Abstract: FIELD: shipbuilding. 
     SUBSTANCE: invention relates to ship building, particularly, to design of single-hull high-speed vessels. Proposed vessel comprises housing with smooth curvilinear outlines of hull underwater part and with maximum width of structural waterline in stern part. Vessel nose end has sharp lines – nearly straight waterlines with light bulge with inlet angle of about 10° – in combination with small splinting of frames: angles to vertical of 1–3 of theoretical frame timbers change from 17–22° in waterline area to 26–27° in the area of breakage of the board, above which the frame timbers sharply decreases down to the reverse one. Hull volume displaced to stern; waterlines are expanded to 14–15 theoretical frame timbers, smoothly passing into a section of the board with constant width, which is retained to the transom. Vessel height in transom area makes about 3.5 % of length between perpendiculars. Small frame timbers collapse combined with waterline sharp nose branches provides for “wave breaking” qualities of ship in conditions of developed roughness. 
     EFFECT: technical result consists in improvement of nautical qualities of ship with simultaneous provision of sufficient capacity and stability, providing high speed and enabling use of weapons and armament in conditions of developed sea waves.

Filed: 2020-03-13
Granted: 2020-08-05
Abstract: Способ измерения дальности относится к области техники радиотехнических средств измерения расстояния и может быть использован, например, для измерения дальностей в локальных навигационных системах при управлении движением надводных объектов при контроле их плавания в прибрежной зоне, захода и прохода по бухте, организации автоматического причаливания. Новым в способе измерения дальности является использование одновременно двух каналов передачи информации. При этом опорный низкочастотный сигнал передается с одного конца измерительной трассы на другой посредством модуляции, передачи и демодуляции радиочастотного сигнала. При этом излучение и прием радиочастотного модулированного сигнала осуществляется над водной поверхностью. С помощью этого канала на обоих концах измерительной трассы формируют синфазные непрерывные низкочастотные колебания. В качестве основного информационного используется акустический канал связи, организованный акустическими преобразователями, располагаемыми под водной поверхностью. Собственно набег фазы акустических волн является информационным параметром определения расстояния. Последовательным изменением частоты непрерывных колебаний низкой частоты и сопутствующим измерением разности фаз сигналов в модулированном радиочастотном и акустическом каналах однозначно определяют дальность в локальной навигационной системе. 2 н.п. ф-лы, 2 ил.
