The flow field around an elastic body is treated as a fluid-structure interaction problem and has been investigated by experimental and numerical approaches. Many researchers have already reported the characteristic of dynamic thrust acting on an elastic moving airfoil at 0 degree of angle of attack and their wake structures. In this study, we investigate the characteristics of dynamic forces acting on elastic heaving airfoil in a separation region, at 16 degree of attack angle, and the dynamic behavior of the vortices rolled up from the leading edge by fluid structure interaction simulation using ANSYS 16.1/ANSYS CFX 16.1. The generation and the growth of the leading edge vortex in the elastic airfoil delay slightly than that in the rigid airfoil due to the effective angle of attack.
