Abstract

The application discloses a turbocharging-based air-breathing electric propulsion device. The electric propulsion device includes a carbon-carbon composite shell forming a muzzle cavity, a ceramic shell forming an acceleration cavity, a plasma source located in the muzzle cavity, a turbine installed at the front end of the carbon-carbon composite shell, and several uniformly wound ceramic shells. electromagnetic coil. This application realizes the high-speed discharge of neutral gas, avoids the loss of ionization energy of neutral atmosphere, greatly improves the energy utilization efficiency of electric propulsion device, and overcomes the restriction of propellant working medium type at the same time, broadens the application of thruster On the other hand, it also improves the reliability of the electric propulsion device and the effectiveness of neutral gas acceleration, and the discharged neutral plume will not affect the aircraft, improving the safety of the spacecraft.

Description

technical field [0001] The present application relates to the technical field of aerospace electric propulsion, in particular, to a turbocharged-based air-breathing electric propulsion device. Background technique [0002] Electric propulsion uses electric energy to ionize the working fluid to generate plasma, and accelerates the plasma to be discharged at high speed through electrostatic field or electromagnetic field to generate reverse thrust. Due to the need to overcome different types of working fluid and ionization energy loss (gas ionization is the main energy loss mechanism, for example, the ionization energy lost by generating a xenon ion is 50eV-100ev), resulting in low efficiency of electric propulsion, which restricts the substantial improvement of thruster performance . At the same time, the current electric propulsion mainly adopts the method of electrostatic field acceleration, and there are electrodes (electrode corrosion), which makes it impossible to use v...
