LIQUID-PROPELLANT ROCKET ENGINE COMBUSTION CHAMBER MIXING HEAD Russian patent published in 2001 - IPC

FIELD: aeronautical engineering. SUBSTANCE: mixing head of combustion chamber has housing with bottom and fitted-on bushings whose clearances form ring channels for delivery of liquid and gaseous components. Proposed mixing head has mixing members secured on outlet ends of bushings. Each mixing member consists of two concentrically interconnected rings. Two screw cuts forming a collector in between are made on one of inner surfaces of rings. Collector is connected by inclined holes with channels to deliver gaseous component. Inclined holes are made on opposite walls of gas channel being uniformly displaced relative to each other. Throttling holes are made at inlet of gaseous component channels. Such design of mixing head provides complete combustion of fuel components in chamber of liquid-propellant rocket engine at stable combustion process at all loads and stability of construction to thermal action of fuel combustion products. EFFECT: improved conditions of fuel combustion. 4 dwg
