Abstract

The invention discloses a processing method of a thin-walled vase-shaped cooling room. The method comprises the steps of firstly, manufacturing a workblank of the thin-walled vase-shaped cooling room; filling an inner cavity of the cooling room with gypsum; and finally, carrying out rough processing and finish processing to obtain the thin-walled vase-shaped cooling room. According to the processing method provided by the invention, the procedures are reasonably arranged, the working efficiency is high, the manufacturing cost is low, the problem that parts deform during processing is effectively solved, the utilization rate of raw materials is greatly increased, and the processing accuracy and surface quality of parts are improved.

Description

technical field [0001] The invention relates to parts of a thrust chamber of a liquid rocket ramjet, in particular to a processing method for a thin-walled vase-shaped cooling chamber of the thrust chamber of a liquid rocket ramjet. Background technique [0002] In the field of liquid rocket engines, thrust is the source of power for missile flight, and liquid fuel combustion produces jet flow through the thrust chamber to generate thrust to boost missile flight. The thrust chamber is composed of booster chamber, cooling chamber and injector, such as figure 1 Shown is the thrust chamber where the component cooling chamber. The surface of the cooling chamber is composed of dozens of radioactive grooves. Many grooves can play a good cooling role to reduce the temperature of the combustion chamber and enhance the high temperature resistance of the missile material, so that the missile can hit the target smoothly. Therefore, Thin-walled vase-like radioactive groove cooling cha...
