6 majors demonstrators tailored to bizjets
2 other have direct applicability to bizjets
Made possible by strong partnership
+ other BLADE partners

This is an essential phase to detail strategy based on shared objectives and designs
A consolidated demonstration path per technology stream is necessary to support this phase From design to individual testing to large demonstrators
Initial Phase: Detailing objectives and
converging strategy
Aerodynamic
Noise Shielding
Flutter
Handling qualities
Acoustic Fatigue
Innovative Aft Bodies

Launch Review
Building a good team of partners takes time
Setting up the worksharing, securing budget
Getting the appropriate number of partners
From challenging global specification to reality
Compromise between desirable objective and technical and budget constrains
Necessary iteration on OEM1 specification to steer the design in enough details

Demonstrations performed successfully in the framework of CleanSky 1, with some delays, despite a number of technical and programmatic difficulties, thanks to the strong involvement of all parties
Comprehensive testing with TRL 5 in CleanSky 1, makes first deployments possible
Further optimization and extension of applicability of part of these technologies is one of the objectives of CleanSky 2
