Abstract

The invention discloses a prestressed actively-coolable artillery pipe made from a composite material. The prestressed actively-coolable artillery pipe comprises an artillery pipe body and an artillery tail, wherein the artillery pipe body is externally provided with a carbon fiber composite material reinforcement layer and comprises a steel lining pipe, the steel lining pipe is externally provided with steel interlayer pressure-bearing spacer bars, the gap between the lining pipe and the carbon fiber composite material reinforcement layer is a cooling channel, the cooling channel is providedwith a cooling liquid inlet and a cooling liquid outlet, the inlet is connected with a cooling liquid storage tank through a pipeline provided with a pump, and the outlet is connected with the coolingliquid storage tank through a pipeline provided with a radiator. The carbon fiber composite material reinforcement layer is wound around the outside of the steel interlayer pressure-bearing spacer bars. The weight of the artillery pipe can be effectively decreased, and the high temperature produced by the artillery pipe due to shooting can be also effectively reduced.

Description

technical field [0001] The invention relates to a cannon barrel. Background technique [0002] Napoleon had a famous saying "artillery is the god of war", which fully explained the important position of artillery in war. Artillery still plays an irreplaceable and important role in modern warfare. In order to ensure the continuity of firepower and shooting power of the artillery, it must have a high rate of fire. During the shooting process, the high-temperature and high-pressure gunpowder gas generated will form a pulsed high-temperature flow in the gun barrel, and the friction between the projectile body, the belt and the barrel will cause the barrel to heat up sharply, which will cause adverse thermal effects on the gun. Such as inner bore ablation wear, barrel thermal stress, thermal bending, decreased shooting accuracy, etc. After continuous shooting, these unfavorable thermal effects will be significantly strengthened, which will significantly shorten the service lif...
