Title: Leaktight seal of a circular vane stage

Abstract: A leaktight seal includes plaquettes that are housed between platforms of ""hammer legged"" vanes and a periphery of a rotor disc. The plaquettes lie above a throat that receives legs between a collar. The plaquettes are completed with heels that also lie between the legs. Centrifugal forces distort the seal and produce excellent leaktightness between the disc and the platforms.
