Abstract

938,286. Gas turbine engines; jet propulsion plant. ROLLS-ROYCE Ltd. April 27, 1962 [May 4, 1961], No. 16286/61. Class 110 (3). A gas turbine engine has at one end thereof a central fairing or bullet member which is supported from the outer casing or wall by one or more struts which extend across the annular passage formed between the central fairing and the outer wall, the fairing and the struts being formed in two or more pieces which are detachable from each other so that when at least one piece is removed, access is given to the interior of the fairing and each strut. In the gas turbine engine shown in Fig. 1 a fairing 17 is disposed centrally within the compressor intake, the fairing being supported from the compressor wall 18 by a pair of hollow struts 19. The fairing is hollow and a starter motor 20 and a fuel control unit 21 are supported therein, the connections to the two units passing through the hollow struts. The fairing is divided at 23 into a forward portion 17a and a rearward portion 17b and each strut is also divided at 32 into a forward portion 19a and a rearward portion 19b, the forward portions of the fairing and struts being formed as a unit, and likewise the rearward portions. The joints between the parts are sealed as shown in Fig. 5, a sealing strip 25 secured to the inner surface of the forward portion 19a extending beyond the joint 23 and being received between a sealing member 26 secured to the inner surface of the rearward portion 19b. The forward unit may be removed by unscrewing the nuts 31 and by releasing bolts securing the outer ends of the struts to the compressor casing thus giving access to the units 20, 21 mounted within the hollow fairing. The central fairing and struts also the outer casing may be formed from glass or asbestos fibres impregnated with resin.
