ABSTRACT:
A helicopter includes a rotor tip jet engine which combines ram compression and centrifugal compression to increase the thrust. A first flow of fuel is dispersed in the ram air and is carried into a combustion area of the engine. A separate flow of fuel is injected into the centrifugally compressed air before the fuel air mixture enters the combustion area. For helicopters and other applications, the ram jet engine combines ram air and a separate mass of compressed air which is directed into the combustion area for increased thrust. A regulator or control mechanism is also provided for regulating the quantity of compressed air which is added. The regulator or control mechanism may also be used to cut off or stop the addition of the separate mass of compressed air.
