Low loss airfoil platform trailing edge |
摘要 |
An airfoil platform comprises a leading edge portion and a trailing edge portion. The trailing edge portion comprises a first region having a convex flowpath contour, a second region having an intermediate flowpath contour extending downstream from the convex flowpath contour, and a third region having a concave or linear flowpath contour extending downstream from the intermediate flowpath contour to a downstream end of the trailing edge portion of the platform. |

1. An airfoil with a platform, the platform comprising:
a leading edge portion; and a trailing edge portion aft of a trailing edge of the airfoil, the trailing edge portion comprising:
a first region having a convex flowpath contour that begins aft of the trailing edge of the airfoil;a second region having an intermediate flowpath contour extending downstream from the convex flowpath contour; anda third region having a concave or linear flowpath contour extending downstream from the intermediate flowpath contour to a downstream end of the trailing edge portion. |
