<p>A cooling circuit 26 is disposed within a wall particularly within a gas turbine engine. The cooling circuit 26 includes a forward end 30, an aft end 40 and first, second and third sets of pedestals 42, 43, 45 which extend between first and second portions 34, 36 of the wall. At least one inlet aperture 56 provides a cooling airflow path into the forward portion of the cooling circuit from a cavity 58. A plurality of exit apertures 60 formed between the second and third pedestals 43, 45 provide a cooling airflow path out of the aft portion 40 of the cooling circuit and into the core gas path outside the wall. The second pedestals 43 are T-shaped in section</p> |
