The aim of this study is improvement of negative torque in returning blade . The rotor is constructed by 16 blades ( chord length are l55 % of diameter ) . The equations are discretized by Finite volume method fbr space and Fractional step method f { ) r time. As a resuit of analysis , thc best shape was flat plate , and its
