COMBUSTION CHAMBER OF LOW-THRUST LIQUID-PROPELLANT ENGINE Russian patent published in 2015 - IPC F02K9/62 F02K9/52 

FIELD: engines and pumps.

SUBSTANCE: invention relates to rocket engineering, namely to arrangement of mixture formation of self-inflammable fuel components in a combustion chamber of a low-thrust liquid-propellant engine (LTLPE). A combustion chamber of LTLPE consists of a housing and a mixing head with peripheral spray nozzles coming out of an annular manifold of the first fuel component, the axes of which cross the surface of the annular conical deflector guiding the jets of the first component to the wall of the housing of the combustion chamber, and a central sprayer interconnected with the collector of the second fuel component. According to the invention, the annular collector of the first fuel component is arranged in a radial direction between the annular conical deflector and the manifold of the central sprayer, and spray nozzles of the first components on one side are directed to the surface of the conical deflector facing to the combustion chamber outlet, and on the other side to the surface of the deflector being the wall of the manifold of the second component, and spray nozzles of the second component are directed to the surface of the deflector being the wall of the collector of the first component. Surfaces of deflectors of the central sprayer are cylindrical; planes of arrangement of spray nozzles are equally spaced in an axial direction of the chamber to the distance of not less than the double sum of diameters of spray nozzles of the first and the second fuel components.

EFFECT: invention ensures increase of LTLPE economy, improvement of dynamic characteristics of the engine and LTLPE manufacturability.
