CHAMBER OF LIQUID-PROPELLANT ENGINE OR GAS GENERATOR Russian patent published in 2015 - IPC F02K9/95 

FIELD: engines and pumps.

SUBSTANCE: invention relates to rocket production, namely to a chamber of a liquid-propellant engine (LPE) or a gas generator with laser ignition of fuel components. A chamber of LPE or the gas generator includes a pressure vessel, a mixing head with oxidiser and fuel injectors fixed at a flame bottom, a combustion chamber with a nozzle; with that, the chamber housing has an external pressure shell and an internal fire wall, between which a regenerative cooling circuit is located, and a laser device for ignition of fuel components; with that, the laser device includes a nozzle tightly installed in a hole made in the wall of the pressure vessel on its side surface and a laser plug; with that, an attachment point of the nozzle to the housing is chosen so that a laser beam leaving it can be focused in a reverse-flow area and near the internal fire wall, inside which a nozzle is installed; with that, the reverse-flow area is located at minimum possible distance from the flame bottom of the mixing head and from the internal fire wall, which is determined experimentally at model setups.

EFFECT: invention provides improvement of reliability and repetition of ignition of a fuel mix in a chamber of an engine or a gas generator.
