Aeronautical composite sector supported by the New Aquitaine Region with Feder funds for the future Falcon 10X of Dassault Aviation

In order to produce more sober aircraft, the use of composite materials to lighten the wings is becoming widespread among the the main manufacturers of long-haul airliners. The solutions adopted cannot be cannot be applied directly to business jets if we want to obtain a real weight gain, which is a guarantee of weight gain, which is the key to product performance. None of our competitors in the business aviation sector has yet taken this step.

In 2019, Dassault Aviation, supported by the French government’s “Investissement d’Avenir” program and the DGAC, will complete a feasibility demonstration of a composite wing box based on a Falcon 8X.

On the strength of this initial experience, the company has set itself the dual challenge of:

  • to integrate this technology on the future Falcon 10X product,
  • to manufacture this new wing in France.

Such ambitions inevitably entail new technical and industrial risks that had to be overcome as soon as possible. A demonstrator was needed to prepare the industrial sector. The chosen is a full-scale wing box, which must be representative of the industrial constraints of a future industrial constraints related to a future series.

The development and implementation of this field of excellence is mainly carried out at Dassault Aviation sites (Biarritz, Martignas and Mérignac) in the New Aquitaine Region (RNA), and with partners and subcontractors making up the local ecosystem.


The RNA has therefore supported this R&D initiative with the help of the European Regional Development Fund (ERDF).

  •  to carry out elementary tests to characterize the materials;
  • to carry out industrial feasibility tests;
  • to manufacture constituent parts of the box of demonstration and the associated tooling to carry out its assembly.
