Torna indietro

Abstract

A method of manufacturing a wing structure (10) is described. A plurality of layers of preimpregnated material are laid on a first mould half (51) and on a second mould half (52) so as to form a first fresh skin (22) and a second fresh skin (21) of the wing structure. A plurality of layers of preimpregnated material are laid in succession on a shaped apparatus (80) so as to form a fresh leading edge skin (23) of the wing structure. Fresh spars (30) of preimpregnated material are formed. A wedgelike body (40) of expanded plastics material is formed, this body being designed to be interposed between the first and second skins at the trailing edge of the wing structure. The fresh spars are positioned in a coordinated way on the first fresh skin, removable support members (100) also being positioned next to the spars. The second mould half is turned over on to the first mould half so as to position the second fresh skin on the spars and the support means, so as to produce a fresh wing structure. The fresh wing structure is subjected to a polymerization cycle, using a vacuum bag
