HYBRID WAVE PLASMA ENGINE FOR LOW ORBIT SPACE VEHICLE Russian patent published in 2022 - IPC F03H1/00 H05H1/54 

FIELD: space technology.

SUBSTANCE: invention relates to space technology, in particular to electric propulsion systems with an electric rocket engine (ERE). A hybrid wave plasma engine for a low-orbit spacecraft contains a gas-discharge chamber made open to the external atmosphere from two opposite ends with the possibility of forming two thrust vectors opposite to each other in direction, an antenna, an HF generator module, which is electrically connected to the antenna, magnetic systems, located one at each of the opposite ends of the gas discharge chamber, having electrical communication lines with power sources of magnetic systems, a storage and supply system of the working fluid connected to the gas discharge chamber by means of two radial gas inlets, hermetically connected to the gas discharge chamber in two places, located to the locations of the magnetic systems. A material with a low work function of electrons is applied to the inner surface of the gas-discharge chamber. The antenna is located on the outer surface of the gas-discharge chamber in the center and on its outer side is surrounded by a ring of dielectric material, covered from its outer side with a layer of an electric current-conducting material. The engine contains a magnetic attitude control system of a low-orbit spacecraft, consisting of three current coils directed along three orthogonal axes associated with the coordinate system of a low-orbit spacecraft, which, when interacting with the earth's magnetic field, lead to the emergence of controlled magnetic moments, with the help of which it is possible to change the orientation low-orbit spacecraft.

EFFECT: implementation of the invention provides a reduction in the mass and dimensions of the engine, an increase in specific thrust and specific impulse of the engine per unit of power consumption.
