    摘要： A fuel injector for injecting fuel in a burner of a gas turbine where the fuel injector has a body with an inner hole and a valve element which is slideably arranged inside the inner hole. The body has a fuel inlet which is formed into the body for injecting fuel into the inner hole, wherein the fuel inlet is coupleable to a fuel supply line. The body further has a first outlet channel connected to the inner hole, wherein the first outlet channel is further coupleable to a burner. The valve element has a first passage which is formed such that in a first position of the valve element inside the inner hole, the first passage connects the fuel inlet with the first outlet channel and in a second position of the valve element inside the inner hole.

    摘要： For a gas turbine engine (10), a method and apparatus for determining temperature of combustion gas in a flow path (17) of the engine. In one embodiment a waveguide (30) includes a cavity (36) with a first waveguide end (32) including a barrier layer (58) which may be a membrane. With the first end positioned to inject an acoustic signal into the flow path, the barrier layer (58) isolates the cavity from combustion gas. Acoustic instrumentation positioned along the surface (38i) of a wall (38) of the waveguide provides generation and propagation of acoustic signals into the flow path for detection and measurement after reflection back into the cavity. The wall may include sections of two different materials, one material having a higher melting temperature than the other, or one material having greater electrically isolating properties than the other section.

    摘要： A gas turbine may include a rotatable shaft, a compressor disposed about the rotatable shaft and configured to output compressed air, and a combustor disposed about the rotatable shaft. The combustor may be configured to receive the compressed air and output high temperature compressed gas. The gas turbine may further include a power turbine disposed about the rotatable shaft and configured to receive the high temperature compressed gas, and a first liner defining a plurality of holes and disposed around the combustor. The power turbine may be configured to expand the high temperature compressed gas and rotate the rotatable shaft. The first liner may have a first end and a longitudinally opposite second end. The first end may be coupled to an inner surface of the casing at or adjacent an upstream end of the combustor and the second end may be substantially free from any connection with the casing.
