Model CF34-10


More Power

The CF34-10 offers operators more power and reliability for newer, larger and longer range regional jets.


Engine Overview

With the highest thrust rating for the CF34 engine family at 20,000 pounds of thrust, Over 1,000 CF34-10E engines are in service with 48 customers. The engine continues to perform well in the field, accumulating more than 7 million flight-hours and 5 million cycles. The engine includes many advanced technologies, including a single-stage high-pressure turbine, advanced wide chord fan blades, advanced 3-D aero compressor and turbine airfoils, and a chevron exhaust nozzle. The CF34-10E engine powers the EMBRAER 190/195 aircraft as well as the Embraer Lineage 1000 business jet.

The newest variant of the CF34 family - the CF34-10A - was selected by the Commercial Aircraft Corporation of China (COMAC) to power their new ARJ21 regional jet. The CF34-10A received U.S. Federal Aviation Administration (FAA) type certification in July 2010. ARJ21 flight testing is underway. Shanghai-based COMAC is developing the aircraft for Chinese and export markets. It is the first commercial jet aircraft indigenous to China. COMAC has announced orders for 240 ARJ21 regional jet aircraft and forecasts a demand for up to 850 aircraft over the next 20 years.
