Abstract
A method and tooling for assembling a guide vane stage that includes an inner shroud and an outer shroud that are coaxial and interconnected by radial airfoils, the method including holding plates pressed against an outer surface of the inner shroud so that the plates cover gaps formed between openings in the inner shroud and the airfoils at least in part and in a manner that is leaktight, and applying a sealing resin to the inner surface of the inner shroud so that the resin fills the gaps and so that radially inner ends of the airfoils are embedded in the resin.
