PULSED DETONATION ROCKET ENGINE Russian patent published in 2018 - IPC F02K7/04 F03H1/00 

FIELD: military equipment.

SUBSTANCE: invention relates to rocket engineering and is intended to design pulsed rocket engines for spacecraft orientation systems and launch from the surface and landing on low-gravity planets, for example, the Moon. Pulsed detonation rocket engine, in which the supply and ignition system is made in the form of a transparent dielectric tube filled with an inert gas, on the ends of which an anode and a cathode are mounted, and the working body is made in the form of a cylindrical truncated cone made of light-absorbing material, whose wide base faces a supersonic nozzle. Said dielectric transparent tube is installed along the axis of symmetry of the cylindrical truncated cone.

EFFECT: invention facilitates the initiation of discharge, increases the flow rate of the working fluid, and increases the fraction of the burned working fluid, which enables to obtain supersonic velocities at the nozzle outlet, and simplification of the working fluid ignition and supply system.
