Aerosystems is closely associated with leading universities in Prague and Brno and has a strong relationship with Compotech, fabricator of carbon fibre. Advances in carbon fibre technology allows us to prototype the fabrication of whole units including impellors (rotors) and ducts, utilising filament-wound shafts for propulstion. It has enabled us to develop and manufacture extremely light units (under 30 kilograms). Testing All parts and structures are subject to rigorous testing both statically and dynamically.
