The Quasi-Continuous Method (QCM) which was original]y applied to the steady planar thin wing problems possesses both advantages of continuous and discrete loading methods. The QCM has been successfully applied to steady propeller problems. In the present paper, the QCM is extended to the unsteady propeller problems. First, explanations are made on unsteady two-dimensional wing problems for the evaluation of the validity of numerical method and then a numerical procedure to solve unsteady propeller problems is described in detail. It is then shown that the fluctuating thrust of one blade and propeller vibratory shaft forces calculated by the present method agree well with experiments. Further, an example of calculation is shown for pressure contours on blade surface varying with angular position of a propeller blade in nonuniform flow.
