18. Conclusion
STRENGTH SIZE MATTERS
R&D oriented Rotor blades & turbines of the future
Unique expertise in Composites necessitate the re-evaluation and re-
Technology transfer from Aerospace conception of the systems.
Manpower Capacity
Designing in the range of 5-10 MW pushes
Experienced in manufacturing support
technology to the limit. “Scaling” existing
solutions to future size will be neither cost
efficient nor safe. Current skills will be
insufficient.
Leaded by Wind Industry design specialists
A2 Wind is and thinks different. We transfer
know-how from Space, Defense, Aviation for
your next generation of rotor blades and
converters.
