Abstract

The invention provides a launcher barrel cooling water jacket based on turbulent flow blades. The launcher barrel cooling water jacket comprises a water jacket body, a water inlet and a water outlet.The water jacket body is tubular and is fixed to a launcher barrel. The water inlet and the water outlet are located in the upper and lower wall faces of the two ends of the water jacket body correspondingly. A plurality of T-shaped water delivery blades are arranged on the inner wall of the water jacket body in the circumferential direction. Each T-shaped water delivery blade is in a strip shapeand is arranged in the axial direction of the water jacket body. According to the launcher barrel cooling water jacket, the barrel can be cooled efficiently in the continuous shooting process of a launcher.

Description

technical field [0001] The invention relates to a cooling technology for a launching device, in particular to a cooling water jacket for a barrel of a launching device based on spoiler vanes. Background technique [0002] During the continuous shooting of the launching device, the temperature of the barrel continues to rise, which seriously threatens the safety of the propellant and the service life of the barrel. Many launchers use external cooling to reduce barrel temperature. The cooling water flow in the traditional external cooling water jacket has no direction and regularity, and it is easy to form a flow dead zone, which reduces the heat dissipation efficiency; the heat dissipation effect of the flow dead zone is poor, and it is easy to cause uneven cooling of the barrel and cause the barrel to bend. Contents of the invention [0003] The object of the present invention is to provide a cooling water jacket for the barrel of a launcher based on spoiler vanes, which ...
