A micro-thrust generating device using a capsule-type fuel unit and its operating method

Abstract

The invention discloses the technical field of a spacecraft propulsion technology and an orbital attitude control, and discloses a miniature thrust generation device with capsule type fuel units and an operation method thereof. The miniature thrust generation device comprises one or more miniature thrust generation units and a fuel unit storage and conveying device, combustion rooms of the miniature thrust generation units can be cleared and filled with the fuel units, and therefore each miniature thrust generation unit can output thrust pulses multiple times, and since the capsule type fuel units are provided with ignition circuit assemblies, the problem of repeated ignition of the miniature thrust generation units is solved more reliably. The miniature thrust generation device further comprises a control computer system which is used for completing the operations. According to the device and the operation method thereof, the technology of the miniature thrust device can be used for the field of a space technology more widely and economically, and a control force is provided for a miniature spacecraft for a longer term.

Description

technical field [0001] The invention belongs to the technical field of spacecraft propulsion technology and orbit and attitude control, and belongs to a solid fuel micro-thrust generating device suitable for orbit and attitude control of tiny spacecraft. Background technique [0002] A spacecraft refers to an aircraft that operates in space and performs specific tasks such as exploration, communication, and experiments. Micro spacecraft has many advantages such as low cost, short development cycle, flexible launch, high functional density, etc., and has great development potential and application prospects. At present, the global micro-spacecraft industry is showing an explosive development trend. In order to make full use of the huge advantages of micro-spacecraft, the demand for developing thrust generators suitable for micro-spacecraft orbit and attitude control systems is increasing. Solid fuel micro-thrust generators can well meet this requirement and have received a l...

Problems solved by technology

If the mechanism is relatively complex, it is prone to failure; although the ignition device is arranged close to the bottom of the combustion chamber, which can reduce the impact of combustion products, it is still easy to be damaged, resulting in failure of the thrust generating unit; in order to offset the torque generated by the rotation of the disc, a The method of rotating two coaxial disks at the same time, with the same angular rate change law, in the opposite direction by the same angle, which increases the complexity of the spacecraft control system algorithm
