Abstract

The invention relates to a 4-25N attitude control engine vacuum thermal environment steady-state thrust measurement device. The device comprises a pedestal adapter frame, damping blocks, a fixed frame, a balance adapter plate, a single component force balance measurement device, a propellant pipeline and propellant pipeline fixing devices. Multiple damping blocks are evenly installed between the pedestal adapter frame and the fixed frame. The single component force balance measurement device is installed on the fixed frame through the balance adapter plate. Multiple propellant pipeline fixing devices are fixedly installed at the periphery of the fixed frame. The propellant pipeline is installed through the propellant pipeline fixing devices. One end of the propellant pipeline is communicated with an external propellant supply system, and the other end is communicated with the propellant inlet of an attitude control engine to be measured. The requirement for small thrust measurement of the 4-25N attitude control engine can be met so that the problems of the pipeline constraint and the uncertainty of vibration introduction can be solved.

Description

technical field [0001] The invention relates to aerospace liquid engine test, in particular to a vacuum thermal environment steady-state thrust measuring device for a 4-25N attitude control engine. Background technique [0002] As one of the most mature propulsion systems at present, the liquid rocket engine has many unique advantages. It is still the main propulsion system that various countries strive to develop, and has achieved many achievements in both high thrust and small thrust. At present, the United States is still in most propulsion systems. Russia is leading the world in terms of systems, while Russia continues to maintain its leading position in liquid propulsion, especially high-thrust liquid rockets. The European Union and Japan are catching up with the technological level of the United States. Compete. [0003] A rocket engine is part of a rocket's propulsion system. The propulsion system is composed of engine (solid, hydraulic, stamping, attitude control),...
