Abstract

PURPOSE:To permit the obtaining of a large firing elevation upon launching a missile by a method wherein an air bag, propelling the missile, is attached to the inside of a launching tube for launching the missile while a gas generator, exploded by ignition and elongate the air bag, is provided in the air bag. CONSTITUTION:The launching device, arranged on a self-propelling vehicle and the like, is provided with an air bag 1, elongated into the launching direction of a missile 5 and propelling the missile 5 through a pressure receiving plate 3, in a launching tube 6 while a gas generator 2, exploded when ignited through an ignition controller 4 and inflating suddenly the gas in the air bag 1 to elongate the air bag 1, is provided in the air bag 1. The air bag 1 is formed of 'Kevlar(R)' woven cloth or the like coated with chloroprene rubber and is stored in the bottom part of the launching tube 6 under a condition that it is folded before launching. The missile 5 is launched by the air bag 1 inflated suddenly and after the missile is released from the launching tube 6, a booster is ignited and propulsion is continued by the booster.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a projectile of a flying vehicle, which is applied to launch a flying vehicle.

[0002]

2. Description of the Related Art FIG. 3 is an explanatory view of a conventional flying body injection apparatus used for launching a flying body. In the figure, the conventional projectile ejecting device has a relatively small angle of flight when the projectile 05 is launched from the launch tube 06.
The vehicle 05 is equipped with a rocket motor 01 as a booster for propelling the vehicle 05.

[0003]

As described above, in the conventional projectile ejecting device for the flying body, since the projecting angle of the flying body 05 is relatively small, the topography to be used is restricted. For example, it cannot be used in the mountains and the confidentiality of the launching point is not sufficient. Therefore, it suffices to increase this angle of incidence, but the conventional rocket motor 0 is used as a booster for propelling the projectile 05 to the projectile 05.
1 is equipped, and the booster's propulsive force is insufficient, and it is not possible to make a large elevation angle close to vertical. Further, the launch cylinder 06 is damaged by the blast injected from the rocket motor 01, and the number of reuses of the launch cylinder 06 is limited to about 3 times.

[0004]

[Means for Solving the Problems] A projectile ejecting device according to the present invention is intended to solve the above-mentioned problems, and is installed in a launching tube for launching a projectile in the launching direction of the projectile. An airbag that extends to propel the flying body, and a gas generator that is mounted in the airbag and explodes when ignited to explode the gas in the airbag to extend the airbag It is characterized by the configuration.

[0005]

In other words, in the projectile ejecting device according to the present invention, the device is mounted in the launch tube for launching the projectile, and extends in the projecting direction of the projectile in the airbag for propelling the projectile. When a gas generator is installed and ignited, it explodes and explodes the gas in the airbag to expand the airbag.When launching a projectile, the airbag expands to propel the projectile. Then, after the projectile is completely separated from the launch tube, the booster of the projectile is ignited to continue the propulsion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view of a jetting device for a flying object according to an embodiment of the present invention, and FIG. 2 is an explanatory diagram of a jetting device for a flying object according to another embodiment of the present invention. In FIG. 1, the projectile ejecting device according to the present embodiment is used for launching a projectile, and when the projecting angle of the projectile is small, the terrain to be used is restricted. Since it cannot be used in the mountains, the projectile of this projectile is designed so that the projectile 5 can be launched from the launch tube 6 up to an angle of 90 deg.
The projectile 5 is propelled by utilizing the inflation pressure of the airbag 1 when the air bag 1 is launched. When the gas generator 2 mounted in the airbag 1 is ignited, Then, the pressure receiving plate 3 receives the pressure and propels the flying body 5. Airbag 1
Is made of Kevlar woven cloth coated with chloroprene rubber. The gas generator 2 is composed of gunpowder and a gas generating agent such as sodium azide pellets. Pressure plate 3
Is made of polyurethane or the like. The ignition controller 4 supplies squib power to the gas generator 2. The airbag 1 is housed in the launch tube 6 and fires the flying body 5.

When the ignition controller 4 receives the launch signal of the flying object 5, the squib power source is supplied to the gas generator 2. When the gunpowder of the gas generator 2 is ignited, the gas generating agent in the airbag 1 rapidly generates gas, and the airbag 1 inflates rapidly. This pressure is transmitted as a propulsive force to the flying vehicle 5 via the pressure receiving plate 3. As a result, the flying vehicle 5 can be removed from the launch tube 6 without using the rocket motor of the booster. For example, 90 °
Assuming that the internal pressure of the airbag 1 is 3 kg / cm ² and the weight of the flying vehicle 5 is 600 kg, the launch tube 6
The speed when leaving the car is about 20 m / s. In addition,
As shown in FIG. 2, by mounting a plurality of airbags 1 and gas generators 2 in the firing barrel 6, the propulsive force of the airbags 1 can be further enhanced.
Then, after the projectile 5 is completely separated from the launch tube 6, the booster of the projectile 5 is ignited and the propulsion of the projectile 5 is continued.

[0008] As described above, since these projectiles for ejecting a flying body are provided to the flying body 5 in the past, since the propelling force is applied to the flying body 5 by the airbag 1 when the flying body 5 is launched. A rocket motor booster enables a sufficiently high-angle or vertical launch. Therefore,
The restrictions on the terrain used are reduced, and it can be placed in the depths of mountains such as in forests and valleys, increasing the concealment of the launch point. Further, when the projectile 5 is launched from the launch tube 6, the influence of the blast injected from the rocket motor is almost eliminated, and the number of times the launch tube 6 is reused is increased.

[0009]

The projectile ejecting device according to the present invention is configured as described above, and when the projectile is launched, the projectile is propelled by the expansion of the airbag, so the projectile is launched. There is no restriction on the terrain that can be used because of the large shooting angle. And since the projectile is completely separated from the launch tube, the booster of the projectile is ignited, so that the launch tube is not affected by the blast injected from the booster of the projectile and the number of reuses of the launch tube is reduced. To increase.
