Classification: CPC F | IPC F

Claim 16:
17. A component for a turbine engine, comprising:
a body with an exterior surface having a leading edge and a trailing edge and abutting a combustion flowpath for a combustion gas flow through the turbine engine;
a trench on the exterior surface having a curved wall and defining a trench outlet, the curved wall defining a projecting tip with the exterior surface and extending at least partially extends over the trench with a proximal end of the projecting tip closer to the leading edge of the component and a distal tip end of the projecting tip closer to the trailing edge of the component;
a cooling passage defined within the body and supplying cooling air to the component; and
at least one outlet on the trench fluidly coupled to the cooling passage and defining a cooling axis, with the cooling axis extending at least partially downstream with respect to the combustion flowpath;
wherein the curved wall comprises a first portion tangent to the at least one outlet and a second portion tangent to the exterior surface at the trench outlet for directing the cooling air from the trench downstream onto the exterior surface.
