Embodiment Construction

[0032] The present invention will be further described below in conjunction with the drawings. Based on the research purpose of the solid-liquid power sounding rocket and the requirements for data collection on board the missile, the present invention designs and implements the projected data device for recording the three axial accelerations of the sounding rocket and part of the working conditions of the rocket engine. It is designed to monitor and control the supply system, pressurization system, and blow-off system of the solid-liquid rocket engine according to the time sequence, so as to play the role of recording the whole process of the function of the rocket engine and the rocket computer, and calculate it based on the stored information The actual thrust of the solid-liquid sounding rocket is compared with the rocket acceleration at that time. The finally completed missile-borne data acquisition device can meet the various performance requirements of solid-liquid power...

Abstract

The invention relates to a device for acquiring rocket-borne data of a solid-liquid power sounding rocket. The device is mainly used for acquiring, processing, monitoring and storing signals output by three uniaxial accelerometers, a pressure transmitter for measuring the pressure of an oxidizing agent storage tank, a pressure transmitter for measuring the pressure of a high-pressure gas cylinder capable of pressurizing the oxidizing agent storage tank, a pressurization working condition conversion electromagnetic valve, an auxiliary circuit blow-off self-locking electromagnetic valve and a main circuit blow-off self-locking electromagnetic valve. According to a rocket-borne data acquisition circuit, core functions of sequential control, data acquisition, signal conditioning, switching value conversion, data caching, data storage, data remote transmission and the like of the data acquisition device can be realized by a control chip; and other functions of voltage stabilization, protection, power supply, electricity conversion control, clock input and the like are required to be realized besides the core functions. By the device, thrust which is actually generated by a solid-liquid rocket engine and accelerations of the rocket in three axial directions can be totally monitored and compared at the working stage of the engine.

Description

Technical field [0001] The invention belongs to the field of rocket-borne data acquisition systems, and particularly relates to a rocket-borne data acquisition device of a solid-liquid powered sounding rocket. Background technique [0002] Solid-liquid sounding rockets are rockets for detection and scientific experiments in near-Earth space. Its main purpose is to conduct space exploration or flight verification tests, and accumulate experience for the development of solid-liquid powered aircraft. Compared with solid and liquid propellant rockets, the advantage of solid-liquid powered sounding rockets is that they are easy to shut down and restart. This is due to the independent on / off control valve in the solid-liquid rocket engine, which makes the entire mixed combustion process more than liquid And the solid engine is easy to control. At the same time, solid-liquid rocket engines have strong thrust adjustment capabilities, but the stable combustion of solid-liquid hybrid rock...
