Abstract
Official abstract text for this publication.
An airfoil comprises a leading edge, a trailing edge, and pressure and suction surfaces defined therebetween. An inner platform is coupled to a root section of the airfoil, with a curvilinear gusset extending along a lower surface of the inner platform, opposite the root section. An outer platform is coupled to a tip section of the airfoil, with a multi-lobed gusset extending along an upper surface of the inner platform, opposite the tip section.
First claim
Opening claim text (preview).
The invention claimed is: 1. An airfoil comprising: a leading edge, a trailing edge, and pressure and suction surfaces defined therebetween; an inner platform coupled to a root section of the airfoil, the inner platform comprising a curvilinear gusset extending along a lower surface of the inner platform, opposite the root section, wherein the curvilinear gusset extends along a camber line of the airfoil defined in the root section of the airfoil opposite the curvilinear gusset;…
