Abstract

The invention discloses an underwater pressure-equalizing exhaust emission experiment device. In the underwater pressure-equalizing exhaust emission experiment device, the situation that the free exhaust motion of a navigation body is difficult to study due to the given motion track of the navigation body is avoided. According to the underwater pressure-equalizing exhaust emission experiment device, the navigation body and a pusher are sequentially arranged in an emission cylinder from top to bottom, the navigation body is pushed by the pusher to make the action of emitting out of the emissioncylinder, the navigation body comprises a head cover and a cylinder body, the head cover is detachably connected to the top of the cylinder body, an exhaust hole is machined in the top of the cylinder body in the circumferential direction of the cylinder body, a first bottom hole is formed in the bottom of the cylinder body, a double-head piston is vertically arranged in the cylinder body, the upper end of the double-head piston is tightly attached to the exhaust hole, the lower end of the double-head piston is arranged at the bottom of the cylinder body, and a sealing ring is arranged outside the exhaust hole of the cylinder body in a sleeving mode. The underwater pressure-equalizing exhaust emission experiment device is used for underwater emission experiments of the navigation body.

Description

technical field

[0001] The invention belongs to the technical field of underwater testing, and in particular relates to an underwater pressure-equalizing exhaust launching experiment device. Background technique

[0002] Submarine-launched weapons occupy a very important position in the marine combat system. Underwater launch technology is the core technology of the submarine-launched weapon system. The launch of submarine-launched missiles includes three important stages: the launch of the vehicle, navigation in the water, and crossing the water surface. There are many factors affecting the whole process, and the force of the vehicle changes drastically. Although it is only a few seconds, it has a decisive influence on the attitude of the vehicle after it emerges from the water, which is related to the success or failure of the underwater launch of the submarine-launched vehicle.

[0003] The underwater movement speed of the vehicle body is relatively high, and the pressure...
