Embodiment Construction

[0009] figure 1 and figure 2 It is a schematic diagram of the structure of this three-stage accelerated helicon wave plasma propulsion device. It can be seen from the figure that its shoji-type antenna 101 is connected to a radio frequency power source and fixed around the outside of the discharge chamber 102 . Both the shoji type antenna 101 and the discharge chamber 102 are fixed inside the sleeve 104 . The electromagnetic coil i-103 is regularly and orderly fixed on the outer peripheral surface of the sleeve 104 . The electromagnetic coil i-103 is surrounded by a hollow copper tube. The working gas comes out of the gas storage chamber and then enters the discharge chamber 102 through the hollow copper tube. This process can not only cool the copper tube, but also preheat the working gas. The sleeve 104 is made of carbon fiber composite material. The discharge chamber 102 is used to shield the plasma in a certain area to prevent the equipment from being corroded. The sh...

Abstract

The invention discloses a three-level acceleration type spiral plasma propulsion device. The three-level acceleration type spiral wave plasma propulsion device is characterized in that an antenna is connected with an RF (Radio Frequency) power source, the antenna and a discharge chamber are fixedly arranged in a sleeve, and an electromagnetic coil is fixedly arranged on the outer circumferential surface of the sleeve in a surrounding way; the rear part of the discharge chamber is provided with a rotating electric field ion acceleration system, and the rotating electric field ion acceleration system comprises four graphite electrodes which are uniformly and symmetrically arranged on the outer circumferential surface of the sleeve; the tail end of the rotating electric field ion acceleration system is provided with an electromagnetic spray pipe ion acceleration system, and the electromagnetic spray pipe ion acceleration system comprises a conical expanding spray pipe of which one end is connected with the tail part of the discharge chamber, and the electromagnetic coil. According to the three-level acceleration type spiral plasma propulsion device disclosed by the invention, the rotating electric field acceleration system is adopted for carrying out secondary acceleration on a plasma, acceleration is further carried out through the electromagnetic spray pipe, and a three-level acceleration effect is formed, thus the thrust is generated by efficiently accelerating ions, the work of a propulsor under high power can be realized, the reliable performance of high ion ejecting speed and high propulsion capacity can be realized, wide application prospect is obtained, and a high-performance power platform can be provided for future space technology development.

Description

technical field [0001] The invention relates to the field of space propulsion technology. Background technique [0002] At present, with the increasingly active human space activities and deep space exploration activities, aerospace technology has also undergone tremendous and rapid development, and the range of human activities in space has become wider and wider, which puts higher demands on spacecraft propulsion systems. indicator requirements. The space propulsion system provides power for the spacecraft during its spaceflight phase for attitude control, north-south position keeping, orbital maneuvering and deorbiting. Space propulsion technology can generally be divided into chemical propulsion and electric propulsion, as well as some other propulsion technologies, such as nuclear energy propulsion, solar sail propulsion and other technologies. Compared with chemical propulsion, electric propulsion has the characteristics of high specific impulse, long life, small thr...
