In this report an anlysis is made of measured load aerodynamic loadson wind turbine blades at yawed conditions. The measured loads are compared with results from the wind turbine design code PHATAS-IV. The aerodynamic model in PHATAS-IV is based on the blade element momentum model, with correction formula for yawed conditions. The measured data are also compared with the results from the newly developed free wake lifting line model AWMS.
