The GE Aviation GE9X engine records the world’s largest fan (11 feet in full diameter) and largest thrust generated and will power the new Boeing 777X aircraft. The GE9X engine was certified by the Federal Aviation Administration (FAA) in September of this year, and GE Aviation has already delivered eight GE9X engines and two spares to Seattle for testing.

GE Aviation and GE Additive are world-leaders and experts in the development of additive heat exchanger applications – from concept through to certification. And together, the two teams used additive manufacturing to develop and certify a servo heat exchanger for the GE9X engine.

GE Aviation’s heat exchangers traditionally have been composed of dozens of thin metal pipes. The 3D-printed heat exchanger for the GE9X has a completely different profile; one that includes optimized channels and complex internal geometries that take full advantage of AM’s design freedoms.

In this webinar, James Bonar, GE Additive’s AddWorks leader focused on new product integration and technology maturation programs, and Curt Hogan, additive technologies design engineer discuss this application in detail, as well as the large opportunity for growth in this market segment.


James Bonar
AddWorks people leader focused on new product integration and technology maturation programs
GE Additive

James Bonar has 10 years of aviation experience at GE. He has executed both new product integration and technology maturation programs. James worked on some of the earliest trade studies at GE in both military and commercial programs to understand additive thermal technologies, and the potential to reduce part counts, increase performance, reduce cost, and change the traditional supply chain. The furthest maturity of these efforts resulted from his leading the additive heat exchanger team through GE9x certification for production. James is a GE Additive AddWorks people leader, and has a Bachelor’s and Master of Mechanical Engineering degrees from the University of Cincinnati.

Curt Hogan
Consulting Engineer
GE Additive

A mechanical engineer who enjoys the details of data. UC graduate with a Bachelor’s and Master’s degree in Mechanical Engineering. Nine years of experience with GE, including five years designing additively manufactured aviation components. Former hardware owner of several NPI’s for GE Aviation including the first aluminum additive heat exchanger certified by the FAA for use on the GE9X engine. Currently a consulting engineer within GE Additive’s AddWorks team continuing to progress the thermal technologies of additive for both commercial and military applications.
