ELECTROJET PROPULSION SYSTEM Russian patent published in 2024 - IPC F03H1/00 

FIELD: space engineering.

SUBSTANCE: invention relates to electric rocket engines with inductive plasma source using outboard atmosphere as working medium. Electrojet propulsion system comprises a gas-collecting device, a heat-stabilizing chamber, hermetically connected to the gas collecting device and a storage tank, gas-discharge chamber installed coaxially to gas collecting device. Gas-discharge chamber is a hollow cylinder, the walls of which are made of radiotransparent dielectric material. One end of the gas-discharge chamber is connected through gas lines, including shutoff and control valves, with a storage tank, and the other is openly communicated with the environment. Working medium ionization and acceleration system includes an antenna located coaxially to the gas-discharge chamber, a high-frequency generator, matching unit of high-frequency generator and antenna, constants or electromagnets and power supply. Outboard gas collection device is adjustable and is made in the form of a structure of variable cross section and/or variable opening angle. Thermostabilizing chamber is tightly connected to the storage tank by gas mains through a blower and a device which prevents gas backflow.

EFFECT: higher spacecraft maneuverability, possibility of its operation in low orbit of atmosphere celestial bodies, higher efficiency.
