• The performance of screw propellers in unsteady flow and the stress distribution and deflection of their blades are computed by surface panel method in combination with the thick shell finite element method, and compared with the experimental results. The characteristics of the surface flows on rigid and deflected blades are approximated by Taylor's series expansion and minimization of the kinetic energy of perturbation velocities. A new method also is applied to estimate the time derivatives of the perturbation potential on the basis of a minimization of the change of its kinetic energy. The comparison between calculated and measured data for pressure distribution confirms the reliability of the estimation of unsteady characteristics at tip of the propeller.
