Abstract: 1,161,305. Aerofoil construction. PARSONS CORP. 13 March, 1968. No. 12213/68. Heading B7W. A hollow fixture 10, for use in bonding structural members (e.g. metal elements a ... d, e, f, g, g 1 , g 11 , h) to form an aerofoil (e.g. a helicopter blade), has upper and lower portions 12, 14 hollowed from a parting plane i-i so as to define a cavity 20 wherein the structural members a-h may be received, including aft converging portions of the upper and lower inner surfaces, one 12 of the surfaces having a recess 24, in which fluid pressure applying means (e.g. an inflatable tube 30 and a rail 26) fill the recess, apply inward pressure at the converging surface (e.g. at 28) reacted by a fixture portion 34 on the opposite portion 14 of the fixture, the inward pressure and reaction are capable of applying a forward component of force reacted by a rearward pressure reacting member 38 (which may have an inflatable bag 40) forward of the recess 24. The fixture may also include a recess 24 1 at the trailing edge having a rail 26 1 and an inflatable bag 30 1 to apply a forward pressure to assist with members 18, 18 1 , 18 11 in holding the metal elements a ... h while the areas s are heated and pressed together.
