Abstract: An energizing element including: an energizing element body oriented about a central axis, the energizing element body defining an inner radius, IR, and an outer radius, OR, where the difference between the outer radius and the inner radius defines an adjusted width, W, of the energizing element body, where the inner radius and the outer radius determine an average radius, R, of the energizing element body about the central axis, where the energizing element body defines an aspect ratio, W/R, where W/R>0.1, where the energizing element body has a maximum linear contact length on the inner radius, LIR, where the energizing element body has a perimeter on the inner radius, PIR, and LIR/PIR>0.80, where the energizing element body has a maximum linear contact length on the outer radius, LOR, where the energizing element body has a perimeter on the outer radius, POR, and LOR/POR>0.55, and where the adjusted width is less than 5 mm.

Abstract: A method of forming a three-dimensional body from a mixture, wherein the mixture can comprise dispersed solid polymeric particles and a curable binder. In a particular embodiment the solid polymeric particles can be fluoropolymeric particles. The method can include at least partial removal of the cured binder and sintering, to obtain a sintered polymeric three-dimensional body. In one embodiment, the sintered three-dimensional body can be PTFE.

Abstract: Systems and methods include providing a stator vane bushing for a variable stator vane assembly having a movable stator vane and a stator vane housing disposed annularly about the movable stator vane. The bushing includes a flange, a barrel extending from the flange, and a central aperture extending through the flange and the barrel and is disposed in the housing and annularly about the stator vane. The bushing is formed from a ceramic material having a coefficient of thermal expansion (CTE) lower than or equal to a CTE of one or more of a stator vane and a housing of the variable stator vane assembly.
