Turbine engine variable stator vane

摘要

A turbine engine variable stator vane (26) includes a platform (32) having a circumference adjoining opposing surfaces. A trunnion (30) extends from one of the opposing surfaces. An airfoil (29) is supported on the other of the opposing surfaces opposite the trunnion. The airfoil includes leading and trailing edges (40, 42). An overhanging portion of the airfoil (29), which includes the trailing edge (42), extends beyond the circumference. A fillet (50) joins the airfoil (29) and the other opposing surface and extends along the other opposing surface in a lateral direction beyond the circumference toward the trailing edge (42). In one example, the fillet (50) is provided about the entire perimeter of the airfoil. The airfoil includes pressure and suction sides (36, 38). The circumference includes a relief cut (52) extending from the suction side (38) and adjoining a notch (54) in the circumference to form an apex (53) overlying the end surface (48) of the overhanging portion.
