Abstract
Identification of operational loads is useful and applicable not only to the structural design and structural integrity management but also to the active control of the internal loads. The aerodynamic loads are continuously distributed over the aircraft wing and consequently the author's group has been developing a flexible method for interpolating the distributed load to identify the full-field aerodynamic load based on the inverse analysis. The present article reviews the numerical results and application to the wind tunnel tests. Also presented is the coupled inverse analysis of the aerodynamics and elasticity. Attention is paid on the regularization method which is inevitable in order to reduce the adverse effects of measurement error.
