Abstract

1324240 Gas turbine ducted fan engines DEFENCE SECRETARY OF STATE FOR 26 April 1971 [15 April 1970] 17873/70 Headings F1G F1J and FIT A ducted fan 10 has tip turbine impulse blades 18 driven by combustion gases directed through an inlet duct 24 to a part-annulus of convergentdivergent nozzles 20, the gases leaving blades 18 being re-directed through transfer duct 25 to a further part-annulus 23 of nozzles for a second pass through blades 18. The gases finally exhaust from the latter through an annular duct 26. Further part-annuli of nozzles and corresponding transfer ducting are provided. In a modification the transfer ducting etc. is arranged so that the first and second passes through blades 18 are in opposite directions. The fan blades 16 are carried by a shaft 15 mounted in a bearing 14 contained within housing 13. The latter is supported by radial struts 12 from annular outer casing 11. The fan may be used for forward propulsion or lift of an aircraft.
