Abstract

1,147,730. Gas turbine plant; axial flow compressors; turbines. ROLLS-ROYCE Ltd. Dec.19, 1967, No.57669/67. Headings F1C, F1G and F1T. [Also in Division H2] A gas turbine engine having two relatively rotatable members at least one of which is drivingly connected to, or forms part of, a compressor of the engine includes starting apparatus comprising an induction motor of which the energizable part is secured to one of the members and the other part is formed by an electrically continuous unwound metal member secured to, or forming at least part of, the other member. The term "unwound" does not include motors of the squirrel-cage type. In Fig. 1 the drivable part of the induction motor 40 comprises an aluminium or aluminium alloy disc 45 mounted on the high pressure compressor shaft 16 of a gas turbine by-pass engine. The energizable part 42 of the motor comprises a fixed annular magnet structure 46 on either side of the disc 45, each structure 46 supporting laminated polepieces 50 carrying windings 52 connected to a multi-phase A. C. supply. The structure 46 is supported by guide vanes 26 of the high pressure compressor 14. In a modification, Fig. 2 (not shown), the fixed structure of the motor is similar to that shown in Fig. 1 but the drivable part comprises an annular radially extending aluminium ring (60) bonded to a face (62) of a rotor disc 30, the latter being of titanium. In a further modification, Fig.3, the radially extending ring (60) is replaced by an axially extending ring 70. Fig.4 (not shown), illustrates a slight modification of Fig. 3. When the compressor rotor is made from aluminium or an alloy thereof, the drivable part of the induction motor can be formed by the rotor itself without the addition of discs or rings such as 45 or 70. In further modifications, the energizable part of the motor can be secured to a rotatable part of the engine, or the motor can be connected within a compressor driving turbine or between contra-rotating compressors of an engine. The motor may function as a generator when normal operating speed of the engine has been reached.
