Double U design for mid-turbine frame struts
First Claim
1. A mid-turbine frame connected to at least one mount of a gas turbine engine for transferring a first load from a first bearing and a second load from a second bearing to the mount, the mid-turbine frame comprising:
- a first load structure for combining the first load and the second load into a combined load;
a second load structure for transferring the combined load to the mount;
a plurality of struts connected between the first load structure and the second load structure for transferring the combined load from the first load structure to the second load structure.

Abstract
A mid-turbine frame is connected to at least one mount of a gas turbine engine for transferring a first load from a first bearing and a second load from a second bearing to the mount. The mid-turbine frame includes a first load structure, a second load structure, and a plurality of struts. The first load structure combines the first load and the second load into a combined load. The second load structure transfers the combined load to the mount. The struts are connected between the first load structure and the second load structure and transfers the combined load from the first load structure to the second load structure.
