Abstract: A vane support system includes a frame and a vane. The frame has a first end configured to engage to a first platform and a second end configured to engage a second platform, so the frame can structurally support at least one of the first platform and the second platform. The first and second ends define a vane axis therebetween. The vane is mounted to the frame about the vane axis. A gas turbine engine includes a case defining a centerline axis of the engine, an inner housing and a plurality of variable vanes. The inner housing is radially inward of the case with respect to the centerline axis. At least one of the variable vanes structurally supports the case and the inner housing in response to at least one of radial, axial or tangential loads with respect to the centerline axis.
