IPC: F02K7/00
Filed: 1965-10-14
Abstract: 1,173,144. Gas turbine ducted for engines; axial-flow fans. ROLLS-ROYCELtd. Jan.11, 1967 [Oct.14, 1965], No.43675/65. Headings F1C; F1G and F1J. A power plant comprises a ducted fan, means to establish combustion within the duct downstream of the fan, and means for discharging fluid from some at least of the fan blades thereby to drive the fan, the fan blades being of uncambered crosssection, a virtual blade camber being formed by the blade itself and by the fluid stream discharging from the blade. The invention is shown applied as a jet propulsion engine, the duct 10 having a centre body 12 supported therein by means of struts 13. A rotor member 15 carrying fan blades 16 is rotatably supported in bearings 14 by the centre body 12. Air flows through the duct 10 as indicated by the arrow 23. The fan blades 16 are hollow to provide combustion chambers 21 having discharge nozzles 22, fuel and oxidant being supplied to distributers within the chambers 21 through ducts 17 and 18 in the fixed struts 13. The discharge of combustion gases through the nozzles 22 causes the fan blades to be driven, the fan causing an air-flow as indicated by the arrow 28. The combustion gases discharging from the nozzles 22 are arranged to provide unburned fuel, this fuel burning with the air downstream of the fan. The resulting combustion gases discharge through a propulsion nozzle at the downstream end of the duct 10. When the velocity of the engine is sufficiently great the supply of oxidant to the combustion chambers 21 may be stopped, the blades 16 acting as rotary fuel distributers. In fact the rotation of the fan may be stopped, the engine now functioning as a ram jet unit.
