Abstract

1362799 Gas turbine engines DEFENCE SECRETARY OF STATE FOR 13 Jan 1972 [2 Feb 1971] 3654/71 Heading F1G A gas turbine engine comprises at least two compressors in flow series, each compressor being driven by a turbine through a respective shaft, a bleed duct being located at the downstream end of the upstream compressor, the upstream compressor and the associated driving turbine being provided with flow and speed regulating means so that the quantity of air flowing through the bleed duct can be varied as desired. The engine shown is a gas turbine ducted fan engine which comprises a fan 12 and L P compressor 14 mounted on shaft 16 and driven by L P turbine 18, I P compressor 20 mounted on shaft 24 and driven by I P turbine 28, H P compressor 22 mounted on shaft 26 and driven by H P turbine 30; also combustion equipment 32. Air is bled from the L P compressor 14 through duct 36 and is utilised for example for boundary layer control. The L P compressor is provided with variable stator vanes (not shown) and the L P turbine is provided with variable inlet guide vanes (not shown). In a second embodiment, the fan, L P compressor and H P compressor are each driven by separate turbines.
