Abstract

1,040,948. Aircraft wings. DOW CHEMICAL CO. July 23, 1963 [July 26, 1962], No. 29072/63. Heading B7W. An aerofoil structure comprises a core having section 12 of rigid foam, such as polyurethane, polystyrene or aluminium, bonded together, a multiplicity of tubular spars 14 running spanwise through the core, the spars being spaced apart, and disposed adjacent to the periphery of the core, and a skin 28, e.g. of epoxy resin bonded glass fibre, bonded to the core. As described, the spars pass through preformed holes in the sections and are bonded to the core by epoxy resin, as are the sections of the core to each other and the skin to the core. Aluminium plates 16 and 66 are bonded to the core at each end, and a wing-tip 20 comprising rigid foam covered with glass fibre is bonded to the plate 66. At the inboard end, threaded inserts 62 are fixed to the spars 14 for attachment to a wing mounting. Flaps 54 and ailerons (Fig. 3, not shown) of similar construction are hinged to the trailing edge, and the core may be hollowed or bored to receive, e.g. fuel tanks and control rods.
