Gas turbine engine component with impingement and diffusive cooling
Abstract:
A gas turbine engine component includes a gas path wall having a first surface and second surface and an impingement baffle having impingement holes for directing cooling fluid onto the first surface of the gas path wall. A cooling hole extends through the gas path wall. The cooling hole continuously diverges from an inlet in the first surface to an outlet in the second surface such that cross-sectional area of the cooling hole increases continuously from the inlet to the outlet. A longitudinal ridge divides the cooling hole into lobes.
