A kind of orbital circulation cooling system and cooling method applied to rail gun

Abstract

The invention discloses a circulating cooling system for a railgun rail and a cooling method. Outlets of a first pneumatic powder suction pump and a second pneumatic powder suction pump of the system are connected with a spray nozzle of the railgun rail. The railgun rail is connected with a gas separation device through a pipeline. The gas separation device is connected with a Fe2O3 reproduction device through a pipeline. The Fe2O3 reproduction device is connected with the second pneumatic powder suction pump through a pipeline. The railgun rail is mainly composed of a reaction channel, a trapezoid spray nozzle, a rail inner wall and a rail outer wall. A hollow communicated reaction channel is formed by the rail inner wall and the rail outer wall. The diameter of the reaction channel ranges from 20 mm to 25 mm. The thickness of the rail outer wall ranges from 4.5 mm to 5.5 mm. The side, close to the outer wall, of the inlet end of the reaction channel is provided with the trapezoid spray nozzle. The reaction channel is of a U-shaped structure. According to the circulating cooling system, the spray-out pressure of the spray nozzle is controlled by controlling the flow speed of a reaction medium entering the outer wall channel, continuously circulating cooling can be guaranteed, and the temperature of the railgun rail is lowered quickly.

Description

technical field [0001] The invention relates to a reaction temperature-triggered cooling track, in particular to a track circulation cooling system and cooling method for a rail gun, which keeps the track temperature of an electromagnetic rail gun constant by absorbing heat during the reaction operation. [0002] technical background [0003] In the current research on electromagnetic guns, there is no good solution to the cooling of rail gun rails. The existing cooling measures only use the evaporation and heat absorption of liquid to achieve the cooling effect. Its main disadvantages: (1) During the use of the electromagnetic railgun, the heat generated is very huge, and the evaporation heat absorption cannot completely absorb these heats; (2) the heat absorption cannot be used to keep the temperature of the railgun in a stable state. Contents of the invention [0004] The object of the present invention is to overcome the shortcoming that existing cooling measure exists,...
