SUMMARY OF THE INVENTION In the above-described conventional launcher for a flying vehicle, the rocket motor igniter loses the ignition charge after its function is completed, but the other parts are unnecessary. It remains in the flying body, and the mass of the flying body becomes large, which deteriorates the flying performance of the flying body.

The rocket motor igniter is incorporated in the rocket motor at the time of manufacture, and is transported and stored in a state of being assembled into a flying body and a launch barrel. Therefore, if the rocket motor igniter accidentally ignites, the rocket motor igniter is rocket motor. Has a risk of being activated.

The present invention is intended to provide a projectile launching device for a flying body which can solve the above problems.

DISCLOSURE OF THE INVENTION The present invention relates to a launching device for a flying vehicle, which comprises a launching barrel for housing a flying vehicle having a rocket motor as a propellant and a rocket motor igniting device. It is characterized by being inserted into the rocket motor from the rear of the rocket motor and fixed to the launch tube.

[0010]

The rocket motor ignition device is inserted into the rocket motor from the rear end of the rocket motor and fixed to the launch cylinder before the launch. As a result, when the rocket motor igniter is activated and the rocket motor is ignited to launch the projectile, the rocket motor igniter is separated from the projectile to be launched and does not fly with the projectile. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1 showing the whole of the present embodiment,
The launch tube 3 has its rear end pivotally attached to the base 20 at a point indicated by reference numeral 22, and can be rotated around a point 22 by a cylinder 21 to change its posture.
The projectile 2 is stored in the launch tube 3. The flying vehicle 2 has a built-in rocket motor 4 as a propulsion device. The rocket motor 4 is filled with rocket motor propellant 14 having an axial hole in the center thereof,
A nozzle 8 for ejecting the combustion gas of the rocket motor propellant 14 backward is provided at the rear end. The rocket motor igniter 1 is inserted into the central axial hole of the rocket motor propellant 4 of the rocket motor 4 from the rear of the rocket motor 4 and is bolted to the rear lid 5 of the launch tube 3.

The launch tube 3 has an opening 5'at the center thereof.
And a front lid 5 which is detachably attached to the rear end of the firing barrel 3 and a front lid 5a whose one end is pivotally attached to the front end of the firing barrel 3 at a point 5b. When the launch tube 3 is transported or stored, as shown in FIG. 4A, the projectile 2 is housed in the launch tube 3, and the rocket motor ignition device 1 is attached to the projectile 2. And the lid 12 is attached to the rear lid 5 so as to cover the opening 5 ′ of the rear lid 5.

FIG. 2 shows the details of the periphery of the rocket motor ignition device 1, and FIG. 3 shows a sectional view of the rocket motor ignition device 1. The rocket motor ignition device 1 is provided with an ignition charge 9 in a case 10 having a plurality of through holes 10a at a front end thereof, and has an initiator 11 at a rear end thereof for transmitting an electric signal via an ignition cable 16. Further, a holding portion 6 is provided in a portion between the ignition charge 9 and the initiator 11.
Is provided, an annular rubber seal 7 is provided so as to surround the front end portion of the holding portion 6, and the auxiliary ignition charge 13 is filled between the ignition charge 9 and the initiator 11 of the holding portion 6. Has been done. In addition, a flange 6a is provided so as to project from a portion of the holding portion 6 immediately before the initiator 11.

In this embodiment, before the projectile 2 is launched, the lid 12 is removed from the launch tube 3, and the rocket motor ignition device 1 is opened in the rear lid 5 of the launch tube 3 and the nozzle 8 is formed. After that, the rocket motor 4 is inserted into the rocket motor 4 from behind, and the flange 6a of the holding portion 6 is fixed to the rear lid 5 with the bolt 17. At this time, the seal 7 of the holder contacts the inner surface of the nozzle 8 to keep the rocket motor 4 airtight and facilitate ignition.

In this state, when the initiator 11 is ignited by an electric signal from the outside, the auxiliary ignition charge 13 and the ignition charge 9 are ignited in the same manner as in a general rocket motor ignition device, and the ignition charge shown in FIG.
As shown in (b), the ignition combustion gas 15 is blown from the case 10 to ignite the rocket motor 4 and the combustion of the rocket motor propellant 14 is started. The projectile 2 is launched from the launch tube 3 by the thrust obtained by ejecting the combustion gas of the rocket motor propellant 14 backward from the nozzle 8.

In this case, the rocket motor ignition device 1 is
Since it is inserted from the rear of the rocket motor 4,
As shown in FIG. 4C, the rocket motor propellant 1
The rocket motor 4 is separated from the rocket motor 4 by the combustion gas 4 and is blown off to the rear of the launch tube 3 together with the rear lid 5.

As described above, in this embodiment, the launched flying body 3 separates the rocket motor igniter 1 to fly. Therefore, it is possible to reduce the mass of the flying object 3 and improve its flying performance.

Further, since the rocket motor igniter 1 is not mounted on the flying body 3 during transportation / storage and is mounted immediately before launch, the rocket motor igniter 1 is mistaken during transportation / storage of the flying body. It is possible to prevent the rocket motor 4 from malfunctioning due to the ignition.

In the present embodiment, as a safety mechanism of the rocket motor ignition device 1, a conventionally known safe arm switching mechanism may be mounted between the initiator 11 and the ignition charge 9.

[0020]

According to the present invention, since the rocket motor ignition device is inserted into the rocket motor from the rear of the rocket motor and fixed to the launch barrel, the rocket motor ignition device is separated from the flying object after the rocket motor ignition process. , It is possible to reduce the mass of the flying body when it is launched from the launch tube and flies. Also, the rocket motor igniter does not have the mass of the flying body during flight, so
It is possible to make the device simpler than the conventional one without being restricted in terms of shape and mass.

Further, since the rocket motor igniter can be removed to transport and store the flying object, and the rocket motor igniter can be incorporated into the launch cylinder at the time of use,
The safety can be improved.
