Abstract
A vane element adapted for assembly with a plurality of further vane elements to form a ring of vanes for a low pressure gas turbine. Each vane element has a vane blade with platforms at its outer and inner ends, the platform at the outer end being adapted for connection to a housing. Each platform has a flange integral with the vane blade and an outer wall spaced radially from the flange and joined thereto by a radial wall having a lateral projection. Opposite the projection, a recess is formed between the flange and the outer wall, the recess having a shape corresponding to that of the projection so that a plurality of the vane elements can be assembled to form the vane ring by engaging the projection of one vane element in the recess of an adjacent vane element. The projections are form-fit in the recesses so that the platforms of the vane elements are flush with one another.
