Description:
The CF34 engine is a derivative of combat proven TF34 military engine, which powers US Air Force A-10 and US Navy S-3 Viking, intended for regional jet aircraft. It has an outstanding reliability, durability and availability specially suited to high frequency routes. Moreover, the engine is considered environmentally safe due to its low noise and smoke emissions. These characteristics make CF34 the engine of choice for 50 to 100 passengers regional jets.
The first CF34 engine entered service in 1983 powering the Bombardier Challenger 601 corporate jet. Since then, it has been selected to power Bombardier CRJ-100, -200, -700 and -900, Bombardier Challenger 601/604, Brazil's Embraer 170/190 family of aircraft, and China's ACAC ARJ21. The engine, rated at 9,220 to 20,000 pounds of thrust, comprises three main models: CF34-3, CF34-8 and CF34-10.
The CF34-10 model is being designed to offer more power for longer range, larger regional jets. The newest CF34 model is rated at 16,000 to 20,000 pounds of thrust. The engine has already been selected to power the Embraer 190 and Embraer 195 (CF34-10E rated at 18,500 pounds) and China's AVIC I Commercial Aircraft Co. Ltd. (ACAC) ARJ21 (CF34-10A). General Electric and ACAC expect that about 500 79- and 99-passenger ARJ21 will be sold in the next 20 years representing $3 billion CF34-10A engines sales.
Key design features are: a wide-chord fan for higher thrust and high tolerance to foreign object damage, 3D aerodynamic design airfoils in the high-pressure compressor providing better fuel burn and higher exhaust gas temperature margins, a highly durable single annular low-emissions combustor, and a single-stage high-pressure turbine for lower operating cost.
On March 9, 2005, CF34-10E, rated at 18,500-lb, was awarded engine type certification by the US FAA paving the way for Embraer 190 certification and entering service with JetBlue Airways in the third quarter of 2005.
