COMBINED ION ROCKET ENGINE AND CORONING ELECTRODE Russian patent published in 2021 - IPC F02K9/00 F03H1/00 

FIELD: rocket engines.

SUBSTANCE: ionic rocket engine contains a combustion chamber connected to each other and located coaxially, to which a magnetic plasma accelerator is connected, and then a supersonic gas-dynamic nozzle with converging and expanding parts, at least one igniter, and a means for creating a corona discharge. The combustion chamber contains a head with a nozzle plate for atomizing fuel components and a cylindrical part having fuel and oxidizer nozzles on the plate. The means for creating a corona discharge is made in the form of corona electrodes installed evenly between the nozzles on the plate in the inner cavity of the combustion chamber. A cylindrical permanent magnet with axial magnetization is installed in the conical body of the head. At the exit of the magnetic accelerator, an accelerating electrode is installed inside it. A neutralizer electrode is installed at the outlet end of the nozzle. The nozzle is made with a cooling gap between the "cold" and "hot" walls. The gap cavity is connected to the fuel pipe, installed concentrically to the outlet end of the nozzle, and the ignitors are aligned with the corona electrodes.

EFFECT: during operation of the proposed engine, reliable starting and controllability of thrust force and vector is ensured.
