D1-3 Flap Demonstrator

D1-3

High-lift inner flap assembled in full demonstrator

 
  • Upper cover Liquid Resin Infusion (LRI) integrating leading edge and trailing edge (ALESTIS).
  • Lower cover in Thermoplastic In Situ Consolidation (TP-ISC) with welded thermoplastic centre spar (ACIENG and FIDAMC).

Innovation Objectives achieved:         
Demonstrated novel manufacturing processes and concepts for highly integrated structures:

  • Multi-spar concept.
  • Leading-edge upper cover integration to understand challenges of its applicability to natural laminar flow.
  • Maturation of highly integrated one-shot manufacturing processes.
