Abstract

1,157,930. Gas turbine ducted fan engines. ROLLS-ROYCE Ltd. Nov. 8, 1967 [Dec.28, 1966], No. 57984/ 66. Addition to 1,127, 660. Headings FIG, F1J and F1T. The invention relates to a gas turbine ducted fan engine comprising a gas turbine type gas generator, a duct arranged to receive gases from the gas generator a free turbine mounted in the duct to be driven by the exhaust gases, the turbine having at least one rotor stage located in a substantially radially extending part of the duct, and a fan coaxial with the gas generator and driven by the free turbine, at least a portion of the duct being porous, there being means for passing cooling-gas through the porous portion and into the duct. The invention is described with reference to an engine which comprises a gas turbine type gas generator 5 the gases from which discharge through duct 6 and are directed by inlet guide vanes 10 on to a three stage outward radial flow power turbine 11. The turbine 11 is connected to drive a fan 13 located in a duct 4 defined between inner and outer casings 3, 2. The part 14 of the gas duct 6 is formed of porous material and a supply of air under pressure is taken from a compressor of the gas turbine gas generator 5 and supplied to the porous wall, the air passing through the wall into the gas flowing within the duct. The inner wall of the duct 6 may be also formed of porous material. The gas turbine type gas generator comprises low pressure and high-pressure compressor and turbine assemblies and the cooling air may be taken from the HP compressor.
