AMES, Iowa – Engineers know that gas turbine engines for aircraft and power plants are more efficient and burn less fuel when they run at temperatures high enough to melt metal. But how to raise ...
Cylindrical holes were once the industry standard for air film cooling on turbine engine components. The cooling holes were traditionally formed using an electro-discharge machine (EDM) with a round ...
Pre-swirl systems are a critical component in modern gas turbine engines, designed to condition the cooling airflow before it reaches the turbine rotor blades. By imparting a controlled rotational ...
Proper air filtration is critical to the overall performance and reliability of gas turbines. Fuel costs approach 80 percent of the life cycle cost of electricity. Small gains in efficiency can mean ...
