A jet stream is caused by oscillating an elastically airfoil and propulsion occurs. This propulsion is related to the modulus of elasticity. But until now, there is not an analysis with considering interaction between the elastic object and fluid. In this papar, we developed FDM-FEM coupling method wichi is satisfied with conservative of momentum. And we investigate the relationship between the modulus of elasticity and the velocity of a jet flow for airfoil by numerical analysis. Moreover, we investigate the relationship between the modulus of elasticity and the velocity of a jet flow for plate by numerical analysis. By compare the velocity increment obtained in the each result in these two cases, there is an interesting finding.
