A Solid Micro Thruster Array Structure for Test

Abstract

A solid micro-thruster array structure for experiments comprises an ignition circuit layer, an ignition powder layer, a combustor layer and a spraying pipe layer, wherein the ignition circuit layer is located on the bottommost layer and is an array of M rows and N columns composed of M*N ignition circuits, M and N are positive integers and no less than two; the ignition powder layer is arranged above the ignition circuit layer and comprises M*N ignition powder chambers; each ignition powder chamber corresponds to one ignition circuit and is filled with gunpowder; the combustor layer is arranged above the ignition powder layer and comprises M*N combustors; each combustor corresponds to one ignition powder chamber and is filled with solid propellants; the spraying pipe layer is arranged above the combustor layer and comprises M*N spraying pipes; each spraying pipe corresponds to one combustor. The solid micro-thruster array structure for experiments can be applied to development of solid micro-thruster arrays, and research such as small-critical dimension propelling, micro-scale combustion, micro flow and control systems of micro-thrusters.

Description

technical field [0001] The invention relates to a solid micro-thruster array structure, which can be applied to the development of solid micro-thruster arrays, and can be used in the research of micro-thruster small critical size propulsion, micro-scale combustion, micro-flow, control systems, etc., which can greatly reduce development costs, development cycle, etc. Background technique [0002] In recent years, with the development of micro-nano, microelectronics and other technologies, micro-nano satellites are becoming one of the most active research directions in the aerospace field with a new concept and new design ideas.

AI Technical Summary

Problems solved by technology

[0004] At present, various research institutions at home and abroad are mainly focusing on the research on the structural design, performance test, simulation analysis, single thruster thrust test and other aspects of the small-scale thruster array. Although the United States proposed the concept of mega-units, the existing literature There is no relevant research on thruster array performance test and ignition test

The disadvantage of the array structure at this stage is that it cannot be realized quickly, and it is processed by silicon-based MEMS technology, which is not conducive to large-scale experiments.

In addition, the ignition circuit adopts the method of controlling each thruster separately, which is not conducive to the realization of scale expansion
