Abstract

1,191,941. Variable-sweep wings. BRITISH AIRCRAFT CORP. Ltd. 6 May, 1968 [3 March, 1967], No. 10240/67. Headings B7G and B7W. A variable sweep wing has its root chordwise-section so profiled that it retains substantially the same shape and dimensions irrespective of the sweep angle, thereby reducing to a minimum the extent of the sealing that is necessary in the opening provided in the fuselage to receive the wing. The wing 12 is mounted on a pivot 20 adjacent the wall 21 of the fuselage which is formed with a cut-out 14 to accommodate the root portion of the wing and is formed with slideways 25, 26 to support sealing plates 15, 16. The root portion of the wing is so profiled that contour lines a to h, a<SP>1</SP> and a<SP>11</SP> are arranged to be of constant height from a given datum e.g. a plane containing the leading and trailing edges and the mid-parts 24 of the wing within contour h are substantially flat. In consequence when the wing is moved from the position shown in Fig. 2 to a position of greater sweep the section of the wing in the plane of the opening 14 in the fuselage wall so far as the leading and trailing edge parts 22 and 23 are concerned whilst the flat portions 24 extend fore and aft of the pivot 20. The sealing plates 15, 16 may be flat or contoured plates or they may be segmented or flexible, and they may be interconnected one with another and with the wing-actuating mechanism for movement with the wing during changes in sweep angle. Provision may be made to enable the plates to move vertically to allow for wing movements in flight and under static loads.
