摘要： A hot gas seal for sealing an opening in a heat shield element or between heat shield elements of a heat shield includes a resilient portion for providing a force which is designed such that the hot gas seal can be held in the opening by the force and/or that the sealing efficiency of the hot gas seal is increased by the force. Further, a hot gas seal assembly for sealing an opening in a heat shield element or between heat shield elements of a heat shield against a hot gas is provided, the assembly including a sealing body and a further sealing element which is in a solid state at room temperature and in a high viscosity liquid state at a temperature of the hot gas.

摘要： An inventive hot gas seal for sealing an opening, e.g. a gap or hole, in a heat shield element or between heat shield elements of a heat shield or a liner comprises at least one resilient portion for providing a force which is designed such that the hot gas seal can be held in said opening by said force and/or that the sealing efficiency of the hot gas seal is increased by said force. Thus, further means for holding the seal in place and/or for increasing the sealing efficiency are not necessary. The invention is particularly useful if the design of said resilient portion is such that the force provides a holding action and increases the sealing efficiency, at the same time.

摘要： A combustor (40) for a gas turbine engine is provided with a premix pilot fuel stage (42) in order to reduce the emission of oxides of nitrogen from the engine. An in-service engine may be modified to add the premix pilot fuel stage by delivering premix pilot fuel to a ring manifold (42) for tip-feeding a premix pilot fuel outlet member such as a swirler vane (78) or fuel peg (124). In this manner, complex and expensive components such as the top hat (46), support housing (48) and diffusion pilot burner assembly (44) may be used without modification. Thermal stresses caused by the differential cooling of the ring manifold by the premix pilot fuel (96) are reduced by a heat shield (94) installed within the manifold.

摘要： A heat shield manifold system for an inner casing between a compressor and turbine assembly is disclosed. The heat shield manifold system protects the outer case from high temperature compressor discharge air, thereby enabling the outer case extending between a compressor and a turbine assembly to be formed from less expensive materials than otherwise would be required. In addition, the heat shield manifold system may be configured such that compressor bleed air is passed from the compressor into the heat shield manifold system without passing through a conventional flange to flange joint that is susceptible to leakage.

摘要： A split ring wedge bearing friction damper for an aero engine that allows the engine to operate without an oil tank, a pump, and a lubricant cooler, the friction damper having a damper ring and a wedge ring that both have wedge surfaces in contact so that an axial load can be applied to the bearing outer race to provide damping to the bearing, and so that the damper ring can also have a radial displacement to produce a radial load on the damper ring against the stator bearing support surface in which the axial load provides the friction damping and the radial load eliminates lost motion for maximum damping.
