Abstract

The invention discloses an underwater balanced launching device and a launching method thereof. The underwater balanced launching device comprises a launching cylinder, a bottom support and a balance cavity, wherein the launching cylinder comprises a launching section and a power section, a launcher is arranged in the launching section, a power source is arranged in the power section, the launching section and the power section are separated through the bottom support, and the bottom support can slide along the launching section under the action of external force, and prevents the power source from leaking out of the launching cylinder and prevents external water flow from flowing into the launching cylinder; and a liquid pushing component is arranged in the balance cavity, the balance cavity is filled with liquid, one end of the balance cavity communicates with the power section, the other end of the balance cavity communicates with the outside, and the liquid pushing component can move along the balance cavity under the action of external thrust. The underwater launching recoil force can be reduced, and meanwhile the problems of high-pressure gas overflow, water hammer impact and the like are solved.

Description

technical field

[0001] The invention relates to the technical field of underwater launching, in particular to an underwater balanced launching device and a launching method. Background technique

[0002] Compared with ground launch, underwater launch has many difficulties. Including underwater sealing, high-pressure gas impact, cross-flow load, etc., all make the existing launching methods have more restrictions in use. One of the difficulties in underwater launching is that when launching on a small platform, the recoil force during the launching process will cause a large attitude change of the platform, which will affect the normal operation of the platform and the exit attitude of the missile. Therefore, by balancing the recoil force, it is possible to launch a larger projectile on a smaller platform.

[0003] Such as figure 1 As shown, the existing underwater launching device includes a launch tube and a gas generator. When the aircraft in the launching tube needs t...
