  • Combustion Turbines
    A critical component in combustion turbines used by utilities to generate electricity is the crossfire tube which feeds natural gas to the turbine. This tube contains a packing set which, should it fail, will result in a significant gas leak, requiring shutdown of the unit and repacking
  • Thermal Residual Stress Relaxation And Distortion In Surface Enhanced Gas Turbine Engine Components (.pdf)
    Compressive residual stresses are often deliberately induced in the surfaces of turbine engine components, using a variety of surface enhancement methods, to improve fatigue life. Thermal stress relaxation can occur in both the Ti and Ni alloys used in compressor and turbine stages. Nonuniform
  • Controlled-expansion alloys for turbine engines
    the aircraft operating efficiently, gas-turbine-engine components such as compressors, exhaust casings, rings, and seals must be made of superalloys with low, controlled thermal-expansion characteristics. These materials must provide strength, ductility, and dimensional stability over a wide temperature
  • Cool Coatings Let Engines Run Hotter
    CVD emerges as coating of choice for high-temperature gas turbine components. Howmet Thermatech Coatings, and Alcoa business Design engineers striving to improve the thrust-to-weight ratio, power, and fuel efficiency of gas turbine engines continue to demand higher engine-operating temperatures
  • Case Studies of Fatigue Life Improvement Using Low Plasticity Burnishing in Gas Turbine Engine Applications (.pdf)
    . For successful. integration into turbine design, the process must be. affordable and compatible with the manufacturing. environment. LPB provides thermally stable. compression of comparable magnitude and even. greater depth than other methods, and can be. performed in conventional machine shop
  • ON THE DRAWING BOARD: Hybrid jet to combine turbine and ramjet technologies
    lead to engines seven years from now that have a 25% increase in Mach number, a 250% higher thrust-to-weight ratio, and twice the component life of current, state-of-the-art turbine engines. It might also serve as the initial stage on two-stage spaceplanes that take off like conventional airplanes
  • Southwest Turbine: Innovative Customer Service Through Integrated Manufacturing Technology
    Southwest Turbine designs, manufactures and repairs replacement gas turbine (jet) engine parts for small to medium turboprop and turbofan commercial aircraft engines. Its customers include regional air cargo carriers, commuter airlines, aircraft leasing companies, and engine maintenance companies
  • U.S. Metalcasting Industry is Committed to Greater Energy Efficiency and Environmental Sustainability
    to traditional uses for castings in oil and gas production, castings are essential to renewable-energy sources and more energy-efficient vehicles that demand high-strength, lightweight parts. We're at the forefront developing components for renewable energy, including wind-turbine hubs, bedplates
