RESISTANCE OF HOVERCRAFT PLATFORMS IN THE FIELD OF FINELY BROKEN ICE
The motion of the hovercraft platform in microfine layer of broken ice is considered. The solution of the plane problem on the interaction of a plane contour composed of the surface of the flexible protection with broken ice is given. The analytical data for the constituents of the medium resistance while the platform moving are obtained. The special experiments with a platform model in the pool covered with a layer of polyethylene granules, simulating finely broken ice, are described. The curves of resistance are shown. The model tests and the results of calculations showed satisfactory convergence of the results.
