Abstract

An aircraft is provided with fixed wings 2 and external bracings 4 therefor, the latter serving as auxiliary lifting surfaces, the aspect ratio of the whole lifting surfaces being not less than fifteen, while the wing loading is not less than 80 kg./sq. meter. Figs. 8 and 9 show a section through a wing 2 and strut 1 near their junction, figs. 10, 11 and 12 showing the increasing angle of incidence of the strut throughout its length inboard towards the fuselage. A form of wing shown in nos. 13 and 14 comprises upper and lower skins 104,‘ 105 secured at their leading edges by a member 110 and at their rear edges by angle sections 111, 112. Separate ribs 108, 109 are provided for the respective sections, appropriately shaped openings being formed for the stringers 106, 107. Figs. 15 and 16 show an arrangement of flaps 113 and ailerons 114, the latter being operable as lift flaps in addition to fulfilling their normal function. The flaps arc operated by a handle 122 connected by chain‐and‐sprocket to a screwed shaft 120 carrying sleeves 119 connected to the ends of levers 117, whose other ends'are connected to links 116 operating the flaps. The levers 117 arc connected to further levers 127 operating links 126 connected to the ailerons, so that simultaneous movement of the latter also results from operation of the handle 122. Differential movement of the ailerons is obtained by movement of a link 134 connected to one end of a lever 131 whose other end is pivoted to the mid‐point of a further link 130 connecting the levers 127.
