Abstract (en)

[origin: EP1881157A1] A turbine engine component (90), such as a turbine blade, has an airfoil portion (104) with a pressure side and a suction side. The turbine engine component (90) also has a first cooling circuit (100) within the pressure side for cooling the pressure side of the airfoil portion (110) and a second cooling circuit (120) within the suction side for cooling the suction side of the airfoil portion (104) and for cooperating with a wrap around leading edge cooling circuit (126) for creating a cooling film over the pressure side.
