Aircraft Engines

Regional Revolution The CF34 sparked one of the most important events in commercial aviation: the introduction of the regional jet. The latest CF34 engine is the CF34-10.

Engine Overview Aircraft readiness, on-time departures, reliability and cost-effective operation are all important measures of a successful regional aircraft engine. Dependability is inherent in the CF34. It is a derivative of GE's rugged, combat-proven TF34 which powers the U.S. Air Force A-10 and U.S. Navy S-3A. The CF34 has evolved from this solid military experience base as a superior commercial engine with excellent performance margin, durability, and a level of reliability that allows today's 50 to 105 passenger regional jets to be flown with utmost confidence throughout the world. The CF34 family is designed with a particular concern for its effect on the total flying environment . . . inside the cabin and outside. The inherently quiet CF34 helps make travel comfortable and more productive. Low noise also contributes to greater operational flexibility. The CF34 is not only a quiet engine, but it is also well within FAA, U.S. Environmental Protection Agency (EPA) and International Civil Aircraft Organization (ICAO) requirements for smoke and emissions. GE is so committed to the CF34, that it has invested more than $1 billion over the last decade.

Solid Performance The CF34-3 launched a new era in commercial aviation and today continues its world-class performance in service around the world.

Engine Overview The CF34-3 incorporates a unique combination of military and commercial airline experience and technology. The resulting in-service performance has proven to meet the dependability and value demands of regional airline customers worldwide. Since its service entry in 1983 on the Challenger 601 Corporate Jet, the CF34 has earned an industry leading reputation as one of the cleanest, quietest, and most fuel-efficient engines in its class. The CF34-3 entered regional jet service in 1992 on the Bombardier CRJ100. CF34 performance provides economy and excellent reliability for high utilization operations comparable to large commercial turbofan engines powering wide-body airliners. The Next Generation Turbofan The GENX is GE's next generation turbofan and will be the workhorse engine of the 21st century for medium-capacity, long-range aircraft. GEnxIn Service: est. 2010 Engine Overview Designed around customers' needs, the GEnx represents a giant leap forward in propulsion technology. The engine will use the latest generation materials and design processes to reduce weight, improve performance and lower maintenance. The GEnx will deliver 15 percent better specific fuel consumption than the engines it replaces, helping operators save whenever they fly. It is designed to stay on wing 30 percent longer, while using 30 percent fewer parts, greatly reducing maintenance. The GEnx's emissions will be as much as 95 percent below current regulatory limits, ensuring clean compliance for years to come, and it will be the quietest, most passenger-friendly commercial engine ever produced. All of the these improvements are thanks to the incorporation of advanced and proven technologies from other engine families and on-going R&D programs. Like lightweight, durable composite materials and specialized coatings. An innovative, clean-burning combustor, a counter-rotating architecture, and a fan modeule that's virtually maintenance free. It is a low-risk, high-value solution to the challenges our customers face everyday. It is the GEnx.
