Video of the week: Ground tests start on world’s largest commercial aircraft engine

This week’s video comes from Ohio where ground tests have begun on the world’s largest commercial aircraft engine.

GE Aviation’s GE9X is a 100,000 pound thrust class engine that is going through its paces at the company’s Peebles Test Operations facility prior to initial deployment on Boeing’s new 777X aircraft.

According to GE Aviation, the GE9X engine will have the largest front fan at 134 inches in diameter with a composite fan case and 16 fourth generation carbon fibre composite fan blades.

Other key features include an 11-stage high-pressure compressor; a third-generation TAPS III combustor; and CMC (ceramic matrix composites) material in the combustor and turbine.
