Problems solved by technology

The reference point selected by the usual method is determined by experience, and the accuracy is not high. When the thrust control requirements are strict or when the system pressure and the flow resistance of the pipeline system fluctuate greatly, the thrust unilaterally exceeds the tolerance (too large or small) greater risk

Abstract

The present application provides a pressure matching method and a storage medium for an attitude-orbit control liquid rocket engine. The pressure matching method includes: selecting the position of the engine to be adjusted, obtaining calculation constraints; establishing the deviation and the theoretical maximum thrust corresponding to the position. The corresponding pressure drop value of the throttling part, the deviation corresponding to the theoretical minimum thrust of the machine position and the equation group corresponding to the pressure drop value of the throttle part; solve the established equations to obtain the theoretical maximum thrust of the machine position The corresponding deviation and the deviation corresponding to the theoretical minimum thrust of the machine position; calculate the pressure drop of the throttling component according to the pressure drop values ​​of the two throttle components obtained from the solution; set the actual pressure drop according to the calculated pressure drop of the throttle component The pressure drop of the throttling part is used to complete the pressure matching of the liquid rocket engine for attitude and orbit control. This application can reduce the risk of thrust unilateral out-of-tolerance due to inappropriate selection of pressure matching reference points, and has the characteristics of high accuracy.

Description

technical field [0001] The application belongs to the technical field of attitude and orbit control of missile-type aircraft, and in particular relates to a pressure matching method and a storage medium of an attitude and orbit control rocket engine. Background technique [0002] Attitude and orbit control rocket engines are usually equipped with multiple thrusters to achieve attitude control of aircraft roll, pitch, yaw, and speed correction. It has the characteristics of a wide thrust range. Throttle components with different throttle pressure drops are usually installed on each thrust branch of the engine to eliminate the influence of differences in flow resistance of piping systems at different installation locations, processing deviations of the thruster itself, and differences in inlet pressure of different types of thrusters, thereby achieving system pressure. trim. [0003] In the actual working process, the system pressure and pipeline system flow resistance fluctu...
