Snecma - SN (France)

The Societe Nationale d'Etude et de Construction de Moteurs d'Aviation-Partenaires (SNECMA), France's largest aircraft engine manufacturer, was created in 1945 to design and manufacture aircraft engines for France. SNECMA was a key player in the global engine market for military and civil aircraft with more than 100 seats. According to its annual report, SNECMA had achieved a 17.5 percent share of this global engine market (excluding the countries of the former Soviet Union) by 1991. General Electric (GE) had about a 36.5 percent share; Pratt and Whitney, a 30-percent share; and Rolls-Royce, a 13-percent share.

Snecma is a company of the SAFRAN Group. Snecma is one of the world's leading aerospace propulsion companies, with a wide range of propulsion systems on offer. By drawing on these different propulsion technologies, Snecma leverages its ability to deliver innovative solutions and develop the multidisciplinary synergies that are critical for tomorrow's air and space power-plants.

In the civil aviation sector, Snecma develops, produces and markets the best-selling family of CFM56 turbofans through CFM International, a joint company equally owned with General Electric. These engines power many different Airbus and Boeing jetliners. Snecma is also General Electric's main partner in the GE90 engine with 25% of the program. In addition, we have a stake in the CF6 and GP7000 engine programs.

Snecma designs, develops and builds military aircraft engines offering world-class performance. For example, the M88 engine that powers France's new-generation Rafale fighter has the highest turbine inlet temperature in the world. Our engines power over 20 different types of transport, training and combat aircraft for 41 armed forces around the world. A military aircraft powered by Snecma takes off somewhere in the world every minute. Snecma leads the team of European companies that make propulsion systems and equipment for other launch vehicles, satellites and space vehicles.

The “Société des Moteurs Gnome” engine company was founded in 1905 in Gennevilliers by the Seguin brothers, who will soon start development of the first rotary engine. In 1912 Louis Verdet founds his engine company, “Société des Moteurs Le Rhône”, and in 1915 Gnome and Le Rhône mergeed to create the "Société des Moteurs Gnome & Rhône". In 1945 French engine manufacturers are consolidated and nationalized under a new name: S.N.E.C.M.A. (Société Nationale d’Etudes et Construction de Moteurs d’Aviation).

In 1974 Snecma and General Electric signed an agreement creating CFM International. The first CFM56 commercial engine order came in 1979. Delivery of the 10,000th CFM56 engine came in 1999. In 2008 General Electric and Snecma signed an agreement extending their 50/50 partnership to 2040. GE and Safran power nearly all single-aisle commercial jets, including the Airbus A320 and Boeing 737 families with the best-selling CFM56.

The new LEAP engine, slated for certifi cation in 2015, has already been selected to power the next generation of commercial jets – Airbus A320neo, Boeing 737 MAX, and China's Comac C919 – thus echoing the success of the CFM56. While the LEAP features a number of technological innovations, it is still based on a proven architecture to guarantee operational reliability as well as optimized and predictable maintenance costs.

Snecma (Safran group) designs, develops, produces, markets and supports jet engines for combat and training aircraft, and turboprop engines for transport aircraft. It works with both the governments that order these products and the armed forces that use them. Snecma engines power more than 20 different types of military aircraft in 40 countries, including the M53-P2 for the Mirage 2000 family, the M88-2 on the Rafale, and the TP400-D6 for the Airbus A400M.

Wholly designed, developed and produced by Snecma (Safran group), the M88-2 powers the Rafale multirole fighter built by Dassault Aviation. It is also the basis of a new family of engines built around a common core. The M88-2 powers both the air force and naval versions of the Rafale multirole fighter. It is a new-generation engine that features cutting-edge technologies such as a low-emissions combustor, single-crystal turbine blades and powder metallurgy disks. The M88-2 also incorporates the latest advances to reduce its electromagnetic and infrared signature. Its modular design enhances maintainability and contributes to high dispatch reliability. Snecma has developed an upgraded version, the M88-2E4, to further reduce specific fuel consumption and augment the lifespan of critical engine parts, in particular the core and afterburner. These improvements reduce fuel burn by 2 to 4%.

Purpose-designed for the Airbus Military A400M transport aircraft, the TP400-D6 is the most powerful turboprop ever developed in the West. The Airbus Military A400M airlifter will be powered by the TP400-D6 turboprop engine, offered by European engine-makers operating through the Europrop International GmbH consortium (EPI). Within this partnership, Snecma (Safran group) is in charge of the combustor, the high-pressure turbine and installation of the engine on the aircraft. Snecma is also responsible for the control system, which has an electronic control unit from Sagem. Other Group companies contributing to this program are Hispano-Suiza, for the gearbox, and Techspace Aero, for the lubrication system.

Part of the Safran group, Hispano-Suiza is a high-tech specialist in airborne power transmission and management, focusing on power transmissions, and electronic power controllers and electrical systems. As a major player in the enabling technologies and systems needed for “more electric” aircraft, we aim to become a world leader in the entire electrical energy system on aircraft. The name “Hispano-Suiza” still sets pulses racing because of the company’s legendary history in both automobiles and aviation. For more than a century now, whether in France or abroad, this brand has evoked an image of performance, quality and innovation, qualities that are just as much in evidence today.

Automobile manufacture came to an end in 1936, as Hispano-Suiza concentrates on the production of aircraft engines and builds a wind tunnel in Bois-Colombes for engine testing. After the war, Hispano-Suiza was determined to resume its business as an aircraft engine manufacturer. It acquired a license from Rolls-Royce to manufacture the Nene jet engine with centrifugal compressor (which will power the Mistral and Ouragan), followed by the Tay. In 1968 joined Snecma, and its Bois-Colombes plant became a division of the company.
