ANALYSIS AND PROSPECTS OF DEVELOPMENT OF HIGH-SPEED SHIPS
The classification of high-speed ships is carried out. Criteria of their comparative assessment are defined. It is shown that the Froude for normal ships and the gliding ships Froude number characterizes the proportion of dynamic component of the total force maintain. For hydrofoils, hovercrafts and multi -hull ships, this criterion allows the zones of their effective operation to be established taking into account the main design characteristics- tonnage and speed of travel. It is shown that gliding ships are the simplest, cheapest and most common. In these cases, spontaneously there are increasing vertical and angular deviations, as well as fluctuations in the longitudinal and lateral planes. Hydrofoils are the most common and developed type of high-speed ships. Recommendations to improve the seaworthiness of hydrofoils. The classification of parameters determining the appearance, navigation and seaworthy characteristics of hovercraft skegs. Different ways of moderation of swings of pitching and overloads based on regulation of pulsations of air pressure in air cushion are analyzed. Advantages are specified, the main characteristics of amphibious hovercrafts are listed. The design parameters having the greatest influence on running characteristics of amphibious hovercrafts are established. It is claimed that high-speed catamarans are the most rapidly developing type of ships. Technical solutions aimed at improving the performance of catamarans are formulated. Advantages and disadvantages of layout schemes of ekranoplans are marked, their classification is executed. The problems of take-off/landing of the device, as well as the principles of its longitudinal and transverse stability. Ways of the solution of the revealed problems are listed. The characteristics of high-speed ships of different types in the system of formed criteria are compared. The ranges of rational use of different types of high-speed ships are revealed.
