Abstract

1,195,027. Gas turbine jet propulsion plant; axial flow fans. BRITISH AIRCRAFT CORP. Ltd. Feb. 5, 1968 [Nov. 8, 1966], No. 50031/66. Headings F1C and F1J. A gas turbine ducted fan aircraft engine has a fan cowl 23 formed by inlet and exhaust sections 25, 26, respectively, both fabricated from radially spaced skins of light-gauge sheet material and joined to each other by an intermediate section 27 consisting of a single skin surrounding the periphery of the fan 18 and of sufficient thickness to contain accidentally detached fan parts. The outer and inner skins 40, 42, Fig. 3, of the inlet section 25 are braced by longitudinally extending ribs 44 having holes 48 to receive securing bolts for lugs 46 of the intermediate section 27. Similar ribs 45 brace the skins 41, 43 of the outlet section 26 and have holes 49 to receive securing bolts for further lugs 47 of section 27. Straps 50, 51 cover the access openings to the bolts. The single skin of section 27 may be formed of a single thickness of material or of a sandwich of two or more materials in surface contact. As shown in Fig. 1 the cowl 23 is applied to a three-spool type aft fan engine and is supported from the engine by radial struts 24, 28. Compared with a conventional fan cowl, shown dotted at 30, the cowl 23 is shorter and has a smaller external diameter, thus reducing drag. The cowl may also be applied to a front fan engine, Fig. 2 (not shown).
