Multi-type compatible high-precision ground static testing stand for rocket engine

Abstract

The invention relates to a multi-type compatible high-precision ground static testing stand for a rocket engine. The testing stand is composed of a stand system and an in-situ calibration system thereon; the stand system is provided with a movable rack, a counterweight clasp, a counterweight module and a plate spring, and the counterweight clasp and counterweight module are combined, match a solid rocket engine sample and them mounted on the movable rack; and the in-situ calibration system comprise an oil hydraulic press, a standard thrust sensor, a work thrust sensor, a standard calibration value table and an accurate number table. The counterweight clasps and modules of different specifications can match solid rocket engine samples of different types. The counterweight clasps and modules of different specifications are used to match the solid rocket engine samples of different types, the standard testing stand is used to test the engines of different types, so that the testing stand can be used flexibility for multiple types, the standard testing stand is compatible with and adapted to small solid rocket engine, and the testing stand has the advantages of reasonable structure, convenient adjustment, safe operation and reliable data.

Description

technical field [0001] The invention relates to a performance testing device for a solid rocket motor, in particular to a multi-type compatible high-precision ground stationary test bench for rocket motors. Background technique [0002] The solid rocket motor high-precision ground stationary test bench is a relatively expensive solid rocket motor performance testing equipment with strict maintenance conditions. Conventional high-precision test benches generally can only meet the detection needs of a certain type of solid rocket motor, and can neither be used for testing smaller types of solid rocket motors, nor can they be used for testing larger types of solid rocket motors. If the high-precision test bench and the solid rocket motor are paired according to the type commonly used in the industry, the disadvantages are: waste of testing costs and low testing efficiency. If the method of "big horse and small cart" or "big cart with small horse" is used to adapt a test bench ...

AI Technical Summary

Problems solved by technology

Conventional high-precision test benches can only meet the detection needs of a certain type of solid rocket motor, and cannot be used to detect smaller types of solid rocket motors, let alone larger types of solid rocket motors

If the high-precision test bench and the solid rocket motor are paired according to the type commonly used in the industry, the disadvantages are: waste of testing costs and low testing efficiency

If the method of "big horse and small cart" or "big cart with small horse" is used to adapt a test bench to various types of solid rocket motors, the result will be: increase the test risk and reduce the detection accuracy
