Abstract
A jet pump comprising a jet nozzle for accelerating a propellant. The jet nozzle has a convergent inlet part and an outlet part connected to the convergent inlet part. The outlet comprises an inner wall diverging at an opening angle. The opening angle is designed such that a propellant flowing through the outlet part at subsonic speed is detached from the inner wall and a propellant flowing through the outlet part at supersonic speed is guided by the inner wall. An automatic, cost-effective and simple changeover of the jet pump to different pressure ratios is hence provided.
Claims6
A jet pump comprising a jet nozzle for accelerating a propellant, wherein the jet nozzle has a convergent inlet portion and an outlet portion which is connected to the convergent inlet portion, wherein the outlet portion comprises an inner space which is surrounded by an inner wall and which diverges at an opening angle, wherein the opening angle is constructed in such a manner that a propellant which flows through the outlet portion at subsonic speed is released from the inner wall and a propellant which flows through the outlet portion at supersonic speed is guided by the inner wall.
