Air flue mid-set type solid micro-thruster

Abstract

The invention provides an air flue mid-set type solid micro-thruster. The air flue mid-set type solid micro-thruster is characterized by comprising a laser, a lens, a combustion chamber, a heat insulation layer, a powder charge, a supporting pipe and a spraying pipe; the laser, the lens, the heat insulation layer and the spraying pipe are sequentially fixedly connected with a radius-matched innerhole in the combustion chamber from left to right; the powder charge is fixedly connected with the interior of an inner hole of the heat insulation layer; the supporting pipe is arranged in an inner hole of the powder charge to form an air channel; and the length of the part, close to one end of the spraying pipe, of the supporting pipe is greater than the length of the powder charge, and the exposed part is fixedly connected with an inner hole of the spraying pipe and communicates with an air flue of the spraying pipe. Through coaxial arrangement of the combustion chamber, the spraying pipe,the powder charge and the laser, a gas channel is arranged in the center of the powder charge, the structure is compact, and the size is small; and the laser irradiates the powder charge so that the powder charge can combust, and the micro-thruster is controllable in work.

Description

technical field [0001] The invention relates to the field of space propulsion, in particular to an airway mid-mounted solid micro thruster. Background technique [0002] Almost all micro-satellites currently developed are not equipped with a propulsion system, or have extremely limited maneuverability. Without a micro-propulsion system, the perturbation of the natural environment may cause the satellite to deviate from the orbit and fail, and the opening and closing of solar panels may affect the satellite. Attitude and antenna make it impossible to obtain and send data, etc., but the volume and mass of the traditional propulsion system are relatively large, which is not suitable for the use of micro-satellites; most of the solid micro-thrusters currently studied are L-shaped structures, that is, the nozzle axis and The direction of the gas is vertical, so the structure of this thruster is not compact enough, it takes up a lot of space, and it is not suitable for the propuls...
