Abstract (en)
A rotor blade includes an airfoil 106 having a blade tip 120 and a tip cavity 134 formed at the blade tip. The blade tip defines a radially outer surface of the airfoil. The tip cavity includes a tip cap 136 that is recessed radially inwardly from the tip and surrounded by pressure 114 and suction 116 side walls of the airfoil. The tip cap is in fluid communication with an internal cavity defined within the airfoil. A portion of the suction and/or the pressure side wall that define the tip cavity extends obliquely outwardly from the tip cavity. A plurality of slots 148 is defined in the suction and/or the pressure side wall along the radially outer surface proximate to the trailing edge of the airfoil.
