(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 ...

GE Aerospace completed 3,000 test cycles for new, high-pressure turbine blades and nozzles to demonstrate advanced cooling technology. Airfoils were inserted in the core of an F110 engine during an ...

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 ...

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 ...

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.

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 ...

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 ...
