Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 , figure 2 As shown, the gas injection and electro-spray integrated hybrid driving device includes several thruster bodies arranged in an array. Using the Cartesian three-dimensional coordinate system as a reference, the thruster body 1 is arranged in arrays in three different directions. A water inlet 2 and an injection port 3 are provided, and an injection channel is provided between the water inlet 2 and the injection port 3 in the main body of the propeller, and a resistance metal heating sheet 4 and an injection electrode 5 are bonded in the injection channel, and the injection port 3 is set. A ground electrode 6 is bonded to the end of the thruster body 1 . Wherein, the position corresponding to the heater 4 in the injection channel is coated with an insulating layer to ensure that the current passes through the heater 4 to achieve the ...

Description

technical field [0001] The invention relates to an injector, in particular to an integrated hybrid drive device for gas injection and electric injection. Background technique [0002] Miniaturization is one of the important directions of the development of modern industrial technology. Micro-electro-mechanical systems also have considerable practicability, and are widely used in aerospace, energy, biology, chemical and other technical fields. With the development of modern aerospace technology, MEMS technology has been gradually integrated into the field of aerospace technology, and the miniaturization of spacecraft has become one of the mainstream directions of technological development. The development of satellite miniaturization is expected to reduce the number of launches to reduce mission costs and greatly increase the launch rate. Launch costs for a typical interstellar mission can be as high as 30% of the overall mission cost, and these costs could be significantly...
