Aeronautics in the Val d'Oise



The Val d'Oise, the cradle of aeronautics, is home to many players in space transport, aeronautic construction and equipment manufacturers, in addition to educational institutions specialising in this sector.

carre The huge economic impact of the aeronautics industry on the industrial fabric of the Val d'Oise can be seen through the presence in the département of prestigious firms with extensive business abroad, including Dassault Aviation, EADS-SECA, Eurocopter, Thalès, Air France Industries.
In addition, the industrial network of equipment manufacturers is particularly strong in the Val d'Oise, with companies such as Goodrich Actuation System SAS, Lisi Aerospace, Axson and Tyco Electronics at Cergy-Pontoise, AIP in Roissy-en-France, Aertec at Villeron and others. The Val d'Oise is also home to a multitude of SMEs which have developed cutting-edge know-how in electricity, sheet metal work, mechanics,

and surface treatment, which all have an important role to play in this industry: Atlas Copco Applications Industrielles and Chromalloy in Cergy-Pontoise, Cefival in Persan, Vue et Cie in Le Plessis Bouchard, for example.
From Roissy Charles-de-Gaulle international airport - a world hub for air transport and freight - to Cefival, the manufacturer of jet engine rings for Airbus A320s, the Val d'Oise spans the entire industry – encapsulated by the ASTech Paris Région competitiveness cluster (see page 4). This cluster's partners include SMEs and multinationals in equal numbers.


« After boosting the region's job market by doubling their payroll to almost 400 employees in their Blanc Aero Industries plant in Cergy-Pontoise, Lisi Aerospace has gone still further by getting involved in the Inosis Project at the ASTech Paris Région competitiveness cluster. »


The CEEVO promotes a number of strategic sectors of excellence in the Val d'Oise, working in partnership with networks of high-performance companies involved in these areas of business, most of which participate in the competitiveness cluster initiative.

carre The « Val d'Oise SAT » club is made up of companies in the Val d'Oise and the Yvelines whose business includes applications or services relating to the design, manufacture or operation of satellites. This network of companies was first formed in 2003, after a meeting between some thirty companies in the Val d'Oise working in this industry and a delegation from the Japanese group of industrialists, ASTRO TECHNOLOGY SOHLA, which is made up of some one hundred specialist companies in Osaka province, Japan. This group of Japanese industrialists has launched a project to create a microsatellite as part of a programme using the resources of SMEs in the Higashi-Osaka urban district, with the support of the local and national authorities.
The « Val d'Oise SAT » club is led by Patrick Robert, head of SYRTEM, who has extensive professional experience in the field of telecommunications. His aim is to encourage experience and information-sharing between members and skill-sharing to gain access to new markets by means of structured offers, as well as taking part in the many European-based programmes relating to the satellite industry (in the United Kingdom, Germany, France, Italy, and Belgium). The members of the Club lead workshops in higher education institutions in the Val d'Oise (including the ENSEA) relating to targeted research. Exchanges also take place with the members of the Val d'Oise Measurement

Network (RMVO) and the GIFAS French aerospace industry association's « Space » Commission.

carre As part of the efforts by the CESE 95 (Val d'Oise Further Education / Company Forum) to bring further education institutions and SMEs and SMIs closer together in the département, the CEEVO is heavily involved each year in the Val d'Oise Research and Innovation Week. A wide variety of events are on offer locally during the course of the week: lectures, visits to factories, companies and research laboratories, business meetings, and so on. Free of charge and open to all, this event is an opportunity to get to know some of the companies and laboratories in the aeronautics industry as well as the projects which are part of the ASTech Paris Région competitiveness cluster. One recent edition, based on competitiveness clusters, offered a series of lectures enabling participants to discover « the aims of the ASTech Paris Région cluster » and presented a completely new « ground-based dual pole radar » project which will allow the inside of clouds to be mapped – a highly useful tool for aircraft pilots.

In order to consolidate its position in the increasingly competitive world economy, France has formed regional competitiveness clusters with a worldwide or national vocation. The aim is to bring together companies, research centres and training bodies to pool skills. They follow the industrial policy already developed in neighbouring Germany and Italy. Each cluster based in the Val d'Oise opens up the département to the world economy.

carre Aeronautics, health, information and communication technologies, transport, energy, finance, and more. The list of the 71 projected clusters, drawn up by the CIADT (Interministerial Regional Planning and Development Committee) covers all the major sectors of business throughout France. With the financial backing of the State, the listed clusters also benefit from tax breaks and reduced social contributions. In addition, local authorities may offer exemption from local taxes.

carre Six of the existing or aspiring world-class competitiveness clusters directly involve companies located in the Val d'Oise: ASTech Paris Région, Cap Digital Paris Région, Finance Innovation, Medicen Paris Région, Mov'eo and System@tic Paris Région.

Receiving the «Competitiveness Cluster» label has an immediate knock-on effect for the «département», enhancing both its brand image and the reputation of its companies, universities and research institutions.



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.
