Jet fuel burns much hotter than even the toughest alloys, so air injected into the core cools things off. This keeps the engine from melting, but […]

Just like current jet engines are twice as efficient compared to those built in the 1960s, this one, if applied on commercial airplanes, could offer significant savings in fuel and greenhouse gases.

The jet fuel consumption will be reduced by more than 30 percent. In the 80s, NASA and GE designed the engine named GE36, and developed it into a […]

The new turbofan engine also cuts carbon dioxide emissions by 1,500 tons/plane yearly.
