Rocket engine main thrust vacuum field calibration system

Abstract

The invention discloses a rocket engine main thrust vacuum field calibration system which includes a pressurized pipe, a hydraulic cylinder, a loading rod A, a standard force sensor, a loading rod B,a rocket engine, a loading flange, a main thrust sensor, a transfer frame, a vacuum cabin, a servo motor, a control cable and a controller. The pressurized pipe is connected with the hydraulic cylinder. The hydraulic cylinder is connected with the loading rod A, the standard force sensor and the loading rod B, and the hydraulic cylinder and the rocket engine are installed in a series connection manner. The hydraulic cylinder is also installed together with the loading flange, the main thrust sensor, the transfer frame and the rocket engine in a series connection manner. The loading rod A, thestandard force sensor and the loading rod B are arranged in the center holes of the loading flange, the main thrust sensor and the transfer frame. The pressurized pipe passes through the vacuum cabinto be connected with the servo motor. The servo motor is connected with the control cable. The control cable is connected with the controller. The controller controls the action of the servo motor through the control cable to result in the change of the loading force of the hydraulic cylinder, thus realizing automatic loading.

Description

technical field [0001] The invention relates to a rocket engine main thrust vacuum on-site calibration system, in particular to a rocket engine main thrust vacuum automatic calibration system, which is suitable for in-situ main thrust automatic calibration of a rocket engine in a vacuum environment in a vacuum chamber. Background technique [0002] Pre-research, design, production, and test are the four basic links in the development of any new type of rocket engine. Among them, the test work is extremely important, and some engine experts even think that the rocket engine is not the result of research, but the crystallization of experiments. This is mainly because almost all the problems encountered in the process of developing the engine were solved by experiments. [0003] The working process of the rocket engine is relatively complicated. In theoretical research, it is impossible to describe this process clearly by analysis and calculation alone, and it is also impossib...

Problems solved by technology

[0003] The working process of the rocket engine is relatively complicated. In theoretical research, it is impossible to describe this process clearly by analyzing and calculating alone, and it is also impossible to strictly determine the quantitative relationship between the various performance parameters of the engine.
