Using turbulence to keep dams clean

Sediment builds up in reservoir water and can prevent dams from operating properly. EPFL researchers have come up with a method of keeping sediment in suspension and allowing it be flushed out.

Don't build your model on sand

Volcanic ash can damage jet engines, and Ludwig-Maximilians-Universitaet (LMU) in Munich volcanologists have developed a new empirical model for assessment of the risk. Their results show that tests using sand do not reflect ...

Jet engines to become cleaner in future

Thanks to a close collaboration between the Swiss Federal Laboratories for Materials Science and Technology (Empa), SR Technics and the Federal Office of Civil Aviation (FOCA), Switzerland is setting an international benchmark ...

Testing turbines to save energy

They say a little knowledge is a dangerous thing. But a little knowledge can also be comforting. For anyone who has sat on a jet airplane at takeoff, tense and sweaty-palmed, wondering how in the world this gigantic assemblage ...

Researchers developing high-flying jet car

It's dark and late. You're speeding through the streets of a downtown metropolis. You're being chased and the pursuers are quickly gaining ground. With a knowing smile, you simply press the 'launch' button of your jet car ...

Team develops device to detect biodiesel contamination

In 2010, a Cathay Pacific Airways plane was arriving in Hong Kong when the engine control thrusts seized up and it was forced to make a hard landing—injuring dozens. The potential culprit? Contaminated fuel.

Faster, better, safer jet engines

From Igor Sikorsky's first American helicopter to Pratt & Whitney's latest engine for the nation's new Joint Strike Fighter jet, Connecticut has a proud history of aviation science innovation.

Researchers seek to reduce ear-splitting jet engine noise

Have you ever had a fighter jet fly over your home and the noise of the aircraft booms loud enough to rattle the windows? Well, imagine working on an aircraft carrier or air base, up close to the engines as they take off ...
