates due to a sudden increase in air resistance with the release of the bullet 101 and falls near the landing point of the bullet 101.

  By the way, the conventional training bullets for the bullet-mounted rockets as described above continue to fly when the bullet-release mechanism becomes inoperative, as shown by the dotted line in FIG. The flight distance is greatly increased. For this reason, in consideration of the situation where the secondary bullet release mechanism becomes inoperative, there is a problem that it is necessary to shoot at a sufficiently wide shooting range or to reduce the shooting angle to short range shooting. In addition to this, there is a problem that it takes time to collect the main bullets and training bullets, so it was a problem to solve these problems.

  The present invention has been made paying attention to the above-mentioned conventional problems, and can make a shooting training equivalent to a real bullet after making the landing point close to a normal landing point of a real bullet. The purpose is to provide a training bullet for a bullet-mounted rocket that can easily cope with recovery.

  The training bullet for the bullet-mounted rocket bullet of the present invention has an outer shape and a large size compared to a bullet-shaped rocket bullet equipped with a bullet head and a rocket motor for propulsion loaded with a plurality of bullets. The weight and the center of gravity are almost the same, the simulated warhead corresponding to the actual bullet head, the dummy weight for weight adjustment, and the distance almost equivalent to the shot distance of the actual bullet at the same firing angle as the actual bullet It is set as the structure provided with the rocket motor which generate | occur | produces the total thrust which can fly, and it is a means for solving the conventional subject with the said structure.

  Further, the training bullet for the bullet-mounted rocket of the present invention is characterized in that, as a more preferred embodiment, the simulated warhead is provided with display means that operates during flight or with landing, and further, At least a part of the outer side is formed of a fragile portion that can be broken by an impact load, and the display means includes at least one of a display powder and a display liquid that are discharged to the outside from the broken portion of the fragile portion. Further, the display means includes a light emitter provided outside the simulated warhead and a power source for supplying power to the light emitter.

  According to the training bullet for a bullet-mounted rocket bullet according to claim 1 of the present invention, the interface to the launcher and the handling performance can be made equivalent to a real bullet, and a shooting training that is not different from a real bullet can be performed. The landing point can be set near the normal landing point of the actual bullet. Therefore, even in a relatively narrow range, it is possible to conduct a shooting training equivalent to a real bullet without considering the situation where the flight distance becomes excessive due to a malfunction of the installed equipment, and in a sufficiently wide range, Long-range shooting training can be performed.

  Further, the training bullet for a bullet-mounted rocket bullet according to claim 1 of the present invention does not need to be equipped with a bullet and a bullet discharge mechanism, and the landing point of the training bullet is substantially a real bullet. Because it is the landing point of this, it is possible to obtain a shooting result equivalent to that of a real bullet, and by eliminating the slave bullet and the bullet release mechanism in this way, it is possible to achieve a significant simplification and cost reduction of the structure. In addition, it can be handled and collected easily.

  According to the training bullet for the bullet-mounted rocket bullet according to claim 2 of the present invention, the same effect as that of claim 1 can be obtained, and in addition, during the flight, the display means that operates in conjunction with the landing The visibility after landing or after landing can be improved, and the confirmation and collection work of the shooting result can be made easier.

  According to the training bullet for a bullet-mounted rocket bullet according to claim 3 of the present invention, the same effect as in claim 2 can be obtained, and the fragile portion can be destroyed by an impact caused by appropriate means or landing. Since the display powder and liquid are released, the visibility can be further improved with a simple and inexpensive configuration, and handling is easier than when using pyrotechnics such as smoke generators. It is safe and easy and can eliminate the fear of igniting hay or the like at the landing point.

  According to the training bullet for the bullet-mounted rocket bullet according to claim 4 of the present invention, the same effect as in claim 2 can be obtained, and the luminous body can emit light during flight or after landing. Especially at night, it is possible to improve the visibility during or after landing from during flight, and it is safer and easier to handle than when using pyrotechnics such as smoke generators, The fear of igniting hay and the like at the landing point can be eliminated.

  FIG. 1 is a view for explaining an embodiment of a training bullet for a bullet-mounted rocket bullet according to the present invention. The training bullet A1 shown in FIGS. 1 (a) and 1 (b) has an external appearance with respect to a bullet-mounted rocket (actual bullet) equipped with a bullet head and a propulsion rocket motor on which a plurality of bullets can be released. The shape, size, weight and position of the center of gravity are almost the same, and the simulated bullet head 2 corresponding to the actual bullet head, the dummy weight 3 for weight adjustment, and the actual bullet with the same firing angle as the actual bullet A rocket motor 4 is provided that generates a total thrust that can fly over a distance substantially corresponding to the range of the bullets.

  The simulated warhead 2 is a single unit that eliminates the conventional bullet and the bullet discharge mechanism, and its internal structure is not particularly limited. In addition, a molded body appropriately selected from various materials such as metal, resin, and wood can be loaded so as to obtain the position of the center of gravity, and may be solid or hollow.

