Abstract
588,918. Gas turbines. POWER JETS, Ltd., and McLEOD, R. C. July 2, 1942, No. 9175. [Class 110 (iii)] A jet-augmenter comprises a single rotor carrying two or more rows of two-tier axial flow bladings, the inner bladings are driven by the turbine exhaust and the outer bladings energize extra air for the jet. The rotor may comprise two discs 15, 16 keyed to a shaft 14 mounted in bearings 11, 12. The discs carry inner rings 15A, 16A which overlap with an interference fit and outer rings 15B, 16B which abut. The space between the rings is divided by a disc 17. The turbine blades 18, 19 cooperate with stationary blades 8, 21 and 22 and the compressor blades 18A, 19A with. stationary blades 21A, 22A. The inner structure is supported by three or more tubular members 9 which pass through streamlined fairings 9A. Cooling air is picked up by parts 9B, passes through members 9 to the hollow of the shaft 14, over the up-stream face of disc 16, through holes 16C, holes in the rings 16A. 15A and holes 15C, over the down-stream side of-disc 15 and out through pipes 23c. Some air passes through holes 16D, 15D and a gap at 23D into the turbine stream. Oil is supplied to the bearings by pipes 25. The final jet-pipe may have an axially movable obturator. Specifications 456,980, 471,368, [both in Group XXXIII], and 583,111 are referred to.
