Abstract (en)
A turbine engine component (90) has an airfoil portion (110) with a pressure side (116) and a suction side (118). The turbine engine component (90) further has a first cooling microcircuit (102) for cooling the suction side (118) of the airfoil portion (110). The first cooling microcircuit (102) is embedded within a first wall (106) forming the suction side (118). The first cooling microcircuit (102) has a circuit for allowing a cooling fluid in the first cooling microcircuit (102) to exit at a tip (134) of the airfoil portion (110). The turbine engine component also has a second cooling microcircuit (100) embedded within a second wall (104) forming the pressure side (116) of the airfoil portion (110).
