GE Pleased With Progress On GE9X HPC Tests

GE Aviation this week reported that testing on the high pressure compressor (HPC) module for the GE9X engine that will power Boeing’s 777X aircraft continues to yield “very promising results,” achieving a 27:1 pressure ratio–the highest of any commercial aircraft engine. The tests began in September at the GE Oil & Gas testing facility in Massa, Italy, and the module has accumulated close to 300 hours of testing today.

“The testing has validated the efficiency and operability of the HPC module design well ahead of the entry into service and supports our plan to deliver a 10 percent fuel burn improvement over today’s GE90 engines,” said Bill Millhaem, general manager of the GE90/GE9X program at GE Aviation.
