Abstract

The invention relates to the field of overload experiment systems, and particularly discloses a solid rocket engine attitude adjusting device applied to a centrifugal overload test. The device comprises an integrated board, and a driving module, a fixing module and a transmission module are arranged on the integrated plate. The transmission module comprises a lead screw, a guide rail and a guide rail sliding block, the guide rail is arranged on the integrated plate, the guide rail sliding block is in sliding connection with the guide rail, a moving seat is arranged on the guide rail sliding block, the lead screw is in threaded transmission connection with the moving seat, and the two ends of the lead screw are rotationally connected with the fixing module. The driving module is fixedly installed on the fixing module, and the output end of the driving module is connected with one end of the lead screw. A connecting part is arranged on the moving seat, a transmission rod is hinged to theconnecting part, and a connecting seat is arranged at one end of the transmission rod. The device has the advantages that the device is driven by the driving module in a super-gravity centrifugal overload environment, and a barrel-shaped fixing tool drives the moving posture of a test body in the barrel-shaped fixing tool to be dynamically adjusted through the transmission module.

Description

technical field [0001] The invention relates to the field of overload experiment systems, in particular to a solid rocket motor attitude adjustment device used in centrifugal overload experiments. Background technique [0002] With the rapid increase of the rocket's flight speed, acceleration and rapid acceleration, as well as the high lateral overload, more complex physical and chemical changes in the combustion and flow field in the engine will occur, seriously affecting the stable operation of the engine in service. It is of great significance to improve the anti-overload ability of the engine to study the change law of the engine flow field under complex working conditions such as high overload and improve the thermal structure of the engine. [0003] For this reason, a solid rocket motor centrifugal overload test system was developed. Through this system, the high overload environment under different attitudes of the rocket engine operation process can be reproduced re...
