Description

Description: Object of the Invention (Industrial application field) The present invention relates to a projectile launching device by a shooter, and more particularly to a device for reducing a reaction force at the time of projectile launching.

(Prior Art) In general, a projectile launching device that launches a projectile such as a small rocket or a target tracking missile by a shooter is configured as shown in FIG. That is, in the figure, reference numeral 11 denotes a launch cylinder for storing the flying object 10 and determining the emission direction of the flying object 10. Usually, a front lid 12 and a rear lid 13 are attached to both ends of the launch cylinder 11 after the flying object 10 is stored. Flying object 10
When a firing command is given, the rocket motor in the rear is ignited and the blast is released backward. This blast hits the inner surface of the launch tube 11 and the rear cover 13 and pushes the entire launch tube 11 rearward. At this time, the rear cover 13 is blown backward. However, since the position of the launching cylinder 11 is fixed by the shooter, the projectile 10 receives hydraulic power forward. Therefore, the flying object 10 slides in the launching cylinder 11, pushes the front cover 12, and is ejected to the outside.

Here, the shooter receives various reaction forces when projectiles are launched. The force includes the force applied to the entire launching cylinder 11 by the ballast suddenly ejected when the rocket motor is ignited, the force applied when the rear cover 13 is blown off, the force applied when the flying object 10 pierces the front cover 12, and the like. If the reaction force becomes greater than a certain level, the burden on the shooter increases.
, And the friction force in the forward direction is increased to offset the rearward blast reaction force. Also, recently, the projectile 10 and the launch tube 11 are connected by a wire or the like, and the projectile 10
A method of canceling the blast reaction force by giving a forward force to the launching cylinder 11 by launching the blast gun has been considered.

(Problems to be Solved by the Invention) As described above, in the conventional projectile launching apparatus, the force due to the movement of the projectile is directly applied to the launch cylinder as the force for canceling the blast reaction force. The reaction force canceling force increases or decreases due to the influence of the unevenness of the outer shape (wings, joints of the housing, screw heads, etc.). If the reaction force canceling force increases or decreases in this way, it becomes difficult to predict the shooting cylinder holding force of the shooter, and it becomes impossible to maintain the shooting cylinder in a desired direction when projectiles are fired.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a flying object launching device capable of obtaining a stable reaction force and a canceling force thereof.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, a flying object launching device according to the present invention supports a front inner surface launching cylinder portion that supports a front portion of a flying object and a rear portion. A rear inner firing cylinder portion, the front inner firing cylinder portion is composed of a plurality of block pieces, and an inner firing cylinder whose rear end engages with the flying object when the flying object is housed, and the inner firing cylinder is an inner firing cylinder. An external launch cylinder to be inserted, adjusting means for adjusting the frictional force between the front internal launch cylinder section and the rear internal launch cylinder section of the external launch cylinder and the internal launch cylinder, and an internal launch cylinder and a flying object in the external launch cylinder. It is provided with a front lid and a rear lid mounted on the front and rear surfaces of the outer launch cylinder in the housed state.

(Operation) In the flying object launching device having the above configuration, when a launch command is given to the flying object and its rocket motor is ignited, the rear lid is blown off by the blast emitted from the rocket motor, and at the same time, the rear inner launch cylinder The part moves rearward by the blast force, and the flying object moves forward by the blast force. At this time, the front inner surface launch cylinder portion engaged with the flying object is pushed forward, crushing the front lid, and when the flying object comes out of the outer surface launch tube, it receives wind pressure in the circumferential direction of the flying object and is divided. And fly away from the flying object.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows the configuration of this flying object launching apparatus. In this flying object launching apparatus, the launching cylinder has a double structure, and the inner surface launching cylinder 21 is composed of a front inner surface launching cylinder portion 211 and a rear inner surface launching cylinder portion 212. . Each of the inner firing cylinder portions 211 and 212 can adjust the frictional force by a front adjusting screw 23 and a rear adjusting screw 24 that penetrate from the side surface of the outer firing cylinder 22, respectively. The front inner surface launch cylinder 211 is composed of a plurality of block pieces,
The other end is engaged with the flying object 25. 26 is the front lid, 27
Is the back lid.

The operation of the above configuration will be described below with reference to FIG.

FIG. 2 shows a situation immediately after the launch vehicle is launched. First, a launch command is given to the launch vehicle 25, and when the rocket motor is ignited, the rear lid 27 is blown off by the blast released from the rocket motor. At the same time, the rear inner firing cylinder 212 moves rearward due to the blast force. Flying object 2
When 5 moves forward due to the blasting force, the front inner surface launch cylinder 211 is pushed forward because it is engaged with the flying object 25, and crushes the front lid 26. When the flying object 25 escapes from the outer firing cylinder 22, the front inner firing cylinder part 211 receives wind pressure in the circumferential direction of the flying object 25, and is divided into two pieces.
Becomes scattered away from.

The change in the reaction force given to the shooter by the above action is the third
Shown in the figure. In the figure, + indicates a forward direction, and-indicates a backward direction.

First, (a) from the time t1 at which the rocket motor starts blast discharge to the time t2 at which the front lid 26 is crushed by the front inner surface launching cylinder portion 211 in which the flying object 25 moves forward and is engaged.
A reaction force in the positive direction as shown in FIG. At the same time, from the time of blast discharge start t1 to the time t2 at which the rear lid 27 is crushed, a negative reaction force is generated as shown in FIG.

Next, from the time t1 at which the flying object 25 starts to move forward to the time t3 at which the detachment of the front inner surface firing tube portion 211 from the outer surface firing tube 22 is completed, the reaction of the friction force F1 in the positive direction as shown in FIG. Force is generated. On the other hand, from the time t1 when the forward movement of the flying object 25 starts, to the time t4 when the rear inner firing cylinder portion 212 moves rearward by the ballast force and separates from the outer firing cylinder 22, the negative frictional force F2 as shown in FIG. A directional reaction occurs.

Further, from the time point t3 at which the detachment of the front inner surface launch tube portion 211 is completed to the time point t5 at which the detachment of the flying object 25 from the outer surface launch tube 22 is completed, the frictional force of the flying object 25 to the outer surface launch tube 22 is shown in FIG. Negative + direction reaction force is generated. Further, from the time point t4 when the detachment of the rear internal firing cylinder 212 is completed, the ballast protruding from the rear internal firing cylinder 212 until the flying object 25 completely disengages from the external firing cylinder 22 in one direction as shown in FIG. A reaction force occurs. When the respective reaction forces from FIG. (A) to FIG. (F) are combined, almost all of the total reaction force is canceled as shown in FIG.

Therefore, the projectile launching device having the above configuration can suppress the reaction force at the time of projectile launching to a very small amount, thereby reducing the burden on the shooter and maintaining the projectile launching direction safely and reliably. become.
