Strong orders power CF34 program to new heights
- Engine nears 100,000 million flight hours
GE Aviation received firm orders for more than 350 CF34 engines since December 2012. CF34-powered aircraft orders include:
- Seven firm E190 orders from Conviasa (June),
- 40 firm E175 orders from SkyWest (May),
- 30 firm E175 orders from United Airlines (April),
- 47 firm E175 orders from Republic Airways (January),
- Five E175 and 15 E190 aircraft from Aldus Aviation (January),
- 40 firm Bombardier CRJ900 Next-Gen Aircraft from Delta (December) and
- Two E175 orders from Fuji Dream Airlines of Japan (December)
The CF34’s growing production backlog is expected to help increase the total in-service engine fleet to more than 7,600 engines by 2020.
“Orders from several North American regional jet operators resulted in a strong year for the CF34 program,” said Allen Paxson, general manager of the CF34 Engine Program at GE Aviation. “For more than two decades, the CF34 engine has offered our customers unmatched reliability, performance and value. We look forward to building on that legacy for many years to come.”
The Global Homeland Security Market 2012-2022
GE has delivered more than 5,800 CF34 engines since it entered service in 1992. The CF34 engine is in service with 200 operators in more than 70 countries. The engines have accumulated more than 97 million flight hours on Bombardier CRJ and Embraer E-Jet aircraft, and they have set the standard for dispatch reliability of 99.95%.
The CF34-10E engine is the highest thrust rating for the CF34 engine family at 20,000 pounds of thrust, with more than 1,300 CF34-10E engines in service with more than 60 operators of Embraer's E190/195 aircraft and the EMBRAER Lineage 1000 business jet. The CF34-10E 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 engine is still early in its lifecycle with the first production engines beginning to visit service facilities for their first shop visits. The engines have accumulated more than 11 million flight hours and 7 million cycles.
The CF34-10A engine continues to flight test on the Commercial Aircraft Corporation of China (COMAC) ARJ21 regional jet. About 20 GE engineers and field service support are assisting in the aircraft certification program. GE has also established an engine line maintenance training course at its Customer Training Center in Shanghai. COMAC has announced orders for more than 250 ARJ21 regional jet aircraft and forecasts a demand for up to 850 aircraft over the next 20 years.
More than 2,100 CF34-8 engines are in service with more than 70 operators of Bombardier CRJ700/CRJ900s (1390) and Embraer's E170/175s (780). The CF34-8 engines has evolved to provide greater thrust capability with lowered part count, improved durability and reduced maintenance costs. The CF34-8C1 upgrade to incorporate technology from the CF34-8C5 version to create a common engine for the CRJ700 and CRJ900 is complete on the fleet. The upgrade provides either up to 5 percent thrust increase or up to 15 percent lower maintenance costs. The engines have accumulated more than 29 million flight-hours and 21 million cycles.
CF34-3: GE Aviation's CF34-3 engines helped launch a new era in aviation when it entered service on Bombardier's CRJ100 aircraft in 1992, spawning the beginning of regional jet segment in commercial aviation. Close to 2,300 CF34-3A1 and -3B1 engines power the Bombardier CRJ100/200 aircraft. An upgrade package can convert the CF34-3A1 to a CF34-3B1 to improve fuel burn and climb thrust capability.
