ABSTRACT:
Passive clearance control is attained for rotor blades for gas turbine engines in environments where the airfoil of the rotor is solid or where coolant is unavailable or is available but not at sufficient quantity to provide passive clearance control. In this situation a judiciously located curved slot extending from the tip of the blade adjacent the pressure side and terminating at the pressure side at a location where there is sufficient static pressure so that the pressure drop across the slot induces a pumping action. In embodiments where there is sufficient coolant for tip cooling, the curved slot is judiciously located to be in communication with the film cooling hole discharging on the pressure side of the blade and the tip of the blade adjacent the pressure side of the blade.
