Technical FND Operational Aspects  of the High-Speed Vessels Use  in the Russian Federation Transport System

The paper analyzes the methods and formulas for calculating the lift force coefficient Сy of a simple wing with washers from the point of view of the possibility of using it in preliminary design of wing-in-ground-effect crafts. 5 methods were identified that allow calculating the increase in the lift force coefficient from the action of the ground effect. Adequacy was checked by comparing the calculation results for each of the methods with the experimental data of the blowing of 3 variants of the wings in wind tunnels with washers at different aspect ratio, angles of attack and flight altitudes for the TsAGI-876 profile. Also done a numerical simulation of the flow around a rectangular wing with washers with various geometric and hydrodynamic characteristics was carried out. The analysis of the calculated, experimental and numerical results showed that the most expedient use in preliminary design P. A. Amplitov and the method of J. D. Anderson methods. At the same time, one of them is also capable of determining the values of the lift force coefficient in the zone of supercritical angles of attack with an error not exceeding 4-8% for cruising angles of attack of the wing of wing-in-ground-effect crafts.

The article proposes a methodical approach to determine operating costs for a hovercraft. The presented method differs by taking into account the peculiarities of operating hovercraft during the round year. In this case, the methodology allows you to determine operating costs separately for navigation (summer) and internavigation (winter) periods. The article tested the methodology using the example of intracity and suburban routes of the Nizhny Novgorod transport hub. The calculation results were also approximated, the use of which for specific routes will make it possible to quickly find the value of the cost of passenger transportation and the passenger's fare depending on it. The conclusion defines the scope of application of the proposed methodological approach when justifying the costs and size of tariffs for passenger transportation on suburban and intra-city lines, as well as for determining the areas of use and competitiveness of hovercraft compared to other modes of transport.
