Title:
ROTOR AIRFOILS TO CONTROL TIP LEAKAGE FLOWS
Document Type and Number:
WIPO Patent Application WO1996014494
Kind Code:
A3
Abstract:
A rotor blade for a gas turbine engine includes a bowed surface on a tip region of the suction side thereof. The curvature of the bowed surface progressively increases toward the tip of the blade. The bowed surface results in a reduction of tip leakage through a tip clearance from the pressure side to the suction side of the blade and reduces mixing loss due to tip leakage.
