Zones of steering loses were revealed. Underwater acceleration of the supercavitating vehicle up to march regime was investigated. It was shown that an increase of the starting engine thrust is more effective than the increase of the gas injection into the cavity. Equation for the radius of the slender steady axisymmetric ventilated cavity in ponderable liquid was obtained. It was shown that the gas injection rate is limited by critical values. Examples of calculations are presented. Non-linear analytical solution of the self-similar problem of the expanding wedge penetration into liquid is presented. Cavitating regimes of the jet flows and using the destroy effects of cavitation for the surfaces cleaning, metals cutting, mineral mining, making orifices in metals and concrete.5481 Product Description popup.authors Іванюк Володимир Філімонович Власенко Юрій Дмитрович Каширіхін Леонід Петрович Козенко Олег Миколайович Козенко Роман Миколайович Коозенко Віктор Феодосійович Криницький Володимир Олександрович Маанова Зінаїда Іванівна Нааумова Олена Іонівна Нестерук Ігор Георгійович Савченко Георгій Юрійович Савченко Юрій Миколайович Семененко Воодимир Миколайович Семенов Юрій Асаф"євич Чичик Петро Дмитрович popup.nrat_date 2020-04-02 Close
