Abstract

921,694. Mounting gas turbine inlet casings. GENERAL ELECTRIC CO. Sept. 26, 1961 [Oct. 31, 1959], No. 34420/61. Class 110 (3). The invention relates to a method of mounting the inlet scroll of the gas turbine of a turbinedriven fan to an air-frame structure, the inlet scroll having an arcuate gas duct with an inlet opening and outlet openings along the length of the arcuate duct, the scroll being supported by the airframe structure at three spaced points including a fixed support and two movable supports which permit expansion or contraction of the scroll along axes which coincide with radial lines drawn from the fixed support as centre to the two movable supports. The turbo-fan unit 10 shown in Fig. 1 is suitable for mounting in an aircraft to give vertical lift and comprises a series of fan blades 11 with a series of turbine blades 12 mounted round the periphery thereof, combustion gases being directed on to the turbine blades through an arcuate inlet scroll 13 which comprises a combustion gas inlet 14 and two arcuate portions 15 at either side thereof. The scroll is supported at three points, 16, 19, 19, the support 16 being fixed and the supports 19 being movable along the lines 22 which pass through the point 16 and the points 19. The support 16 is shown in Figs. 2 and 3, the airframe structure being indicated at 17, this support possibly allowing a slight rocking movement. A movable support 19 is shown in Fig. 4 and comprises a ring member 21 secured to the inlet scroll 15, the member 21 being in slidable engagement with a fixed rod 20 secured to the airframe structure. An alternative arrangement comprises a link pivoted at its ends to the inlet scroll and to the airframe structure. In a further arrangement the inlet scroll is similar to that of Fig. 1, but it extends nearly along a full circle, the movable supports, such as 19, being disposed away from the ends of the arcuate portions such as 15. In a second arrangement giving full admission to the turbine, two arcuate inlet scrolls such as 13, Fig. 1, are provided; in this case the fixed supports may not coincide with the gas inlet branch 14. In a further arrangement, Fig. 8, the inlet scroll 36 extends over an arc of approximately 180 degrees, but the gas inlet branch 35 is disposed at one end thereof; the fixed support is indicated at 37 and the movable supports at 38.
