Choice of rational mutual positioning of bearing surfaces of "Duck" scheme airfoil boat

Determination possibility of rational mutual positioning of bearing surfaces positioning of «duck» scheme airfoil boat is considered by analytical methods. The approach which is different from traditional, exactly,the possibility of aerodynamic quality of bearing system increase not for of a carrying power, but for reduction force of front resistance of bearing system force is used. The assumption possibility of the analytical methods application unity that allows essentially to simplify essentially the search of the decision at qualitative level is taken out that in turn will allow to reduce the quantity of experiments, including virtual, to receive required results.
