ROTOR BLADE HAVING FLARED TIP

摘要

PROBLEM TO BE SOLVED: To provide a blade tip design having improved blade tip trailing edge cooling.SOLUTION: A rotor blade includes an airfoil having a blade tip and a tip cavity formed at the blade tip. The blade tip defines a radially outer surface of the airfoil. The tip cavity includes a tip cap that is recessed radially inwardly from the tip and surrounded by pressure and suction side walls of the airfoil. The tip cap is in fluid communication with an internal cavity defined within the airfoil. A portion of at least one of the suction side wall and the pressure side wall defining the tip cavity extends obliquely outwardly from the tip cavity. A plurality of slots are defined in at least one of the suction side wall and the pressure side wall along the radially outer surface proximate to the trailing edge of the airfoil.SELECTED DRAWING: Figure 1
