Fluid-structure interaction of the orthotropic rectangular membrane during heaving motion is simulated numerically by using a nonlinear finite element method combined with an unsteady panel method. The numerical results are analyzed to understand the influence of flexibility on the aerodynamic performance of the heaving membrane at a small angle of attack. It is indicated that the amplitudes of the deformations increase considerably as the chordwise and the spanwise elastic moduli decrease, which leads to an increase of average aerodynamic lifts at the cost of the slight decrease of the ratio of average aerodynamic lift to power.
