A multi-rotor wind turbine trialled by Vestas recently produced its first kilowatt hour. This experimental four-rotor design is being tested with the ultimate aim of creating multi rotor systems for large unit capacities offshore.
In support of research into multi rotors Aerotrope worked together with GL Garrad Hassan and Peter Jamieson (author of “Innovations in Wind Turbine Design”) on engineering of the OWES 5-MW. We engineered the support structure and yaw system for this experimental 16-rotor array. The idea was to come up with an efficient support system that would counteract cost penalties.
