Abstract:
A vane construction for a gas turbine comprising an assembly of vane elements, each vane element including a vane blade and outer and inner platforms at upper and lower ends of said vane blade, said outer and inner platforms being integrally formed with said vane blade, said outer platform having means for attachment to a housing, at least one of said platforms having a first surface with a projection extending laterally from said first surface, said projection having upper and lower surfaces extending perpendicularly from said first surface, said at least one platform further having a second surface with a recess disposed opposite said projection and of a shape corresponding to that of said projection such that in the assembly of vane elements, said projection of one vane element form-fits into the recess of an adjacent vane element and the platforms of the adjacent vane elements are flush with one another, so as to be restrained thereby to prevent relative radial movement of said vane elements.
