The Study Of Aerodynamics And Aeroelasticity Model

19721212

Abstract:
. I, u* @/ ]) e# z2 bAn aerodynamic model is development and coupled with a structural dynamic model. The BEM method with the modification of Du-Selig 3-D stall-delay model is adopted to calculate aerodynamic force. The structural dynamic model is an eighteen DOF rigid-elastic beam element including rigid displacements of flap, lag and pitch hinges. Finally, the aerodynamic model is verified and shows good agreement with experiment data.
