First Claim
Patent Images
1. A vane for use in a gas turbine engine comprising:
- an airfoil extending between a leading edge and a trailing edge, and being generally hollow;
a radially outer platform and a radially inner platform; and
with at least one of said radially inner and radially outer platforms having thicker portions circumferentially located beyond one of said leading edge and said trailing edge, and thinner portions circumferentially beyond circumferential edges of said airfoil.

Abstract
A vane for use in a gas turbine engine has an airfoil extending between a leading edge and a trailing edge, and is generally hollow. The vane has a radially outer platform and a radially inner platform. At least one of the radially inner and radially outer platforms has thicker portions circumferentially located beyond one of the leading edge and the trailing edge, and thinner portions circumferentially beyond circumferential edges of the airfoil. A mid-turbine frame and a gas turbine engine are also disclosed.
