چکیده

In the current paper, a mathematical model for calculation of transverse pressure distribution on two stepped planing hulls in calm water is presented which can be extended to asymmetric conditions. Base of the developed Mathematical model is similar to Algarin and Taskon [1] and Savitsky [2]. Presented mathematical model divides the two stepped hull to three part and by assuming linearity of separated flow from steps, recognize the wetted surfaces. Finally, using an iterative method, trim angle and resistance of two stepped hull and its pressure distribution whill be obtained. For validation, results of mathematical model will be compared against experimental and analytical data. Effects of boat weight and step height on pressure distribution, wetted surface geometry are also evaluated.
