Abstract:
1. A mid-turbine frame assembly 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 assembly comprising: a plurality of inverted panels positioned perpendicular to an axis of the gas turbine engine and that convert the first and second loads to a one-directional shear flow, wherein each inverted panel comprises: a plurality of radial stiffeners that direct the loads in a radial direction within the inverted panel; and a plurality of circumferential stiffeners that direct the loads in a circumferential direction within the inverted panel, wherein the plurality of radial stiffeners and the plurality of circumferential stiffeners form a plurality of torque cells and wherein the first and second loads are converted to the one-directional shear flow at the plurality of torque cells, wherein the plurality of torque cells have at least a three-by-three configuration; a first bearing cone connected between the first bearing and the inverted panels, wherein the first load is transferred to the inverted panels through the first bearing cone; a second bearing cone connected between the second bearing and the inverted panels, wherein the second load is transferred to the inverted panels through the second bearing cone; and a plurality of struts connected to the inverted panels that transfer the one-directional shear flow to the mount.
