GE Pushes Ahead with Engine For 777X

General Electric is stepping up studies to provide a new engine for Boeing’s planned 777X. GE90 program manager Bill Millhaem has confirmed that the proposed GE9X turbofan will deliver 10 percent greater fuel efficiency than existing engines in the family.

The U.S. engine maker expects to achieve a first run of the high-pressure compressor rig early in 2013. The first test of the full core should be achieved by 2015.
