Abstract

The invention discloses a rocket-borne monitoring system of a solid-liquid dynamic sounding rocket. The rocket-borne monitoring system is composed of a rocket-borne thrust adjustment controller and a rocket-borne data monitor. The controller and the monitor are both composed of a plurality of monitoring and testing modules. The rocket-borne monitoring system is mainly used for realizing the following four tasks: converting power supply of the rocket-borne monitoring system from ground power supply to rocket-borne power supply, completing control to actions of relative valves according to thrust adjustment control, carrying out monitoring recording on working conditions of a rocket-borne device, and realizing reset control to the rocket-borne device. By utilizing the rocket-borne monitoring system of the solid-liquid dynamic sounding rocket, control to liquid propellant booster valves, main road and side road channel valves is realized in the flight process of the rocket according to control requirements, the function of thrust adjustment is completed, and safety of a conveying system is ensured. The real-time working conditions of a solid-liquid rocket engine can be effectively reflected by data monitoring results.

Description

technical field [0001] The invention belongs to the field of control systems, and in particular relates to an rocket-borne monitoring system of a solid-liquid powered sounding rocket. Background technique [0002] The solid-liquid powered sounding rocket is a new type of aircraft that uses a solid-liquid rocket engine as a power device, has adjustable thrust, and can be started repeatedly. Compared with solid and liquid rocket engines, the entire combustion process of solid-liquid rocket engines is easier to control, but it also has the difficulty of stabilizing the ratio of oxidant and fuel. The ratio has an important influence on the working performance of the solid-liquid rocket engine such as the combustion efficiency and specific impulse of the solid-liquid rocket engine. At present, the research on the adjustment and monitoring of the actual thrust of solid-liquid powered sounding rockets, as well as flow adjustment monitoring and collection records is very scarce.
