CFM International

While General Electric's military engine business for fighter jets was undeniably booming, the American company's ambitions were struggling to materialise in the civil sector. It was not until the late 1950s that GE made its first foray into this market.

On the other side, Snecma has been thinking since the mid-1960s about the best strategy for approaching the civil market with a new engine offering major performance gains in terms of fuel consumption and noise reduction, characteristics increasingly sought after by aircraft manufacturers and airlines.

In 1969, General Electric and Snecma began working together for the first time. Together with the German company MTU (Motoren-und-Turbinen-Union), the two companies produced parts for the CF6-50 engine powering the Airbus A300.

At the same time, and since the mid-1960s, Snecma began conducting a series of thermodynamic, aerodynamic and acoustic studies to establish the main characteristics of the M56 engine. Several objectives were set: low noise level, minimal fuel consumption, reduced maintenance and overall operating costs.

At the same time, the French government drew up its sixth five-year plan, defining the country's economic and industrial objectives for the period 1971-1975. The objectives of the French Aerospace Industry Committee converged with those of Snecma. The company and the government were well aware that the successful development of a 10-ton civil jet engine required international cooperation, for three main reasons. First, although Snecma was capable of developing advanced technologies, it lacked experience, particularly in the development of high-pressure turbines. It didn’t master the technology of variable stators, nor that of small fixed and mobile blades, required for the final high-load stages of the high-pressure compressor. Secondly, domestic sources of supply for high-temperature alloys and foundry and machining technologies for cooled high-pressure turbine blades were limited. Finally, as a specialist in military aircraft, Snecma had neither the sales organization nor the international presence needed to compete in the civil sector.

In 1971, Snecma was looking for a partner to develop, manufacture and sell the future CFM56 engine. The difficulties encountered by the Pratt & Whitney and Rolls Royce development programs quickly left General Electric as the only viable partner. A delegation comprising Snecma Chairman Jacques-Edouard Lamy, Sales Director Jean Crépin and Technical Director Michel Garnier travelled to Lynn, Massachusetts, in April 1970 to meet GE representatives. Gerhard Neumann (head of GE's Aircraft Engine Business Group) understood the scope of this new strategic opportunity in Europe and agreed to a 50/50 partnership.
