Abstract

Способ защиты подводной лодки от широкополосной мины-торпеды, содержащий обнаружение и определение угловых координат в режиме шумопеленгования торпеды, вышедшей из стартового контейнера и наводящейся на подводную лодку, ее классификацию, выработку данных стрельбы, производство выстрела устройства, несущего реактивные снаряды, с приходом устройства в расчетную точку на пути его движения пуск реактивных снарядов, эпицентры взрывов которых, равномерно, исключая образование непораженных участков, распределяются в объеме ограниченного водного пространства, сформированного вокруг предварительно рассчитанной точки встречи устройства и торпеды, путем постановки завес из силового поля взрывов реактивных снарядов на пути движения торпеды в телесном угле, обращенном вершиной к подводной лодке и ограниченном усеченной конической поверхностью с осью симметрии, совпадающей с направлением на источник шума, при этом середина оси симметрии совпадает с расчетной точкой встречи устройства с торпедой, отличающийся темчтоопределяют дистанцию от подводной лодки до торпеды методом активной гидролокации, при этом излучают зондирующий сигнал и принимают отраженный от торпеды (гидролокационный) сигнал с помощью узконаправленной антенны, акустическую ось которой устанавливают в направлении на торпеду, предварительно определенном методом шумопеленгования, а дистанцию Dот места выстреливания устройства-носителя реактивных снарядов до расчетной точки встречи с торпедой определяют по формулам:;,где V- начальная скорость устройства-носителя реактивных снарядов;V- скорость хода устройства-носителя реактивных снарядов;A method of protecting a submarine from a broadband torpedo mine, comprising detecting and determining angular coordinates in the mode of noise detection of a torpedo exiting the launch container and pointing at the submarine, classifying it, generating firing data, firing a device carrying rockets with the arrival of the device in the design point on the path of its movement launch of rockets, the epicenters of the explosions of which, evenly, excluding the formation of unaffected areas, are distributed in a volume limited to one space formed around a pre-calculated meeting point of the device and the torpedo by placing curtains from the force field of rocket-blast explosions in the path of the torpedo's movement in solid angle facing the top of the submarine and bounded by a truncated conical surface with an axis of symmetry coinciding with the direction to the noise source while the middle of the axis of symmetry coincides with the calculated meeting point of the device with the torpedo, differing in that they determine the distance from the submarine to the torpedo active sonar, in this case, a probe signal is emitted and a signal (sonar) reflected from the torpedo is received using a narrowly directed antenna, the acoustic axis of which is installed in the direction of the torpedo, previously determined by noise detection, and the distance D from the firing point of the rocket carrier device to the calculated meeting point with a torpedo is determined by the formulas:;, where V is the initial speed of the rocket carrier device; V is the speed of the rocket carrier device;
