Description

Pressurization launching device for airborne buried weapon

Technical Field

The invention belongs to the field of airborne weapon launching, and particularly relates to a pressurized launching device for an airborne buried weapon.

Background

The launching of airborne buried weapons currently mainly relies on the ejection of the stores pylon or the launching of the weapons along the rack slide rail after the stores pylon extends out of the weapons bay. In general, the buried weapon bay needs to have enough space to accommodate the motion envelope of the buried weapon being ejected from the bay, or the motion envelope of the rack extending out of the bay with the weapon, which puts high demands on the design of the weapon bay structure, bay doors and drive mechanisms, further squeezing the otherwise very limited internal space of the body. In addition, the mode of using the hanging frame to launch the embedded weapon leads the embedded weapon not to be stacked in the aircraft and can not meet the requirement of high-density mounting of the future fighter.

Therefore, a new type of embedded weapon launching method is needed to solve the problems that the traditional rack launching mode occupies a large space, is complex in mechanism and cannot meet the requirement of high-density mounting of embedded weapons. The pressurized launching method of the airborne buried weapon can solve the problems.

Detailed Description

Referring to fig. 1 to 3, fig. 1 to 3 show a pressurized launching device of an airborne buried weapon, which mainly comprises an airborne machine 1, a weapon cabin 2, a pressurized launching device 3, a pressurized launching tube 31, a gas generator 32, a front baffle 33, a front bracket 34, a middle bracket 35, a rear bracket 36 and a buried weapon 4.

The front baffle 33 is connected to the pressurized launch canister 31 for mounting and securing the gasifier 32. The space between the forward baffle 33 and the forward carrier 34 serves as a plenum for pressurizing the gasifier 32. The front bracket 34 covers the head of the buried weapon and acts as a piston that moves backward along the pressurized launch barrel 31 after being struck by the high pressure gas generated by the operation of the gas generator 32, thereby pushing the buried weapon 4 backward along the axis of the launch barrel. The intermediate and

rear brackets

35, 36 are fixed axially relative to the buried weapon 4, and act as a bearing for the buried weapon 4, moving with it and finally leaving the pressurized launch canister 31 one after the other. After the front bracket 34 pushes the buried weapon 4 completely out of the pressurized launch barrel 31, the buried weapon 4 is fired; the specific launching process, as shown in fig. 4, is a schematic view of the pressurized launching process of the buried weapon shown in fig. 4 as 1, 2, 3, 4.

The front bracket 34, the middle bracket 35 and the rear bracket 36 can be designed into split combination type, are combined together in the pressurizing launching tube 31, completely cover the embedded weapon 4 in the circumferential direction, and are separated from the petals by means of internal elastic elements after being pushed away from the pressurizing launching tube 31, and are dispersed under the impact of air flow and are far away from the embedded weapon 4.

As a preferred embodiment of this embodiment, the plurality of segments of the weapon carrier hold the buried weapon 4. Elastic pieces are clamped between the split structures of the weapon bracket; after the weapon carrier is disengaged from the pressurized launch barrel 31, the split structure of the weapon carrier separates under the action of the elastic force and disengages from the buried weapon 4.

As another preferred embodiment of this embodiment, an actuator is disposed between the split structures of the weapon carrier; after the weapon carrier is disengaged from the pressurized launch barrel 31, the split structure of the weapon carrier is separated under the thrust of the actuator and disengaged from the buried weapon 4.

As a preferred embodiment of this embodiment, the pressurized launching device 3 is further provided with an interface unit for connecting the onboard control system and the control unit of the buried weapon 4. Specifically, the interface unit may be mounted on the pressurized launch canister 31 or the front baffle 33.

Further, as shown in FIG. 2, the pressurized launch device 3 may include a plurality of pressurized launch barrels 31, each of the pressurized launch barrels 31 having a gas generator 32 and a weapon carrier disposed therein. The gas generator 32 is fixedly installed at the front end of the pressurizing launch barrel 31; a weapon carrier is slidably disposed within the pressurized launch barrel 31, the weapon carrier being adapted to support an embedded weapon 4.

The pressurizing launching device designed by the invention adopts a piston-like motion mode, the motion direction of the embedded weapon 4 is the axis direction, so that each launching load can be completely packaged in a closed pressurizing launching device 3, the appearance of the pressurizing launching device 3 can be designed according to the internal space of the weapon cabin 2 and compactly arranged, and thus, the intensive mounting of the embedded weapon 4 in the weapon cabin 2 is realized, and compared with the traditional weapon mounting mode, the utilization rate of the space of the weapon cabin 2 is higher.

The pressurizing pressure and the projectile support shape of the pressurizing launching device 3 designed by the invention can be adjusted according to the quality and the launching speed requirements of the buried weapon 4, can adapt to different launching requirements of different weapons, and has higher universality.

The pressurizing launching device 3 designed by the invention can be integrally conveyed into the weapon cabin 2 to be fixed after ground assembly is finished, is simpler and more convenient compared with the traditional weapon mounting mode, and saves the preparation time of the airplane on the ground.
