摘要： A turbine section of a turbine engine includes rotatable structure, an outer casing disposed about the rotatable structure, and an inner casing disposed about the rotatable structure and suspended radially inwardly from the outer casing. Rotation of the rotatable structure during operation drives at least one of a compressor and a generator. The inner casing defines a hot gas flow path through which hot combustion gases pass during operation. The inner casing comprises a plurality of wall sections. Each wall section includes a panel having an inner portion and an outer portion opposed from and affixed to the inner portion. The inner portion at least partially defines the hot gas flow path and the inner portion is radially spaced from the outer portion such that a substantially fluid tight chamber is formed therebetween. The fluid tight chamber reduces thermal energy transfer from the inner portion to the outer portion.

摘要： A wear prevention system for securing compressor airfoils within a turbine engine while reducing wear of related components may include a compressor diaphragm spring positioned in an airfoil receiving channel between a radially outer surface of a diaphragm base and a radially inner surface of the airfoil receiving channel. The spring may bias the diaphragm base and airfoil attached thereto radially inward against upstream and downstream arms formed from upstream and downstream recesses extending axially from the airfoil receiving channel in the compressor case. The compressor diaphragm spring may dampen vibration and increase service life of the diaphragm base.

摘要： An annular combustor for a jet turbine engine of generally rectangular cr-section having an axially-projecting aft exhaust outlet is lined by a plurality of circumferentially-extending heat-insulating liner segments, preferably ceramic, spaced from the metal shell of the combustor by spring-like spacers. The liner segments have offset tabs at their edges to slidably mate with each other and with retaining clips adjacent to the exhaust outlet, thereby being slidably secured to accept expansion of the metal shell without placing appreciable stress on the liner segments. Arcuate, generally planer liner segments along the forward and aft walls of the combustor are keyed in place by a radially-inward flanged liner segment along the outer perimetrical wall of the shell.
