  • Aerodynamic measurements on a small HAWT rotor in axial and yawed flow 
    Bellia, J. M. (Cranfield University, 1990-07)
    Current wind turbine performance codes are not yet able to predict the rotor aerodynamic behaviour with sufficient certainty. This has led to both the over-design of blades and to operational restrictions in certain ...
