LIQUID-PROPELLANT ENGINE CHAMBER Russian patent published in 2010 - IPC F02K9/64 

FIELD: engines and pumps.

SUBSTANCE: invention refers to rocket engineering and namely to engine building industry, and can be used during development of chambers of liquid propellant engines (LPE). Chamber of liquid-propellant engine includes a mixing head, internal shaped cover on external surface of which there made are ribs of cooling circuit, external shaped cover installed on internal one and attached to it by means of soldering along tops of ribs of cooling circuit. On top 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. For improving stability of the cover, blades attach the tops of two adjacent ribs to each other; blades attach the tops of all ribs to each other so that common annular surface appears.

EFFECT: increasing stability of internal cover of combustion chamber.
