Recommendation from past reentry programmes
Priority for In-Flight research with emphasis
on reduction of uncertaintiesassociated with

• Transition ( Roughness induced/shear layer)
• SWBLI flap efficiency
• Shear flows, Base flows
• Real gas Chemistry
• Catalysis and oxidation
• Measurement Techniques integration
• Windtunnel to flight scaling

ISTC framework first Conclusion

• Unprecedented Collaboration between Europe and
  Russia in the field of in flight research for
  Aerothermodynamics and Thermal Protection gas
  surface interactions covering
• Numerical activities
• Windtunnel testing experimentation
• Flight testing
• Thanks to ISTC direct and personnel relation
  ships could be build up providing the thrust
  level and collaborative environment to exchange
  information and develop together new ideas .
  Examples of spin offs are Rad flight, Polyspheres
  and Aeroassist.

What to be improved

• ISTC should provide funding for collaborateurs
  allowing the interactions between scientists to
  take place this building up of thrust between
  scientists was the essence of the success of
  EXPERT
• Shorter decision making process both for Regular
  and Partnership contracts
• Organize more of the presently held workshop
  events thereby harmonizing with other activities
  and getting new ideass and contacts
