COAXIAL SPRAY ATOMISER Russian patent published in 2014 - IPC F02K9/52 F02K9/60 

FIELD: power industry.

SUBSTANCE: invention can be used at designing of atomisers and mixing heads of liquid-propellant engines. A coaxial spray atomiser includes a housing with a hollow tip, in the outlet part of which there are radially located slots made in the form of alternating projections and cavities, and attaching an oxidiser cavity to a combustion zone, a bushing enclosing the tip with a gap and attaching the cavity of the first combustible to the combustion zone. Radially located slots are made so that perimetre of a central part of the jet, which is restricted with generatrixes of beams, is not more than 3s, and beam length is 2.3…2.5s, where s - beam thickness; with that, the number of beams is equal to three; in the bushing between the tip projections there are the channels, the outlet part of which opens to the combustion zone, and the inlet one is connected to the cavity of the second combustible.

EFFECT: increasing completeness of mixture formation.
