GE Aviation announced it has completed the initial ground testing of the first full GE9X development engine, the world’s largest commercial aircraft engine that will power Boeing’s 777X. In total, the engine accumulated 167 hours, 213 cycles and 89 starts. The company says the ground testing, which began in April, provided data on the engine’s aerodynamic and thermal characteristics, mechanical integrity, performance and operability.
“This engine is living up to our expectations, and we are extremely pleased with the results,” said Ted Ingling, general manager of the GE9X program at GE Aviation. “During ground testing at GE Aviation’s Peebles Testing Operation, the first GE9X engine performed flawlessly, providing the Engineering team with 1,200 individual data streams that reaffirmed the design. We look forward to the next phase of testing for the engine program.”
The engine will be in the 100,000-pound thrust class and will include the world’s largest front fan (134 inches in diameter), a composite fan case and 16 fourth generation carbon fiber composite fan blades. The engine also features heat-resistant ceramic matrix composite (CMC) inner and outer liners. in Later this year, GE Aviation will conduct ice testing on the first engine to test (FETT) to see how the engine will perform.
