Structural stator airfoil |
摘要 |
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. |

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; an outer platform coupled to a tip section of the airfoil, the outer platform comprising a multi-lobed gusset extending along an upper surface of the outer platform, opposite the tip section; wherein the multi-lobed gusset comprises four legs meeting at a nexus, wherein two of the four legs extend axially forward from the nexus and two of the four legs extend axially aft from the nexus. |
