Problems solved by technology

[0005] The simple installation platform needs to design tooling according to different sizes of test pieces and different installation angles, which has poor versatility, and because the test pieces need to be adjusted at multiple angles on the rotating arm, too many screw holes will affect the strength of the rotating arm, and at the same time Unable to measure the axial thrust of the specimen after ignition

Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing:

[0037] Such as figure 1 As shown, it is a solid rocket motor centrifugal overload test system in the present invention, and the system includes a motor 20, a coupling 30 and a rotating arm 1 from bottom to top, and the motor 20 drives the rotating arm 1 to rotate through the coupling 30, and the rotating arm The end of 1 is provided with an installation platform 10, through the rotation of the rotating arm 1, the test piece 5 in the installation platform 10 is provided with operating conditions such as acceleration, fast acceleration and lateral overload, and by controlling the ignition time of the test piece 5, the rocket engine can be reproduced. In the high overload environment under different attitudes during operation, real-time test data can be obtained by monitoring and controlling the test state, which provides a basis for the study of the flow field and thermal str...

Abstract

The invention discloses an installation device for a centrifugal overload test of a solid rocket engine. The installation device comprises a rotating arm, an installation platform and steel wire tensioning mechanisms, wherein the installation platform is rotatably connected with the outer end of the rotating arm through a rotating shaft system; the rotating arm is internally provided with a plurality of lifting bolts; a cavity is formed between each lifting bolt and the installation platform; the steel wire tensioning mechanisms are arranged in the cavities; the first end of each steel wire tensioning mechanism is fixedly connected with the corresponding lifting bolt, and the second end of each steel wire tensioning mechanism is fixedly connected with the installation platform; a test piece is arranged in the installation platform. According to the installation device disclosed by the invention, the rotating shaft system has a locking function, bears the mass of a rotating cabin and installation parts in the rotating cabin and a transferred force and is conductive to installing the test-piece and adjusting the angle of the test-piece; in the meantime, the steel wire tensioning mechanisms are simple in structure, convenient to operate, not only are capable of overcoming the torque generated by centroid change in a test-piece ignition process, but also are applicable to length and angle change generated when the rotating cabin is installed in different angles.

Description

technical field [0001] The invention relates to a centrifugal overload test device, in particular to an installation device for a solid rocket motor centrifugal overload test. 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 repeatedly on the groun...
