Example Embodiment
[0021] This embodiment is a miniature solid rocket motor. The structure of the micro solid rocket motor consists of four parts, including: nozzle layer 1, ignition resistance wire 2, combustion chamber layer 3 and end cap layer 4; among them, nozzle layer 1 and combustion chamber layer 3 are glued together; ignition The resistance wire 2 and the nozzle layer are bonded together; the combustion chamber layer 3 and the end cover layer 4 are bonded together. The nozzle layer, the combustion chamber layer and the end cap layer are all made of silicon wafers through MEMS technology; several miniature solid rocket motors are integrated on a chip.
[0022] Such as figure 1 As shown, the ignition resistance wire 2 of the miniature solid rocket motor of the present invention is inlaid in a position corresponding to the diameter of the rear end of the nozzle layer 1 with fine grooves and the front end of the combustion chamber layer 3, and the ignition resistance wire and the nozzle The c...
