Abstract:
A sealing system for a rotatable element defining an axis of rotation includes a rotor blade including a shank and an angel wing extending axially from the shank. The sealing system also includes a stator vane positioned axially adjacent the rotor blade. The stator vane includes a platform extending in an axial direction over the angel wing such that a clearance gap is defined therebetween. The sealing system also includes a sealing mechanism including a portion of the platform and a portion of the angel wing. The sealing mechanism includes at least one obliquely oriented surface such that the clearance gap defines a converging nozzle.
