CFM International, the engine manufacturing joint venture between General Electric and Snecma of France, is forging ahead with a range of advanced engine studies as part of its leading edge aviation propulsion (LEAP56) program.
The Franco-Russian Powerjet SaM146 turbofan engine, which is to power the Sukhoi Superjet 100 regional airliner, is set to fly by the end of this month. The first example of the 14,000- to 17,500-pound-thrust family made its first ground run in July 2006 at Rybinsk in Russia.
Snecma is progressing with its plans to develop a turbofan in the 10,000-pound-thrust class. Last October, the French manufacturer revealed plans to enter the business jet engine market. Design of the Silvercrest powerplant is well under way and the core should run later this year.

Brian Rowe, former head of GE Aviation, died February 22. He was 75. Rowe joined GE in 1957 and later led the CF6 engine program. He was named head of GE Aviation in 1979. Rowe launched the CF34 turbofan for business and regional jets, the F110 for the F-16 fighter and the CF6-80C2, which powers the Airbus A300/A300-600/A310 series, the Boeing 747-300/400, MD-11 and Lockheed Martin C-5.
The technical board composed of Sukhoi Civil Aircraft, Boeing and associate member Snecma officially launched the Russian Regional Jet program last month following the completion of a full review of the project’s fourth development phase. The decision arose from meetings between Sukhoi and Boeing executives, who discussed details related to marketing and sales, design and development, production, certification and customer support issues.
French engine manufacturer Snecma has revealed plans to develop a turbofan engine to power business and regional jets. It has started developing a core engine demonstrator called the SM-X that, if a full development program is launched, would yield a powerplant producing between 8,500 and 10,000 pounds of thrust. Ground testing of the core is set for the second half of next year.
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.
Snecma, the leading French aerospace engine and equipment-manufacturing group is no more. A series of moves has transformed it from the government-controlled producer of the successful CFM aircraft engines with General Electric of the U.S. into a private undertaking that last month merged with telecommunications group Sagem to form Safran.
During the Cold War, the Coordinating Committee for Multilateral Export Controls (CoCom) produced the yearly list of items that U.S., European, and Japanese firms were enjoined not to sell to the Soviet Union or any of its client states. The system worked reasonably well, and Soviet military designers were forced to develop their own sophisticated guidance systems, precision machine tools and other advanced technology.
