Microcircuit cooling for turbine vanes |
摘要 |
<p>A turbine engine component (12) has an airfoil portion (10) with a suction side (14). The component (12) includes a cooling microcircuit (32) embedded within a wall structure forming the suction side (14). The cooling microcircuit (32) has at least one cooling film hole (36) positioned ahead of a gage point (38) for creating a flow of cooling fluid over an exterior surface of the suction side (14) which travels past the gage point (38). The cooling microcircuit is formed using refractory metal core technology. A method for forming the cooling microcircuit is described.</p> |
