<p>1, 056, 338. Gas turbine engines. C. A, V. Ltd. June 8, 1965 [June 11, 1964], No. 19511/64. Heading F1G. The invention relates to a gas turbine type gas generator for the supply of hot gases such as for use in crop drying plants and aircraft engine heaters. The gas generator comprises a shaft 11 rotatably mounted within a body part 10, the impeller 20 of a centrifugal compressor being mounted at one end of the shaft and the rotor 14 of a radial inward flow turbine at the other end The compressor has an axial air inlet 24 and a tangential outlet 23 from which air passes to a combustion chamber 26, Fig. 1 (not shown), combustion gases passing through a tangential inlet 17 to the turbine 14 and discharging therefrom to a point of use through the axial outlet 18. The shaft 11 is formed with opposite-hand screw threads 12 which constitute a fuel pump having inlet ducts 32 and an outlet duct 33. Fuel is supplied from a tank to the inlet 29a, and the fuel discharging from the outlet 33 passes through line 35 to the spray nozzle in the combustion chamber. The crests of the screw threads 12 serve as a shaft bearing. The shaft is located against axial movement by means of a pair of thrust blocks 13. Sealing plates 19 and 25 are secured to the body part 10 adjacent the turbine and compressor respectively.</p> |
