“…выполнялась работа, поддержанная государственным заказом № 110-00018-21-00 на 2021 г. В этой работе в качестве основного рабочего органа для предотвращения опрокидывания плота на крутых волнах с опрокидывающимся гребнем предложено использовать якоря присоединенной массы (ЯПМ), а для предотвращения дрейфа -гидродинамические якоря (ГДЯ). Разработано, изготовлено и испытано несколько разновидностей таких якорей; часть из них защищена патентами на изобретения Российской Федерации [1][2][3][4]. Для обеспечения возможности всплывшему спасательному плоту оставаться вблизи места гибели судна разработана конструкция контейнера для размещения плота и его ГДЯ, предваряющая развертывание и начало работы ГДЯ еще до окончания процесса газонаполнения плота [5].…”

The article considers a full-scale comparative experiment conducted in 2020 in the water area of the Novosibirsk reservoir on the simultaneous drift of six marine life rafts with a capacity of 6 people each. Each raft was equipped with one of the developed hydrodynamic anchors (HDA); one raft had a standard parachute floating anchor; one raft had no means of preventing drift. The wing hydrodynamic armature showed good results in reducing the drift velocity. To develop design methods of this kind, hydrodynamic forces were determined in the direct experimental basin of the Siberian State University of Water Transport (SSUWT) by towing with different speeds and angles of attack. According to the tests conducted in the direct experimental pool of the police Department, HDA the coefficients of hydrodynamic forces were obtained. It is noted that the HDA is made in full size, which does not require recalculation according to similarity criteria; the values of the coefficients show an unstable dependence on the towing speed, which is explained by the influence of errors of the experimental method and required averaging of the results. To substantiate the possibility of using the averaging method, the results of numerical modeling of the work of HDA carried out in the Ansys Fluent program are used, which revealed a very weak dependence of the coefficients on the flow rate. On this basis, a decision was made on the possibility of averaging coefficients related to flow velocities v ≥ 0.2 m/s, at which the spread of coefficient values is relatively small. The averaged values of the coefficients obtained in the physical experiment are approximated in their ranges of angles of attack by quadratic polynomials to smooth out the results and facilitate their use in mathematical models of the device operation.

The article is devoted to the urgent task of increasing the effectiveness of rescue operations for the protection of human life at sea by maximizing the drift of rescue vehicles using a hydrodynamic anchor. The paper defines the hydrodynamic characteristics of a hydrodynamic anchor by two different methods: numerical hydrodynamic modeling and physical experiment in a direct experimental pool by pulling a full-scale hydrodynamic anchor with fixed speeds. The identification of the angles of attack of the hydrodynamic armature was carried out in comparison of numerical and physical experiments and the results of calculations of the angles of the working stroke were shown. The angles of installation of the hydrodynamic armature for the angles of attack of the wing, as well as the angles of attack for idling were determined.
