Suzlon’s SB 63 blade measures 63 metres in length and has been specifically developed for the S128 family of wind turbines, giving them a rotor diameter of 128 metres, 1.5 times taller than the India Gate. The blade has been engineered with a carbon girder which enables thinner aerodynamic profiles and provides higher lift with less drag. It also incorporates flat back technology at the root that minimises drag and saves additional weight and cost.
The S128 series has been developed to offer 33 percent more swept area (12,860 m2) and is expected to deliver 32 percent more energy generation compared to the S111. This should in turn improve energy yield and support competitive tariff environment in India while protecting customers return on investment.
The new rotor blades will be transported using an innovative two-fold transport system, which will use a specialized ‘Adapter Trailer’ for the first time in India. The aim is to ensure safe and unrestricted manoeuvrability through the country’s hilly terrain while transporting the blades to the most remote areas.
Duncan Koerbel, Chief Technology Officer (CTO), Suzlon Energy, said the SB 63 blade is the longest and most efficient aerodynamic blade Suzlon has ever produced and that the carbon fibre in the new generation of blades simultaneously reduces the weight of the blade and allows the design of even more aggressive airfoils creating a win-win solution for the turbine and Suzlon’s clients.
