In 1992, GE's CF34 engine family helped launch a new era in regional jet aviation. More than 100 million flight hours and 80 million flight cycles later, it continues to set the standard for performance, durability and world-class reliability. Today, the CF34 engine family is in greater demand than ever before, with more than 470 orders in 2013 and record-high production levels. By 2020, more than 7,500 CF34 engines will be powering regional aircraft.
The CF34-8C5 is an advanced 14,500 pound thrust class turbofan propulsion system that powers the Bombardier CRJ900 Series airliner. The engine features 50% more thrust, higher thrust to weight ratio, lower specific fuel consumption, reduced number of parts, and improved maintainability as compared to the CF34-3. The CF34-8C5B1 is a derated version of the CF34-8C5, and powers the Bombardier CRJ700 Series airliner. With minimal changes, the CF34-8C5B1 is fully interchangeable with the CF34-8C5 on either the CRJ700 or CRJ900 aircraft, providing optimum value for mixed fleet operations.
The CF34-10E engine represents a considerable capability increase over the other CF34 engine models. It incorporates the same basic development philosophy and operational features that have earned exceptional market success for the CF34-3 and -8 Series engines: low-risk, proven technology, low operating costs through high reliability, ease of maintenance, best-in-class fuel economy and excellent environmental characteristics.
Since its service entry in 1992, the CF34-3 engine has earned an industry-leading reputation as one of the cleanest and most fuel-efficient engines in its class.
The CF34-8C is the most recent member of the CF34 engine family to be certified for Bombardier applications.
The CF34-8E is an advanced 14,500 pound thrust class turbofan propulsion system that powers Embraer's 70-90 passenger airliners, the EMBRAER 170/175.
GE will provide the total CF34-10A propulsion system for the COMAC ARJ21 - an advanced 18,000 pound thrust class turbofan, with nacelle/thrust reverser and Engine-Buildup Unit (EBU) components.
The CF34-10E is an advanced 20,000 pound thrust class turbofan propulsion system, selected to power the EMBRAER 190/195 and Lineage 1000 aircraft.
