LIQUID-PROPELLANT ENGINE COMBUSTION CHAMBER ATOMISER HEAD Russian patent published in 2014 - IPC F02K9/52 

FIELD: engines and pumps.

SUBSTANCE: proposed atomiser head has case and fire bottom with nozzles fitted thereat. Said nozzles have central tangential and shaped channels to communicate the cavities of components with combustion chamber. End face of outlet cross-section of atomiser central channel diverging part is located ahead of atomiser tangential channel orifices. Note here that ledge h between central and tangential channels does not exceed 20% of d where d is the atomiser tangential channel diameter.

EFFECT: higher combustion chamber efficiency and specific thrust pulse.
