Abstract
A system and method for generating a smooth blending fillet surface between a platform and an airfoil shape mounted thereto. This is accomplished by generating a fillet surface by acquiring descriptions of an airfoil shape (e.g., the pressure side, the leading edge, the suction side and the trailing edge), a platform surface, a platform footprint, and filleting curves for the pressure and suction sides of the airfoil. These descriptions are used produce a smooth mesh of points which capture both the blending fillet surface and the airfoil. The smooth mesh of points are used to render slope-continuous blended fillet surfaces.
