Control system of solid-liquid dynamic sounding rocket

Abstract

The invention discloses a control system of a solid-liquid dynamic sounding rocket. The control system is composed of a ground test launching control part and a rocket-borne control part. The control system is mainly used for realizing the following three tasks: converting ground power supply of a rocket-borne device to rocket-borne power supply, completing test preparation before launching the solid-liquid dynamic sounding rocket to realize the functions of launching control, security control, and the like, and carrying out variable thrust control on the solid-liquid dynamic sounding rocket and monitoring, collecting and recording the states. The invention provides a solid-liquid dynamic aircraft control system. By utilizing the solid-liquid dynamic aircraft control system, the functions of monitoring, ignition testing, emergency danger eliminating, and the like to the important rocket-borne device can be realized before the rocket is launched, the rocket-borne control part can realize thrust adjustment control according to control requirements after the rocket is started, and liquid propellant main road and side road channel valves are controlled according to the control requirements to clear residual propellant in a channel after the flight mission is finished. Meanwhile, real-time data acquisition and recording on parameters for reflecting working conditions of a solid-liquid rocket engine are carried out by the rocket-borne control part in the entire flight process.

Description

technical field [0001] The invention belongs to the field of control systems, and in particular relates to a control system of a solid-liquid power 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 and has the characteristics of adjustable thrust and repeatable start. In order to make the solid-liquid rocket engine work in the optimal ratio state, and to monitor, collect and record the state of the rocket-borne device that affects and responds to the flow of liquid propellant, combined with the launch control part of the ground test, realize various state monitoring before launch , Ignition launch, release launch and other tasks. These are important aspects of the development and research of solid-liquid powered sounding rockets. [0003] Existing aircraft or engine testing, launching, and devices are mostly used for aircraft or engines powered by liquid...
