Centering device and method for cleaning solid rocket motor with high-pressure water jet cleaning gun

Abstract

The invention discloses an aligning device and method for cleaning of a solid rocket engine through a high-pressure water jetting cleaning gun, belongs to the technical field of engine charge, and particularly relates to the device and method capable of enabling the central line of a high-pressure water jetting gun barrel to coincide with the central line of the engine. The aligning device for cleaning of the solid rocket engine through the high-pressure water jetting cleaning gun comprises the high-pressure water jetting cleaning gun, an infrared positioning lamp, a front blocking cover, a rear blocking cover, a position regulating device and a target plate. An engine case is placed on the position regulating device, the infrared positioning lamp is mounted at the center position of the head of the high-pressure water jetting cleaning gun, and the engine case is located between the high-pressure water jetting cleaning gun and the target plate. By adjusting the position regulating device, infrared rays emitted by an infrared emitting device sequentially penetrate through the front blocking cover and the rear blocking cover and are irradiated to the marked position of the target plate, so that aligning is completed. By means of the aligning device and method, the problems that the central line of the gun barrel deviates from the central line of the engine, and consequently safety or quality is affected by friction between the gun head and an explosive column in the engine and the inner wall of the engine are solved.

Description

Technical field [0001] The invention belongs to the technical field of engine charge, and particularly relates to a device and method capable of making the center line of a high-pressure water jet gun barrel coincide with the center line of the engine and avoiding friction between the gun head and the grain or shell in the engine. Background technique [0002] The high-pressure water jet cleaning solid rocket motor charge is achieved by injecting a high-pressure water jet on the surface of the solid propellant, coating layer, and thermal insulation layer to realize the cutting and cleaning of the solid propellant, coating layer and thermal insulation layer. The traditional manual cleaning is safe and reliable, greatly reducing the risk, and this high-pressure water jet cleaning method is more efficient than the traditional manual cleaning method. The inner wall of the engine after the water jet cleaning is as smooth as ever and without damage, ensuring the expensive Because of th...
