Abstract
A turbine airfoil having a cut-back trailing edge and a plurality of diffusing flow dividers upstream of the cut-back trailing edge is disclosed. Various construction details are developed which provide ejection of a diffusing film of cooling fluid over a cut-back trailing edge. In one particular embodiment, a turbine airfoil includes a plurality of radially spaced flow dividers extending between a pressure wall and a suction wall. Each flow divider includes a rounded leading edge, a pair of parallel sidewalls downstream of the leading edge, and a pair of converging sidewalls downstream of the parallel sidewalls. Adjacent sidewalls of adjacent flow dividers form flow channels having a constant area channel and a diffusing section. The diffusing section includes a covered portion upstream of the cut-back trailing edge and an uncovered portion extending over the cut-back trailing edge.
