LIQUID-PROPELLANT ENGINE ANNULAR CHAMBER Russian patent published in 2011 - IPC F02K9/64 

FIELD: engines and pumps.

SUBSTANCE: annular chamber of liquid-propellant engine includes annular mixing head, regeneratively cooled annular combustion chamber with plate nozzle of external expansion, and shaped central body, which are formed with internal and external shaped covers attached to each other along cooling circuit ribs. On tops of ribs of cooling circuit there are blades located parallel to the slot bottom; at that, external profile of blades corresponds to internal profile of external cover. In order to increase internal cover stability, the blades attach the tops of two adjacent ribs to each other, the blades attach the tops of all ribs to each other so that common annular surface is formed, and the external profile of which is equally spaced relative to internal profile of external cover at point of contact with external surface of internal cover.

EFFECT: increasing stability of internal cover.
