The world’s largest jet engine is being tested for the first time. Being tested near Peebles, Ohio, this is the first working prototype of the GE9X turbofan engine which is so huge that in terms of dimension that GE claims that Shaquille O’Neil would fit inside with Kobe Bryant on his shoulders.
The video shows that the engine is transported to the test facility on board a special truck. At the test facility, it is positioned between two huge blocks of concrete.
Set to power the new 406 seater Boeing 777X mega-plane, combustion and turbine are made of light weight and hear resistant ceramic matrix composites that can operate at temperatures up to 2,400 degrees Fahrenheit.
The engine consists of 16 fourth generation carbon fiber fan blades at the front that supply air to the 11 stage high-pressure compressor. The engine is so massive that just the front fan measures 11 feet (134 inches) in diameter while inlet duct measures 18 feet by 12 feet, thus setting a world record.
Still under tests, the engine will be tested for its aerodynamics, thermal and mechanical factors. The engine has 3D printed fuel nozzles and can generate up to 100,000 pounds of thrust. Other key features include next-generation 27:1 pressure ratio, 11 stage high-pressure compressor besides third generation TAPS III combustor capable of high efficiency and low emissions.
Currently on test at the company testing grounds in Peebles, Ohio, certification and flight testing will commence in 2017 while engine certification is slated for sometime in 2018.
