(Phys.org) —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 ...

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 ...

The impact of airborne particulates on aircraft engines is a huge challenge for today’s aviation industry. When hail, ice, heavy rain, dust and sand, volcanic ash, lightning, or corrosive gases enter ...

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 ...

The long lead time for the development of blades and vanes used in gas turbines, such as in power stations, presents a significant challenge to the validation of new part designs in engine tests.

Eric Wan, Turbine Technology International, and Steve Hoffman, Hoffman Publications Inc. More and more turbine owners are using software to guide life management decisions for turbine hot section ...

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 ...

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 ...
