Engine manufacturers are showing renewed interest in the 10,000-pound-thrust segment. They see the aging of the General Electric (GE) CF34-3B, the only engine in production in the class, and at least two companies–Snecma and Pratt & Whitney Canada–are eyeing future large business jets, the size of the Bombardier Challenger 600 series, as potential applications. Meanwhile, GE is modernizing the CF34-1 for the Challenger 601.
French engine maker Snecma is here at Asian Aerospace 2006 courting prospective partners and applications for its proposed new SM-X engine. The 8,500- to 10,500-pound thrust turbofan is being offered both for new large business jets and regional jetliners in the 40- to 60-seat class.
