GE Aviation The CF34-10A is an advanced 18,000 pound thrust class economy and outstanding environmental characteristics turbofan. It is a member of GE’s family of highly successful In addition to drawing upon the proven technologies CF34® commercial jet engines and has been selected to of other CF34 engine models, the CF34-10A also power the new COMAC ARJ21 aircraft family. Although incorporates the very best demonstrated GE and CFMI the -10A represents a considerable capability increase technologies from other large commercial airliner engines, over the other CF34 engine models, it incorporates the including the CFM56, CF6® and GE90®. To ensure that the same basic development philosophy and operational -10A meets the ARJ21’s thrust power requirements for features that have earned exceptional market success for greater aircraft payload and range, the CF34-10A will the CF34-3 and -8 Series engines: low-risk, proven enter into service at 18,000 pounds APR thrust and be technology, low operating costs through high reliability, capable of achieving higher thrust levels for the future. ease of maintenance, excellent fuel GE provides the total CF34-10A propulsion system for the ARJ21, including the nacelle/thrust reverser and EngineBuildup Unit (EBU) components for fuselage mounting.
