Abstract

The structure (11) preferably comprises a hollow leading edge aerofoil, in which the ribs (15) define passages (17, 18) for fluid circulation in use. The composite is wrapped around hollow mould tool parts (25, 31) which are nested together between inner and outer composite skins (13, 12) within external mould tool parts (33, 34), and moulded under heat, and pressure which may partly be applied by internal pressurisation of the hollow mould tool parts, which may be of aluminium and may be removed from the cooled structure by etching. The composite is preferably fibre reinforced thermoplastic. The ends of the hollow mould tool parts (25, 31) may be rectangular, to provide aerofoil end regions for support and attachment of trailing edge skins, and attachment of fluid circulation supply means. <IMAGE>
