Abstract

1,187,171. Gas turbine engines - starting. GENERAL ELECTRIC CO. March 13, 1968 [April 3, 1967], No. 12215/68. Heading F1G. The invention relates to a fluid impingement type starting system for a gas turbine engine, the starting system comprising a nozzle ring which is located downstream of a ring of turbine stator blades and upstream of a ring of turbine rotor blades, there being nozzle outlets in the nozzle ring through which starting fluid is directed on to the turbine rotor blades. The engine shown comprises a two stage turbine 12 comprising second stage nozzle guide vanes 18 and second stage rotor blades 13 which are mounted on the rotor 14. A starter nozzle ring 22 is located between the stator blade assembly 18 and the rotor blade assembly, 13, the ring 22 being of channel section and being formed in its base portion 24 with nozzle outlets 21 through which starting fluid may be discharged on to the rotor blades 13 to start the engine. The turbine stator structure comprises parts 2, 3, 4 secured together, the part 3 being formed with a starting fluid inlet duct 15 also with a duct part 17 through which starting fluid can pass to the nozzle ring member 22. The ring member 22 is supported in a "floating" manner as follows: the upstream flange 32 of the member bears against a radially inwardly projecting flange 27 of the stator member 3, while the downstream flange 33 of the ring member bears against a flange of the ring member 28 which is itself secured between the stator members 3, 4, the flange of the ring member 28 carrying projecting pins 29 which engage within radial slots 30 formed in the downstream flange 33 of the ring member 22 is located with provision for thermal radial expansion. The stator members 2, 3, 4 are onepiece, undivided members which allow the starter ring member to be assembled in an axial manner.
