Compressed air jet pump for feeding fuel to liquid fuel rocket engine, has compressed air container that supplies compressed air into combustion chamber through two compressed air pipes

摘要

The compressed air jet pump has a combustion chamber (5) comprising two intake ports (6,7) to which oxidizer and fuel tanks (3,4) are connected through two pipes (1,2) respectively. The intake ports in combustion chamber are tapered slightly such that diameter of intake ports in combustion chamber is smaller than that of pipes. A compressed air container (8) is arranged infront of the combustion chamber so as to supply compressed air of 100bar pressure into combustion chamber through two compressed air pipes (10,12) whose diameter is smaller than that of pipes.
