Measurement and control system of high-speed spinning test bed of solid rocket engine

Abstract

The invention discloses a measurement and control system of a high-speed spinning test bed of a solid rocket engine, and belongs to the field of rotation test of solid rocket engines. The measurementand control system comprises a control system, a measurement system, a data acquisition and storage system and a security system. When the rotation speed of the high-speed spinning test bed required by a test is less than or equal to 2000rpm, a low-speed signal transmission module uses a sliding ring in the prior art to transmit a control signal and test data to achieve the control on the high-speed spinning test bed; when rotation speed of the high-speed spinning test bed required by the test is 2000-20000rpm, a high-speed control signal and test data are transmitted through a wireless transmission module to achieve the control on the high-speed spinning test bed and transmission of the test data. The measurement and control system of the high-speed spinning test bed of the solid rocket engine has the advantages that the high-speed spinning test bed of the solid rocket engine can be controlled, and the acquisition and storage of the test data can be achieved under the high-speed spinning condition, thereby meeting the requirements of the control of a console on a test device on the high-speed spinning test bed and effective transmission of the test data thereof. The high-speed speed range is 2000-20000rpm.
