Abstract

The invention relates to a testing device for testing ignition combustion characteristics and propulsive performance and is to disclose a device for testing ignition combustion characteristics and propulsive performance of a solid fuel micro-thruster. The device comprises a laser, a reactor, a vacuum pump, a high-speed camera, a high-speed temperature detector, a fiber optic spectrometer, a data acquisition card, a synchronous trigger switch and a computer, wherein the reactor comprises a pressure-resistant glass cover, a micro-thruster fixing rack, a sealing ring, a pedestal, a pressure gauge and a high-sensitivity pressure sensor. The device is characterized in that a propulsive agent in the thruster is ignited by a laser ignition method; the ignition energy, the ignition temperature and the heating rate are basically the same as these of the actual resistance wire, but the cost is greatly reduced, the process is greatly simplified, and the working stability is better; thus the testing device is very suitable for test and research in a laboratory.

Description

technical field [0001] The invention relates to a test device for testing ignition combustion characteristics and propulsion performance, in particular to a device for testing ignition combustion characteristics and propulsion performance of solid fuel micro-propellers. Background technique [0002] Due to a series of advantages such as low launch cost, good stability and flexibility, and suitability for remote and deep space missions, the miniaturization of spacecraft has become a development trend in the aerospace industry. With the miniaturization of spacecraft, the original propulsion system is difficult to meet the needs of small spacecraft. Therefore, the research on micro-propulsion is very urgent and important. Among all kinds of micro-propellers, MEMS-based solid-fuel propellers have become a research hotspot because of their simple and compact structure, no moving parts, and low possibility of leakage. The performance research of MEMS-based solid fuel propulsion i...
