Embodiment Construction
[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] 1. Overall and basic unit structure
[0032] figure 2 Shown is the overall structure of the thruster, which is formed by bonding the upper silicon wafer 1 and the lower silicon wafer 2. It is a periodic array of a series of basic propulsion units 3. The size of the array can be changed according to the actual use requirements. Craft level limitation. In order to prevent the chain explosion of adjacent units from damaging the entire propeller due to the explosion of one unit, the grouping array layout of propulsion units is adopted.
[0033] Such as image 3 As shown, the upper part 4 of the basic propulsion unit 3 integrates the combustion chamber, the ignition charge chamber and the nozzle. The nozzles are uniformly distributed around the combustion chamber and are rotationally symmetrical with respect to the central axis of the combustion chamber. The ...
