SFWA - Rationale Content

• Rationale
• Create the basis for a step change of large
  transport aircraft performance and environmental
  compatibility - with the aim of achieving the
  ACARE 2020 targets - by
• Re-thinking the wing and aircraft architectures
  and components in a fully multi-disciplinary
  approach,
• Validating the best down-selected candidates on a
  representative vehicle(s).
• Content
• Today, innovative technologies, concepts
  capabilities indicate that they have the
  potential to demonstrate a step change in
  critical areas of fuel consumption noise
  emissions.
• They will be pushed forward in a multi-loop
  development down-selection process with a final
  proof-of-concept on large representative
  demonstrators.
• To this end the SFWA platform will integrate an
  Active Wing and Innovative Airframe Concept
  Technologies

SFWA - Impact

• The Platform will provide the most suitable means
  of drawing together current research activities
  at national and European level in a flagship
  project that will pave the way for the next
  generation of European products.
• The Platform will have a leverage effect on the
  future RT investments in the domain of Flight
  Physics. Outside Clean Sky, RT projects will
  be launched to complement the activities and
  reinforce the potential impact of the technology
  on new European products.
• Such a Platform will represent a critical mass of
  activities that enable the step changes.
  Universities, research centres and SME will
  provide the broad range of skill, knowledge and
  competence to design, manufacture, simulate, wind
  tunnel test and flight test the demonstrator.
