LIQUID-PROPELLANT ROCKET ENGINE CHAMBER MIXING HEAD Russian patent published in 2008 - IPC F02K9/52 

FIELD: engines and pumps.

SUBSTANCE: invention relates to area of power plants, in particular, to devices for mixing and dispersing fuel components and may be used in designing mixing heads of the liquid-propellant rocket engines (LPRE). The LPRE chamber mixing head incorporates an interconnected fuel feed and oxidiser units, atomisers with oxidiser and fuel feed channels arranged in the units on concentric circumferences to allow communication between units spaces and combustion chamber. The oxidiser unit peripheral area has an additional space to separate a part of peripheral atomisers from atomisers of the central area, while the channels to feed oxidiser into the combustion chamber from this space are arranged on the atomisers casings located in the said space. Here, the mixing head accommodates an oxidiser additional manifold to feed the said oxidiser into the aforesaid space.

EFFECT: expanded performances of the device by separating the feed of oxidiser in peripheral and central atomisers.
