Here's a look at the benefits and limitations of all-electric, parallel hybrid and series hybrid systems. Aircraft designers have experimented with various forms of electric propulsion for decades.

A hybrid-electric jet engine may seem as absurd as a horse-drawn Zeppelin, but GE Aerospace is ground testing a new megawatt-class hybrid turbofan engine and its full powertrain that is powerful ...

GE Aerospace (GE) on Tuesday said it completed ground testing of a megawatt-class hybrid-electric propulsion system developed under a NASA-funded program, marking a key milestone as the company ...

The U.S. Navy stands at a technological crossroads. The warships that will define American naval power in the 2030s and beyond won’t just carry more missiles or sharper sensors — they’ll be ...

GE Aerospace recently started test running the Passport-turbofan-based hybrid-electric propulsion system it developed under NASA’s Hybrid Thermally Efficient Core (HyTEC) programme, one of several ...

More-electric aircraft (MEA) systems are transforming aerospace design by replacing complex hydraulics with advanced electric ...

Hirect completes acceptance testing of its 6,000 hp locomotive propulsion system, advancing electric traction for Indian Railways and global markets.

GE Aerospace announced it completed testing of a megawatt-class hybrid electric engine system developed through NASA’s Electrified Powertrain Flight Demonstration (EPFD) project, paving the way for ...

The idea of a hybrid-electric engine for supersonic aircraft may elicit a similar initial response, but there is some very firm engineering logic behind it. Put simply, conventional supersonic engines ...
