February 6, 1995LYNN, Massachusetts - GE Aircraft Engines' CF34-8C turbofan engine has been selected by the Bombardier Aerospace Group - North America to power its proposed new 70- to 76-passenger Canadair CRJ-X regional airliner.
The 13,000 pound thrust class CF34-8C will provide approximately 50 percent more thrust and a thrust-to-weight ratio 15 percent higher than the CF34-3A1 engines currently in service worldwide on the Canadair Regional Jet. The CF34-8C will minimize changes to the installation and the nacelle. GE Aircraft Engines will be responsible for the CF34-8C's complete propulsion system.
"We are extremely gratified by the selection of the CF34 for their proposed new aircraft and look forward to this expanded partnership with Bombardier," said Lloyd B. Thompson, general manager of the Small Commercial Turbofan Department of GE Aircraft Engines. "We have proven to be a very successful combination in the worldwide airline and corporate aircraft markets and look forward to continued success for the CRJ-X program.
"The -8C positions us very well to meet future regional airline propulsion needs, using the same proven technology and experience base."
The CF34-8C will feature a larger fan, higher flow compressor, new low pressure turbine, and a dual-channel Full Authority Digital Electronic Control (FADEC). Selection of the CF34-8C will ease the transition of Canadair Regional Jet operators expanding their fleets with the CRJ-X.
During 1994, the CF34 accumulated 191,000 engine flight hours on 48 Canadair Regional Jet aircraft in service with six airlines, bringing total hours to 258,000 since its 1992 service launch. The engine experienced zero inflight shutdowns during 1994 and had a low shop visit rate of 0.021, or nearly 48,000 engine flight hours between events. CF34-related aircraft dispatch reliability is 99.98 percent.
The low noise and emissions of the CF34 have contributed to the Canadair Regional Jet's reputation as an environmentally "green" aircraft. The more powerful -8C retains all the current CF34's reliability and environmental characteristics and is expected to meet the new anticipated International Civil Aviation Organization (ICAO) requirements on oxides of nitrogen (NOx), hydrocarbons, carbon monoxide, and smoke.
"We are moving ahead on the program in anticipation of a final launch decision that would require us to certify the engine in time to support production aircraft deliveries," said Thompson.
The Canadair/GE CF34 relationship dates back 15 years to the development of the original CF34 engine model for the Challenger 601 business jet. Since its first flight in 1982, the Challenger has logged more than 0.5 million hours with excellent reliability. The engine's military predecessor, the TF34, has exceeded nine million flight hours of service.
