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 ...

The integrity of the turbine blades in an aircraft engine is crucial for safe operation. The turbine blades are exposed to a multitude of stresses during the engine’s operation cycle, including rapid ...

UK engine maker Rolls-Royce is pushing ahead with advanced turbofan engine designs for future platforms, with greatly improved efficiency. Titanium-aluminide low-pressure turbine blades and proposed ...

Not long ago, thermoplastic composites (TPCs) were heralded as the future of wind turbine blades. Recyclability, ease of repair and, especially, short mold cycle times made TPCs very attractive to ...

Recent-model large-frame gas turbines have experienced some growing pains, but modifications and upgrades have increased their reliability substantially. Due to low natural gas prices, low capital ...

Siemens has finished its first full-load engine tests for gas turbine blades completely produced using Additive Manufacturing (AM) technology. The company successfully validated multiple AM printed ...

Demand for electricity from artificial intelligence (AI), data centers, industrial electrification and more is driving ...

Manufacturers of gas turbine engines are experimenting with higher operating temperatures to improve engine efficiency. Working with the support of GE, Iowa State engineers are developing new tests ...
