LOW-THRUST LIQUID-PROPELLANT ENGINE CHAMBER Russian patent published in 2020 - IPC F02K9/52 

FIELD: machine building.

SUBSTANCE: invention relates to low-thrust liquid-propellant engine chamber. Low-thrust liquid-propellant engine chamber comprising a combustion chamber, a nozzle and a mixing head, with a two-component centrifugal nozzle arranged on its axis, with corresponding fuel components at inlet of tangential channels of nozzles of external and internal centrifugal nozzles, wherein in the manifold of the external nozzle on its outer surface in the zone of input tangential channels there is a pressure tight ring installed, which forms an additional header, which is connected to the main header by tangential channels, located in cavity shifted relative to plane of inlet channels of external centrifugal nozzle, and directed to side coinciding with direction of swirling tangential channels of external nozzle. Additional collector is made in the form of an annular groove on the outer surface of the external centrifugal nozzle in the zone of tangential channels. Collector of inner nozzle is provided with axial supply of fuel component. Collector of external nozzle is additionally communicated with jet nozzles arranged on periphery of mixing head or periphery of external nozzle. Collector of external nozzle is communicated with manifold of jet nozzles via annular slotted channel.

EFFECT: invention provides higher energy and dynamic characteristics of the engine.
