Gas turbine with knivtætning between the rotor blades and the housing vanes.

摘要

An arrangement is set forth for mounting knife edge seals on a rotating bladed disk for sealing cooperation with sealing lands on a ring, fixed against rotation, connected to the inner ends of adjacent vanes. The knife edge seals are fixed to a sealing member which is removably positioned on a cylindrical-like flange on the disk. Radially mounted headed pins, held in position by centrifugal force during engine operation, fix the sealing member to the disk flange, while a pin retaining ring holds the pins in place when the disk is at rest.
