Aeronautics in the Val d'Oise



ASTech Paris Région (a world-class competitiveness cluster) is based on the development of innovation and competitiveness in aerospace-related industries in the Paris region on markets in which it is a world leader: business aviation, space transport and propulsion.

carre ASTech Paris Région focuses on the aeronautics and space industries, fields in which France is a world leader. For this reason, the cluster is extremely important for the Val d'Oise, bringing together top-level companies located in the département, such as EADS, Dassault and Thalès, working together with the CNES1, the ONERA2 and the Ecole des Mines. The cluster, which seeks to encourage a culture of networking amongst local SMEs in order to support the work of equipment manufacturers, is positioned upstream in the industry. It brings together companies supplying manufacturers worldwide (engine manufacturers, flight computing specialists, undercarriage manufacturers, etc.) and industrial players involved with markets which are quite distinct from Airbus (rockets, business aviation, defence, etc.), although their origins are sometimes aviation-related. The research projects generated by the cluster fall within four subject areas: propulsion and

equipment, on-board power supply, materials and structures, and vehicle architecture. The challenge is to enable French industry to take its place in European research programmes on « green planes », which will be lighter, more economical and quieter than current models. ASTech Paris Région also plays a complementary role alongside System@tic Paris Région and Mov'eo. Several accredited projects already feature Val d'Oise companies as partners, including the following:

- SEFORA, with the University of Cergy-Pontoise
- THERMELEC, with Madep (TPE at Cergy-Pontoise).
- RESACOMP, with Axson (Cergy-Pontoise) and Cimpa Airbus.
- INOSIS, with Lisi Aerospace (Cergy-Pontoise).

carre Les Ateliers Laumonier is an SME with 85 employees which has been located in Nesles-la-Vallée in the Val d'Oise since 1923. They design and produce sub-assemblies and finished products for precision mechanics, electronics and computing. They also develop measurement, control-command and communications systems. They manufacture all types of engines and sensors, control and instrumentation amplifiers, including state-of the-art medical apparatus for intestinal chemotherapy. Les Ateliers Laumonier's most prestigious clients include the French Ministry of Defence and the D.G.A. (General Armaments Directorate), Dassault, EADS, Eurocopter, Siemens, SAFRAN, Stago Instruments and Thalès, and more besides. With the emergence of globalisation, the strength of this SME lies in its R&D potential - it brings out several new prototypes each month. Given the wide-ranging influence the ASTech Paris Région cluster is aiming for, there is ample room to accommodate SMEs: they now account for over 30% of organisations in ASTech Paris Région, an increasing proportion of which are being invited to join the leadership committees. This is the context in which Les Ateliers Laumonier decided to concentrate on light aviation. « We can now sell planes in kit form with electric flight controls. Assembly of these controls has become simpler because the cable transmission system has been done away with. Flight behaviour is identical, with increased safety, » explains A. Laumonier, chairman of the Ateliers. It is in this setting that my company is getting involved in projects for Electric Flight Controls used by small 4-5 seater planes for Avyron, who are looking to relaunch production of this type of plane, which they market. This project was very well received when it went on show at the latest international aeronautics and space show at Le Bourget.

carre Cefival, which invented steel extrusion in 1946, is an SME with some one hundred employees and part of the Italian-based Holding group, a European company whose registered office is in Milan. The group's ambition is to become world leader in the manufacture of special profiles (hot rolling, extrusion, stretching, laser welding, etc.). Located in Persan (Val d'Oise), Cefival makes 50% of its turnover from aeronautics, manufacturing jet engine rings, seat rails and some structural components for aircraft including Boeing 737s, Airbus A320s and A340s. « As a long-standing partner of aeronautical engine manufacturers, Cefival has equipped itself with machinery to finish laminated or hot-extruded bars for the industry. The ring department (Editor's note: for jet engines) therefore has high performance bending and flash welding equipment as well as a wide range of presses, enabling each part to be perfectly shaped, » explains Pierre Münch, CEO. Certified by Boeing in 2006 and soon to be certified by Rolls Royce, Cefival is a subcontractor for Airbus, EADS, Areva, the CEA* and Snecma, their number one customer.
Contacts made through the CEEVO (Val d'Oise Economic Expansion Committee) have enabled Cefival to become part of the ASTech Paris Région competitiveness cluster, of which it is a member of the board of trustees and the executive committee. Cefival is deeply committed to this competitiveness cluster, of which it has become one of the three SME representatives.
