Abstract

The invention relates to an ignition system for a solid micro-thruster array, and is particularly suitable for a large-scale solid micro-thruster array. Aiming at the problems of small scale of the conventional controllable thruster array and large wiring difficulty of a large-scale independent type ignition circuit, the scale of the micro-thruster array is actually realized by using an array ignition circuit and ignition control over the thruster combination, which meets attitude and orbit control requirements, of the thruster array is realized by designing the matched control circuit and driving circuit. Due to the adoption of the system design, the required relative hardware such as wires and the like is reduced, so that the ignition system is controllable and simple, greatly reduces the complexity of a circuit and improves the stability and reliability of ignition.

Description

technical field [0001] The invention relates to an ignition system of a miniature solid thruster array, which is especially suitable for a large-scale miniature solid thruster array. Background technique [0002] With the development and application of micro-satellites, it also poses challenges to its high-precision attitude and orbit control, which requires actuators with small mass and volume, high integration, low power consumption, and high reliability to provide small and precise impulses , while the micro-solid thruster array can meet the requirements of the micro-satellite attitude and orbit control system. The micro solid thruster array can integrate high-density micro thrusters. Each thruster unit generates a tiny impulse, which can realize any combination of ignition and variable thrust control. The outstanding advantage of this thruster is that it can be applied to kilograms Pico-satellite or nano-satellite is a new type of satellite control power device. [000...
