Abstract:
1 `% @9 w8 I' x% _: H$ p9 v% cAn 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.& e" \! s6 {- q2 m7 h4 E( q+ T
