The fillet is externally shaped so as to have an arc-shaped curved surface having a radius of R as viewed in a cross-section orthogonal to the flow path wall surface and the blade surface of the blade profile section. A narrow portion existing on the flow path wall surface is configured such that the distance d between the outer edge of a projection of the blade profile section onto the flow path wall surface and the outer edge of the flow path wall surface is smaller than the maximum value of the radius R of the fillet. The upper end of the fillet is positioned lower in the narrow portion than that in a region other than the narrow portion, and the lower end of the arc-shaped curved surface coincides with the flow path wall surface along the entire circumference of the blade profile section. | 2020-06-11 |
20200182062 | MULTI-MATERIAL LEADING EDGE PROTECTOR - An airfoil that includes an airfoil body having a root and a tip, and convex and concave sides that extend between a leading edge and a trailing edge. The airfoil also includes at least a first cladding element that is attached to the airfoil body. The first cladding element includes a first portion and a second portion. The second portion is configured to separate from the first portion when the first cladding element encounters a force of at least a predetermined amount. | 2020-06-11 |