  The dummy weight 3 supplements the weight of the solid propellant 5 partially reduced in order to obtain the total thrust that can fly the range of the actual bullet, and its material is not particularly limited. However, in order to make the weight and the center of gravity the same, it is preferable to have a specific gravity equivalent to that of the solid propellant 5. In this embodiment, the dummy weight 3 is made of a material in which the specific gravity is adjusted by mixing metal powder into the resin.

  In this embodiment, the rocket motor 4 is loaded with an internal combustion type solid propellant 5 having an inner hole 5a, and has a well-known rocket nozzle 6 and stabilizing blades 7 on the tail. Here, the illustrated rocket motor 4 corresponds to a real bullet having the same structure as the training bullet 100 shown in FIG. 6, that is, a real bullet rocket motor 105 loaded with an internal combustion type solid propellant 104. Thus, by making the length of the solid propellant 5 in the axial direction and the dimensions of the inner hole 5a the same, the thrust at the time of launch is made equivalent to that of the actual bullet.

  However, although the solid propellant 5 has the same thrust as that of the actual bullet, the diameter of the solid propellant 5 is smaller than that of the actual bullet because the dummy weight 3 is provided outside the rocket motor 4, and the total amount is smaller than that of the actual bullet. Therefore, the amount is an amount that generates a total thrust that can fly a distance substantially corresponding to the range of the actual bullets when fired at the same shooting angle as the actual bullets.

  The training bullet A1 having the above-described configuration employs the simulated bullet head 2 which is a single unit by eliminating the plurality of bullets and the bullet discharge mechanism, and thus has a much simplified structure compared to the conventional one. Thus, manufacturing and handling are easy and the cost can be greatly reduced.

  The training bullet A1 is fired by the operation of the rocket motor 4 after being loaded into the launcher 200, as shown in FIG. At this time, the training bullet A1 has the same external shape, size, weight, and center of gravity as the actual bullet, so the interface to the launcher 200 and handling are equivalent to those of the actual bullet, and as described above, Since the thrust is equivalent to that of a live ammunition, it is possible to carry out a shooting training that is no different from an actual ammunition.

  The training bullet A1 generates a total thrust that allows the rocket motor 4 to fly over a distance substantially equivalent to the firing distance of the actual bullet at the same shooting angle as the actual bullet. As shown in Fig. 4, the flight path (solid line) of the training bullet A1 and the flight path (dotted line) of the actual bullet are landed near the normal landing point of the actual bullet. That is, since the landing point of the training bullet A1 is substantially the landing point of a real bullet, it is possible to obtain a shooting result equivalent to that of a real bullet without using a bullet.

  As a result, even if the training bullet A1 is a relatively narrow launch site, it is possible to perform a firing training equivalent to a real bullet without considering the situation where the flight distance becomes excessive due to a malfunction of the mounted equipment, and a sufficiently wide launch site In this case, it is possible to perform a long-distance shooting training as compared with the conventional case, and moreover, since a plurality of submunitions are not released, the collection operation becomes very easy.

  FIG. 2 is a view for explaining another embodiment of the training bullet for the bullet-mounted rocket bullet according to the present invention. The same parts as those in the previous embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The illustrated training bullet A2 includes a simulated warhead 2 similar to that of the previous embodiment, and also includes a rocket motor 14 loaded with a solid propellant 15 of end face combustion type. The dummy weight 13 is provided between them. This training bullet A2 corresponds to a real bullet in which the solid propellant of the rocket motor is an end face combustion type in particular, and with the above configuration, the thrust at launch is equivalent to that of a real bullet, It flies at a distance that is almost the same as the range of the actual bullets at the same firing angle as the actual bullets.

  Even in the training bullet A2, the same action and effect as in the previous embodiment can be obtained. In addition, as described in the embodiment shown in FIG. 1 and the present embodiment shown in FIG. 2, the solid propellant of the rocket motor in the training bullet is used in the solid propulsion of the actual bullet in order to make the thrust at the time of launching equivalent to the actual bullet. It is desirable to use the same combustion method as the medicine.

  FIG. 3 is a view for explaining still another embodiment of the training bullet for the bullet-mounted rocket bullet according to the present invention. The same parts as those in the previous embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The training bullet A3 shown in FIG. 3 (a) is provided with display means that operates on the simulated warhead 2 along with the landing. In this embodiment, the intermediate portion outside the simulated warhead 2 has an impact load upon landing. And the display means includes a display powder 30 that is accommodated inside the fragile portion 20 and discharged from the ruptured portion of the fragile portion 20 to the outside. .

  The fragile portion 20 is a portion formed thinner than the main body portion of the simulated warhead 2, for example, and has a mechanical strength that can withstand the launch and flight of the training bullet A3. As shown in the figure, the fragile portion 20 can be provided in a plurality of locations as appropriate, and forms at least a part of the outside of the simulated warhead 2 and is destroyed and displayed upon landing. Any material can be used as long as the powder 30 can be discharged.

