General Electric CF34-10A
General Electric CF34-10A exact turbofan model in the CF34 family. GE's CF34-10A datasheet lists 17,640 lbf (78.47 kN) maximum takeoff thrust with APR, a 5:1 bypass ratio, a 29:1 maximum overall pressure ratio, and a 2011 engine entry-into-service milestone. GE later reports the CF34-10A-powered ARJ21-700's first commercial flight in June 2016; the existing COMAC ARJ21 family relationship remains separate from this propulsion identity.
