The researchers noticed that, keeping the air flow from the compressor steady, the flame jet in the tube appeared to lengthen when the microwave power was increased. They set about trying to measure ...

A modern jet engine is a complex mechanical wonder. However, these aren't engines that will just roar into action with the turn of a key or the press of a button. Often, turbine engines will need ...

DARPA has awarded a contract to Aurora Flight Sciences to build a full-scale aircraft called the X-65. It will test a new technology that replaces moving control surfaces with Active Flow Control (AFC ...

Sep. 18—Jet-engine manufacturer Pratt & Whitney has been awarded an approximately $670 million contract modification from the U.S. Department of War for additional production of F135 engines for F-35 ...

The search for new solutions for engine ignition systems and combustion of lean air-gas mixtures has led to the application of a two-stage combustion system, previously also known as turbulent jet ...
