the U.S. Department of Energy (DoE) has awarded Pratt & Whitney Rocketdyne US$10.2 million to develop technologies aimed at significantly lowering the electricity costs of concentrated solar power towers and thermal storage systems.

The second hypersonic test flight of Boeing's X-51A Waverider has ended prematurely with the craft failing to transition to full power.

The F-35B short takeoff/vertical landing (STOVL) variant has broken the sound barrier for the first time.

Boeing's X-51 WaveRider has made aviation history by completing the longest ever supersonic combustion ramjet-powered flight.

The D “double bubble” aircraft design promises a 70 percent improvement in fuel economy, reduced noise, lower nitrogen oxide (NOx) emissions and the ability to use shorter runways.

The F-35B Lightning II stealth fighter had completed its first vertical landing.

The US Navy is a step closer to taking possession of its first-ever stealth fighter, the F-35C Lightning II. The aircraft will extend America’s reach and reduce its response time to threat.

By incorporating a gearbox system into the engine, aircraft can achieve a 12% reduction in fuel burn and CO2 emissions, a 50% reduction in NOx emissions, and a 50% reduction in engine noise.
