Abstract: PURPOSE:To obtain an ejector for a rocket engine which can keep highly efficient combustion with a widely variable air-fuel mixture without enlarging a capacity of a burner. CONSTITUTION:An outlet of a gas propellant ejector 11 has a tapered inside which contracts on an axis of a liquid propellant ejector 12. The gas propellant is struck against the liquid propellant ejected from the liquid propellant ejector 12. The gas propellant, entering the liquid propellant, changed into bubbles. The liquid propellant is further atomized in an expansion process in a burner 2 for easy combustion.
