PROBLEM TO BE SOLVED: To provide an airfoil (82) for rotor blades (80). SOLUTION: The airfoil (82) comprises: a pressure sidewall (90); a suction sidewall (92) connected with the pressure sidewall at a leading edge (86) and a trailing edge (88); a plurality of first trailing edge slots (150) extending along the pressure sidewall from the trailing edge; and at least one second trailing edge slot (152). Each of the plurality of first trailing edge slots (150) and at least one of the second trailing edge slots (152) has an inlet port (162), an outlet port (168), and a length fixed between them, respectively. At least the one second trailing edge slot has a length longer than those of the plurality of first trailing edge slots. COPYRIGHT: (C)2007,JPO&INPIT |
