CF34-10 Engine Testing

CF34-10 Testing

Testing of GE's newest and most powerful CF34 engine, the CF34-10, is ongoing at the GE Test Operation near Peebles, Ohio, leading to engine certification.

The CF34-10E engine is the powerplant for Embraer's new EMBRAER 190/195 regional airliner, scheduled to enter commercial service with launch customer Swiss Airlines in the fourth quarter of 2004.

The CF34-10E is rated in the 18,500 pound (82.3 kN) thrust class. Advanced technology features include: a highly efficient three-dimensional aerodynamic (3-D aero) high-pressure compressor; a single annular combustor (SAC) that reduces oxides of nitrogen (NOx) by as much as 12 percent compared with the NOx emissions of current-technology SACs; a low-solidity high-pressure turbine in which efficiency is improved and the number of airfoils is reduced; and a chevron exhaust nozzle that reduces jet noise.
