World’s largest jet engine
The GE9X, the largest jet engine ever built, has started its certification testing at GE Aviation’s bootcamp for jet engines in Peebles, Ohio.
The pre certification testing of 168 hours of bombardment with ice, the exposure to dust and debris that simulated 3,000 takeoffs and landings was carried out.
When testing is complete, the GE9X will be approved by the FAA to fly on commercial jets.
8 engines will be used
The engine now on the test bed is nicknamed SETT, or second engine to test. The third engine is currently being built at GE Aviation’s headquarters in Evendale, Ohio and and a fourth will be installed before the end of the year on GE’s 747-400 test bed in the Mojave Desert. In total, eight GE9X engines will be used in the certification program.
The engine will feature fourth-generation carbon fiber fan blades and a fan case, 3D-printed fuel nozzles and lightweight materials called ceramic matrix composites. The combination of these components decreases engine weight, boosts efficiency and will decrease fuel burn.
Will Power Boeing 777
The GE9X will power Boeing’s next-generation 777X passenger jet, and nearly 700 GE9X engines already are on order.