  Further, a fusible tube 31 that is actuated by landing and a piston 33 that is biased by a spring 32 are accommodated on the tail side of the simulated warhead 2, and the display powder 30 is pushed out by the piston 33. The material of the display powder 30 is not particularly limited, but is preferably one that has as little influence on the environment as possible. For example, lime can be used and it can be appropriately colored.

  The training bullet A3 having the above-described configuration can obtain the same operations and effects as those of the previous embodiments, and, as shown in FIG. The display powder 30 is discharged and dispersed over a wide area. As a result, the visibility after landing is remarkably improved with a simple and inexpensive configuration, and it is possible to make it easier to check and collect the shooting results, as compared to using pyrotechnics such as smoke generators. There are advantages that it is safe and easy to handle and that there is no worry of igniting hay and the like at the landing point.

  FIG. 4 is a view for explaining still another embodiment of the training bullet for the bullet-mounted rocket bullet according to the present invention. The same parts as those in the previous embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The training bullet A4 shown in FIG. 4 (a) is provided with display means that operates during flight on the simulated warhead 2. In this embodiment, an intermediate portion outside the simulated warhead 2 is destroyed by an impact load. The display means 35 includes a display liquid 35 which is formed in the possible fragile portion 20 of a cylindrical shape and is accommodated inside the fragile portion 20 and discharged to the outside from a broken portion of the fragile portion 20.

  The fragile portion 20 is formed with a plurality of open portions 20a at predetermined intervals in the circumferential direction. The open portion 20a is located slightly rearward of the head portion side of the fragile portion 20, and a notch (groove) that breaks when subjected to pressure is formed around the open portion 20a.

  Further, a fusible tube 31 that operates during flight and a piston 33 biased by a spring 32 are accommodated on the tail side of the simulated warhead 2 so that the display liquid 35 is pushed out by the piston 33. . The material of the display liquid 35 is not particularly limited, but for example, appropriately colored spindle oil can be used.

  The training bullet A4 having the above-described configuration can obtain the same operations and effects as the previous embodiments, and the fusible tube 31 is operated during flight to pressurize the display liquid 35 with the piston 33. The open portion 20a of the fragile portion 20 is broken at the notch portion by an impact load due to pressure, and the display liquid 35 is sprayed while flying as shown in FIG. 4B. At this time, since the opening part 20a is located slightly behind the head side of the fragile part 20 as described above, the training bullet A4 does not spray all the display liquid 35 during the flight. The fragile portion 20 is further destroyed by the impact upon landing, and the remaining display liquid 35 is discharged and spread over a wide range.

  As a result, the visibility between flying and after landing is remarkably improved with a simple and inexpensive configuration, making it easier to check and collect the shooting results. Compared with the case of using, there are advantages that handling is safe and easy, and there is no worry of igniting hay or the like at the landing point.

  As described in the embodiment shown in FIGS. 3 and 4, the display means may be any device that operates during flight or after landing. Further, when the simulated warhead 2 has the fragile portion 20, the fragile portion 20 is destroyed by an impact load by an appropriate means such as the fuze 31 and the piston 33 shown in FIG. For the discharge from the broken portion of the portion 20, the display powder 30 of the embodiment shown in FIG. 3, the display liquid 35 of the embodiment shown in FIG. 4, or a mixture of both can be used.

  Further, in the configuration shown in FIG. 4, the portion corresponding to the fragile portion 20 has sufficient strength as the main body portion of the simulated warhead 2, and the portion corresponding to the open portion 20a can be broken by an impact load. The display means may be operated during flight or after landing.

  FIG. 5 is a view for explaining still another embodiment of the training bullet for the bullet-mounted rocket bullet according to the present invention. The same parts as those in the previous embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The illustrated training bullet A5 is provided with a display means that operates in flight or with landing on the simulated bullet head 2. In this embodiment, the training bullet A5 includes a fusible tube 31 that operates during flight or landing, and the display means is simulated. A light emitter 40 provided outside the warhead 2 and a power source 41 for supplying power to the light emitter 40 are provided. The detailed structure of the light emitting body 40 is not particularly limited, but it is desirable that the light emitting body 40 has sufficient strength to withstand impact upon landing, and emits light sufficiently with a small amount of power. For example, a light emitting element such as an LED, They are arranged at predetermined intervals in the circumferential direction and the axial direction of the simulated warhead 2.

  The training bullet A5 having the above-described configuration can obtain the same operations and effects as the previous embodiments, and also lights or flashes the illuminant 40 during flight or with landing. As a result, the visibility is improved during flight and after landing or after landing with a relatively simple and inexpensive configuration, and the visibility at night is remarkably improved, making it easier to check and collect the shooting results. In addition, as in the previous embodiment, it is safer and easier to handle than when using pyrotechnics such as fuming agents, and there is a concern of igniting hay and the like at the landing point. There is an advantage that there is no.

  It should be noted that the detailed configuration of the training bullet for the child bullet-mounted rocket bullet according to the present invention is not limited to the above-described embodiments, and the configuration can be appropriately changed according to the configuration of the actual bullet. In particular, the dummy weight can be mounted on the simulated warhead 2 or distributed in several places.
