GE Aviation continues to add CF34 operators to its expanding regional fleet, totaling more than 190 customers across the world. The CF34 engine family recently surpassed 5,500 engine deliveries with more than 82 million flight hours and 66 million cycles.

“For two decades, the CF34 engine has offered our customers unmatched reliability, performance and value,” said Allen Paxson, general manager of the CF34 program at GE Aviation. “We’re building on the CF34 field experience and investing in new component technologies to prepare ourselves for the next generation NG34.”

NG34 Technology Program: The NG34 technology program will incorporate GE’s fuel-efficient, low emission eCore, which will offer 15-20 percent better fuel efficiency than the industry-leading CF34-10E engine. Leveraging GEnx technology, the core will incorporate advanced material, unique cooling technologies and new 3-D aerodynamic design airfoils.

CF34-10E: With the highest thrust rating for the CF34 engine family at 20,000 pounds of thrust, 1,000 CF34-10E engines are in service with 54 operators. The engine continues to perform well in the field, accumulating more than 7 million flight-hours and 5 million cycles. 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 CF34-10E engine powers the EMBRAER 190/195 aircraft as well as the Embraer Lineage 1000 business jet.

CF34-10A: The CF34-10A engine has logged 5,000 flight hours on the Commercial Aircraft Corporation of China (COMAC) ARJ21 regional jet. 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.

CF34-8: The CF34-8 engine has been in service for 11 years, with over 2,000 CF34-8 engines in service on Bombardier’s CRJ700 (CF34-8C1 & -8C5B1) and CRJ900 (CF34-8C5) aircraft and Embraer’s 170/175 (CF34-8E5) aircraft. The engines have accumulated more than 25 million flight-hours and 18 million cycles. The CF34-8 engine design has evolved over the decade with enhancements that 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.

CF34-3: In service since 1992, more than 2,000 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.
