Abstract

A method of manufacture of a cladding body (34) for an edge of an aerofoil (32), the method including the step of providing a core member shaped to include an elongate recess (60) portion for mounting on the edge of the aerofoil, the elongate recess portion being shaped across its width to define a smoothly curved concave surface. A support member (54) is provided; the support member has a support portion (62) for complementary engagement with the recess portion. Both the support member and the core member are arranged between a pair of opposing membranes. The core member is bonded to each of the pair of membranes to form an intermediate cladding body, wherein the recess portion of the core member is arranged to engage, at least during the bonding step, the support portion to be supported thereby. At least the membranes are shaped using a hot forming process.
