VANE STRUCTURE AND A METHOD OF MANUFACTURING A VANE STRUCTURE

摘要

A fuel injector comprises a swirler and the swirler comprises a plurality of vanes, a first member and a second member. The second member is arranged coaxially around the first member and the vanes extend radially between the first and second members. The vanes have leading edges and the second member has an upstream end. The leading edges of the vanes extend with radial and axial components from the first member to the upstream end of the second member and the radially outer ends of the leading edges of the vanes form arches with the upstream end of the second member. The arrangement of the swirler enables the fuel injector to be built by direct laser deposition.
