We have been involved in innovative research, design and construction in the field of aerodynamics, lightweight constructions and GRP composite technology since the foundation of ADC in 1987, with particular focus on wind energy generators. This means aerodynamics and structural design of rotor blades, load calculations with our in-house-tool ADCoS, as well as design and finite element calculations of WEC components like rotor hubs, machine carriers and tubular steel towers. Our employees are engineers with degrees in aircraft and space technology, all with long-standing professional experience in their fields. Since 1998 we have been certified according to DIN EN ISO 9001:2000 in the field of "development and design in aerodynamics, lightweight construction and fiber composite technology".
