GE Aviation The CF34-8C5B1 is the most recent member of the CF34 The CF34-8C5 is an advanced 14,500 pound thrust engine family to be certified for Bombardier applications. class turbofan propulsion system that powers the 90-passenger Bombardier CRJ900 Series airliner, 100- passenger Bombardier CRJ1000 Series airliner and Series airliner and Bombardier Challenger* 870 business Bombardier Challenger 890 business aircraft. The engine aircraft. It replaces the CF34-8C1 initially delivered on features 50% more thrust, higher thrust to weight ratio, over 200 CRJ700 aircraft. With minimal changes, the lower specific fuel consumption, reduced number of parts, CF34-8C5B1 is fully interchangeable with the CF34-8C5 and improved maintainability and component lives as on either the CRJ700 or CRJ900* aircraft, providing compared to the CF34-3. The engine achieves these optimum value for mixed fleet operations. The dramatic benefits while retaining all the reliability, CF34-8C5A1, delivering an additional 2% NTO thrust, performance and environmental characteristics that have recently entered service on Bombardier CRJ900 aircraft. earned the CF34® family of engines a global reputation for exceptional service on Bombardier Challenger 601, 604 and 605 corporate aircraft and 50-passenger Bombardier CRJ200* Series airliners.
