TIP LEAKAGE FLOW DIRECTIONALITY CONTROL |
摘要 |
An airfoil according to an exemplary aspect of the present disclosure includes, among other things, a suction sidewall and a pressure sidewall, each sidewall extending spanwise from an airfoil base and extending chordwise between a leading edge and a trailing edge. A tip wall extends chordwise from the leading edge to the trailing edge and joining respective outer spanwise ends of the suction and pressure sidewalls. A tip leakage control channel is recessed into the tip wall, the tip leakage control channel including a control channel floor that extends between a first control channel vane sidewall and a second control channel vane sidewall established by a corresponding tip leakage control vane. An internal cooling cavity is disposed between the suction sidewall and the pressure sidewall and a channel cooling aperture feeds airflow from the internal cooling cavity to the tip leakage control channel. |

1. An airfoil, comprising:
a suction sidewall and a pressure sidewall, each sidewall extending spanwise from an airfoil base and extending chordwise between a leading edge and a trailing edge; a tip wall extending chordwise from said leading edge to said trailing edge and joining respective outer spanwise ends of said suction and pressure sidewalls; a tip leakage control channel recessed into said tip wall, said tip leakage control channel including a control channel floor that extends between a first control channel vane sidewall and a second control channel vane sidewall established by a corresponding tip leakage control vane; an internal cooling cavity disposed between said suction sidewall and said pressure sidewall; and a channel cooling aperture that feeds airflow from said internal cooling cavity to said tip leakage control channel. |
