UNIVERSAL DIAGRAM OF STEERING CAPABILITIES OF AMPHIBIOUS VEHICLES AFLOAT
Using the regression analysis method, the distribution surfaces of relative estimated parameters of steering capabilities of amphibious vehicles afloat (diameter of gyration and turning rate) are calculated and constructed depending on the Froude number and relative yaw moment. These distribution surfaces are a universal diagram for evaluating the steering capabilities of amphibious vehicles afloat. Using the control points of the diagram, one can evaluate the steering capabilities afloat of existing and being designed amphibious armoured vehicles.
