A high pressure turbine (HPT) blade includes a substantially arcuate trailing edge including one or more fluid injection elements disposed therein. Each fluid injection element injects a fluid such as air into a desired trailing edge region of the HPT blade or vane to enhance mixing out of the wakes generated via the HPT blade or vane. The enhanced mixing out reduces HPT/LPT interaction losses and/or the axial gap between the HPT and LPT components in a gas turbine engine. The interaction losses include unsteady thermal wake segregation effects that lead...
1. A high pressure turbine (HPT) blade or vane comprising: a crenulated trailing edge comprising one or more chevrons disposed on the pressure side, suction side, or both the pressure side and suction side of the HPT blade or vane and configured to enhance mixing out of wakes generated via the HPT blade or vane, such that aerodynamic losses due to corresponding wake and shock interactions are reduced to a desired level, and further such that corresponding thermal wake segregation effects are reduced to a desired level. 2. The HPT blade or vane according ...
