Collar support assemblies are provided. For example, a collar support assembly for an airfoil comprises a collar that includes a first surface shaped complementary to a fillet of the airfoil and a planar second surface. The first surface is disposed adjacent the fillet of the airfoil. The collar support assembly further comprises a shim material disposed between the second surface and an airfoil support structure and a filler material inserted between the first surface and the fillet of the airfoil to provide a tight fit between the collar and the airfoil. In other embodiments, the collar support assembly comprises a pair of collars and supports an airfoil doublet. The airfoil doublets may be part of an outlet guide vane assembly of a gas turbine engine, and methods for assembling outlet guide vane assemblies also are provided.

A doubler attachment system is provided for fixedly coupling a strut to an engine casing. The strut includes at least one flanged end configured to mate with the engine casing. The doubler attachment system includes a doubler plate having a first radial surface and a second opposing radial surface. The first radial surface is configured to mate with and conform to a contour of the at least one flanged end of the strut. The doubler attachment system further includes at least two bolts fixedly attached to the doubler plate at the first radial surface. The at least two bolts extend radially away from the first radial surface and toward the engine casing.

Doubler attachment system

A strut assembly for a gas turbine engine includes an outer structural case. The outer structural case includes a first mounting pad for mounting a first strut and a second mounting pad for mounting a second strut. The outer structural case further includes a case ligament extending between the first mounting pad and the second mounting pad in a substantially straight direction to reduce an amount of bending stress on the outer structural case.
