| The results of experimental researches of movement of models ekranoplans above the wave screen are given. The models of the various aerodynamic schemes are tested. The vertical and angular fluctuations of models are determined at movement above waves of the screen of various length and height. The forces and moments are determined which cause these oscillations. The dependence of these sizes on Struchal's numbers is determined. The ranges of Struchal's numbers are determined, in which the vertical and angular oscillations above waves of the screen arise, and in which they are absent. The estimation of vertical overloads with reference to ekranoplans of the second generation is made at their movement in cruising mode above the choppy surface of the sea. |
