Description

Underwater balance launching device and launching method thereof
Technical Field
The invention relates to the technical field of underwater launching, in particular to an underwater balance launching device and a launching method.
Background
Underwater launch has a great deal of difficulty compared to ground launch. Including underwater seals, high pressure gas impingement, cross flow loading, etc., all make existing launch modes more limited in use. One of the difficulties of underwater launching is that when launching on a small platform, recoil in the launching process can cause the platform to generate great attitude change, which affects the normal work of the platform and also affects the posture of the missile when the missile goes out of the barrel. Thus, by balancing recoil, larger projectiles can be fired on smaller platforms.
As shown in fig. 1, the conventional underwater launching device includes a launch canister and a gas generator. When the aircraft in the launch canister needs underwater launching, after the engine or the fuel gas generator is ignited, a high-pressure area is formed at the tail part of the aircraft, the aircraft is pushed forwards, and the launch canister is pushed backwards. The launching mode enables the launch velocity of the aircraft to have a correlation with the recoil force applied to the platform. For small platforms, the magnitude of recoil severely impacts normal navigation after launch.
The existing underwater launching device has the following defects in the underwater launching process in summary:
1. the recoil of the platform is closely related to the aircraft launch velocity. So that the launch velocity of the aircraft is limited by the recoil that the platform can withstand. Meanwhile, the arrangement position of the launch canister is limited accordingly.
2. A large amount of bubbles are generated in the underwater launching process, and the launching characteristics are obvious. For submarines or other underwater vehicles in underwater battles, the position information of the submarines or other underwater vehicles is hopefully not exposed as much as possible in the launching process. Therefore, it is generally more desirable to have as little as possible amount of gas spilled after launch. And the adoption of high-pressure fuel gas for emission can cause a large amount of gas to leak out, so that the self position is exposed.
3. The water hammer impact characteristics after the shooting are obvious. After underwater launching, seawater outside the launching tube rushes into the launching tube, and under the combined action of inertia force and air mass elasticity, the bottom of the tube bears the shock impact of pressure circulation, and the shock peak value is probably far higher than the local external pressure. Adversely affecting both safety and stealth performance of the aircraft.

As shown in fig. 6, the underwater launching method of the present invention includes the following steps:
step S600: configuring the underwater balance launching device in any one of the above embodiments;
step S610: filling the balancing cavity with liquid; the liquid may be a body of water that fills the balance cavity in an external environment.

step S630: the liquid pushing component is pushed by the power source to move towards one side of the outlet of the liquid storage cavity communicated with the outside, and then recoil is counteracted.
Through the balanced type launching mode, the beneficial effects that can be brought are as follows:
1. reducing recoil during firing. By pushing outside water as a source of reverse impulse, the recoil can be close to zero in an ideal state.
In practical application, the capability of zero recoil launching in the invention can be utilized to launch an aircraft with larger mass on a small-sized and miniature platform, and the speed of the aircraft out of a cylinder is not limited too much. The platform attitude is little interfered by the launching process, and continuous launching can be better realized.
2. Reducing the emission characteristics. Through sealing the gas between the inner and outer barrels, after the launching process is finished, high-pressure gas does not leak, and the self-position exposure of the launching platform caused by the fact that the gas for launching the gas floats to the water surface is avoided.
When the stealthy requirement of transmission platform is higher, the mode of retrieving gas after traditional transmission is difficult to be gaseous recovery completely, and the gas after retrieving can cause the atmospheric pressure in the platform to increase, influences operational environment. This balanced launch structure has avoided retrieving high-pressure gas's problem.
3. The water hammer impact effect of the launch canister is avoided. Because the high-pressure gas is closed after the emission, external water flow can not enter the barrel, and oscillation impact can not be formed in the barrel. The transmission safety and the transmission noise of the platform can be obviously reduced.

3. The underwater balanced launch device of claim 1 wherein one end of the launch canister is open and the other end of the launch canister is closed, the power section being formed between the shoe and the closed end of the launch canister; the underwater balance launching device further comprises an outer barrel and a connecting pipeline, the outer barrel and the launching barrel are arranged side by side, one end of the outer barrel is provided with an end cover, the other end of the outer barrel is communicated with the outside, the balance cavity is formed inside the outer barrel, the liquid pushing component is a piston matched with the inner diameter of the outer barrel, and the balance cavity is communicated with the power section through the connecting pipeline.
4. The underwater balanced launching device of claim 1, wherein the shoe and the liquid pushing component are slidably disposed in the launching tube, the liquid pushing component is a piston matched with the inner diameter of the launching tube, the shoe and the piston are spaced apart from each other and form the power section between the shoe and the piston, the area between the shoe and the port of the launching tube forms the launching section, and the area between the piston and the other port of the launching tube forms the balancing cavity.
5. The underwater balanced launch device of any one of claims 2 to 4 wherein the side of the balance cavity communicating with the outside is provided with a limit structure for resisting the liquid pushing component.
6. The underwater balanced launching device of claim 2 or 3, wherein the end cap is provided at one end of the outer cylinder corresponding to the opening of the launch canister, one end of the connection line is connected to the end cap, and the other end of the connection line is connected to the closed end of the launch canister.
7. The subsea balance launch device of claim 2, wherein said launch canister and said outer canister are concentrically disposed.
8. The underwater balance launching device of claim 1 wherein the launcher is an aircraft and the power source is a high pressure gas.
9. The underwater balanced launching device of claim 1, wherein a limiting structure for resisting against the bottom support is arranged on one side of the launching port of the launching tube.
10. An underwater launching method, comprising:
configuring the subsea launch device of any of claims 1-9;
filling the balancing cavity with liquid;
the bottom support is pushed by the power source to move towards one side of an outlet of the launching tube, so that the launched objects are driven to be launched out of the launching tube;
the liquid pushing component is pushed by the power source to move towards one side of the outlet of the liquid storage cavity communicated with the outside, and then recoil is counteracted.
