Non Intrusive 3D Load Calculation In Yaw Conditions

Explore a non-intrusive method for calculating 3D loads in yaw conditions without force balances or pressure tabs. This study provides insights into rotor aerodynamics and offers means for comparing numerical models. The research emphasizes active load control methods and a stationary frame of reference using solely surface control volumes. Results show good agreement with panel code results and consistent pressure fields, even in non-potential flow regions. The methodology involves measuring wind loads through rotating blade and yaw unsteady formulation, enhancing understanding through absolute and relative velocity fields.
