Abstract:
1. An assembly for a turbomachine comprising: a plurality of components which, in use, are assembled into a circumferentially extending annular array; each component includes a radially outer platform, a radially inner platform and an aerofoil which is twisted along its length extending therebetween, the radially outer platforms of the components forming a ring in the assembled circumferentially extending annular array, wherein: adjacent components interface at adjacent surfaces of their outer platforms, and the adjacent surfaces are angled away from the radial direction; the radially outer platforms each include at least one lug which extends from an outer surface of the radially outer platform over a portion of the radially outer platform of an adjacent component, and in use, substantially prevents relative radial displacement of the radially outer platform of the adjacent component; and the radially outer platforms are disposed at a greater radial distance than the radially inner platforms.
