Until recently, high-speed surface vessels consisted mainly of hydrogliders, airfoil boats, hydrofoil and air-cushion craft. Their hydrodynamic characteristics are well understood and the vessels involved have high speeds and excellent sailing qualities. In recent years, however, there has been some expansion of this group of vessels by means of high-speed surface objects on wheels (baggies) and tracks (snowmobiles), in some cases at speeds far exceeding those of hydrofoil and air-cushion craft. Information on the hydrodynamic characteristics of these vessels is not available in the literature. This prompts us to study their hydrodynamic parameters and to consider the practical use of these vessels. The report describes conditions for water rolling of wheeled and tracked systems with grousers, simulates this phenomenon, derives the dependence of draft and bearing capacity of wheeled systems on the Froude number, and presents the dependence of tracked traction on the dimensionless parameter equal to the ratio of absolute speeds of the lower part of a track and the above-water part of a model.

直到最近，高速水面船舶主要由水滑翔机、翼型船、水翼型和气垫船组成。它们的水动力特性是众所周知的，所涉及的船只具有高速和出色的航行质量。然而，近年来，这类船只通过轮子（袋子）和履带（雪地摩托）上的高速水面物体进行了一些扩展，在某些情况下，速度远远超过水翼船和气垫船的速度. 文献中没有关于这些容器的水动力特性的信息。这促使我们研究它们的流体动力学参数并考虑这些容器的实际用途。该报告描述了带抓地齿的轮式和履带式系统的水滚动条件，模拟了这种现象，
