New trends in the hydrodynamics of high-speed overwater systems

Abstract

For a long time, the debate about the advisability of using rolling bodies on the surface of the water for transport purposes remained purely rhetorical, although the first patent was issued to D. Vanderburg in 1888 [1‒4]. However, in recent years, numerous cases of water skiing on buggies, snowmobiles and motorcycles [5, 6] make us think about the practical use of this idea. The article describes the conditions of water rolling of wheel systems with lugs, the modeling of this phenomenon is carried out, the dependences of the draft and bearing capacity of the wheels on the Froude number are obtained for a number of values of the dimensionless mass of the system, and the position of the boundary of the stable rolling region is estimated.
