Abstract
668,863. Gas turbine plant. BRISTOL AEROPLANE CO., Ltd. May 22, 1950. [May 25, 1949] No. 14036/49. Class 110(iii). [Also in Groups XXV and XXXIII] A gas turbine engine installation comprises a ram-air inlet leading to the compressor of the engine, a debris guard at the air inlet, an auxiliary air inlet at a region normally free of ice formation, a conduit to convey air to the compressor from the auxiliary inlet over the engine whereby it is heated and closure means for the auxiliary air inlet which automatically open when the guard becomes blocked. A propeller turbine engine 5 has a normal air inlet formed by a duct 14 leading from a forwardlyfacing inlet 16 and an auxiliary inlet formed by openings in the rear end of the engine cowling, the space inside the cowling around the engine and an annular passage 19. The front end of tne passage 19 which is formed between the cowling skin and an inner wall 20 carried by the engine connects with the duct 14 downstream of a guard grid 18 and the rear end is closed by a plurality of spring-loaded flaps 22. The openings in the rear end of the cowling are closed by spring-loaded shutters 23. The arrangement is such that when the grid 18 is blocked by ice, the suction of the compressor 9 opens both the shutters 23 and flaps 22 and air flows over the'engine, where it is heated, into the compressor. In normal operation, air flows through the duct 14 into the compressor. Part of this air flows through the passage 19, through holes in flaps 22, Fig. 2, into the engine space, and is discharged from this space around the tail pipe 12. Several rows of shutters 23 may be provided and the strength of the shutter springs so selected that the shutters open in predetermined succession as the suction effect in duct 14 increases. The flaps 22 are pivoted on the wall 20 by means of a bell-crank 26, one arm of which is connected to a plunger 27. The plunger is loaded by a spring 28 mounted between concentric sleeves 29, 30. Specification 592,091 is referred to in the Provisional Specification. Reference has been directed by the Comptroller to Specifications 579,657, [Group XXXIII], and 692,091.
