SOLID-PROPELLANT ROCKET ENGINE Russian patent published in 2001 - IPC

Abstract RU 2173783 C1

FIELD: rocketry. SUBSTANCE: solid-propellant rocket engine has a high aspect ratio body, charge reliably secured on the body and provided with central channel and burning vault equal in length, and nozzle. The body consists of smaller diameter from cylindrical part and larger diameter rear cylindrical part interconnected by conical adapter. Diameter of rear part of body is minimum one-and-half times greater than body front part, and its length is 0.1-0.3 of total length of the body. Nozzle neck is made from ablating material and is provided with step at side of inlet part. EFFECT: prevention of pressure fluctuations in combustion chamber over entire period of engine operation, improved reliability of engine. 2 dwg
