В работе рассматриваются варианты улучшения ходовых характеристик малого автономного необитаемого надводного аппарата осмотрового класса. Аппарат был разработан и построен в ФГБОУ ВО СПбГМТУ. В процессе опытной эксплуатации аппарата были обнаружены проектные недостатки: аппарат «тяжело» проходил по заданному маршруту в условиях ветра и волнения. Для анализа динамики аппарата было произведено экспериментальное и численное исследования, по результатам которых сформированы рекомендации по выбору формы корпуса, состава и расположения движительно-рулевого комплекса и компоновки электроэнергетической системы аппарата. В качестве рекомендуемой формы корпуса были выбраны обводы с круглой скулой и туннельным типом кормовой оконечности, позволяющие не только снизить полное сопротивление на рассматриваемых скоростях хода в сравнении с другими вариантами обводов, но и защитить движительных комплекс от внешних воздействий во время эксплуатации. При анализе работы движительной установки было обнаружено, что установленные электродвижители работают на нижнем пределе своих возможностей. Для достижения желаемых ходовых показателей необходимо увеличивать напряжение электроэнергетической системы. Для анализа применимости предлагаемых мер были выполнены расчеты в программе численного моделирования гидродинамики OpenFOAM и проведены экспериментальные исследования в опытовом бассейне. Согласно полученным результатам предложенные варианты модернизации можно считать успешными и рекомендуемыми при дальнейшей разработке и модернизации аппарата.

The paper considers options for improving the propulsion characteristics of a small autonomous inspection class unmanned surface vehicle (USV). The USV was designed and built in SMTU in St. Petersburg, Russia. During the lake and river trials of the USV, design defects were discovered: the device passed hard along a given route in wind and waves conditions. The experimental and numerical studies carry out to analyze the dynamics of the USV. Based on the results recommendations form for choosing the hull shape, the composition and location of the propulsion-steering complex and the layout of the electric power system. The contours with a round chine and a tunnel type of aft end choose as the recommended hull shape, which allows not only to reduce the total resistance at the considered travel speeds in comparison with other hulls, but also to protect propellers from external influences during operation. It founds that the installed electric motors operate at the lower limit of their capabilities. To achieve the desired running performance, it is necessary to increase the voltage of the electric power system. For analyse of applicability of the proposed measures the calculations perform in the CFD program OpenFOAM and experimental studies carry out in the towing tank. According to the results obtained the proposed modernization options can be considered successful and recommended for further development of the device.

В статье приводятся данные о поиске объектов подводными аппаратами. Проведён анализ физических основ подводного поиска, включающий исследование таких его составляющих, как средства обнаружения носителя информационно-измерительных и управляющих систем, морская среда и собственно объекты поиска. Направление этих исследований включало выявление особенностей функционирования бортовой аппаратуры подводных аппаратов в таких физических полях, как гидроакустическое и световое. В качестве одного из главных условий обнаружения целей в гидросфере предложено использовать информационно-измерительные и управляющие системы подводных аппаратов на выявление собственных физических полей объектов поиска, отличных по своему характеру от аналогичных полей окружающей среды. Исследовано распределение плотности вероятности значений сигналов и помехи в гидроакустическом поле. Обосновано, что для выявления объекта поиска в зоне действия, то есть видимости бортовых измерительных систем, необходимо и достаточно выявление наличия локальной неоднородности гидросферы, формируемых целями. Предложены системы, реализующие это условие.

The article provides data on the search of objects by underwater vehicles. An analysis of the physical foundations of underwater search, including the study of its components, such as the tools of detection of information-measuring and control systems, the marine environment and the search objects themselves, was carried out. The direction of these research included revealing of features of functioning of onboard equipment of underwater vehicles in such physical fields, as hydroacoustic and light. As one of the main conditions of target detection in hydrosphere, it was proposed to use information-measuring and control systems of underwater vehicles to detect their own physical fields of search objects, different in character from the similar fields of the environment. The probability density distribution of signals and interference in the hydroacoustic field is investigated. It is shown that for the detection of the search object around operation, that is, the visibility of on-board measuring systems, it is necessary and sufficient to identify the presence of local heterogeneity of the hydrosphere, formed by the targets. The systems that implement this condition are proposed.

Для приведенных режимов были проведены механические испытания образцов, показавшие, что разрушение происходило по основному металлу – пермендюру. Результаты могут быть использованы для решения данной технологической задачи, а также (при проведении дополнительных исследований) для решения аналогичных проблем получения неразъемных соединений из разнородных сплавов, которые должны работать в условиях ударных знакопеременных циклических нагрузок.

The article presents the results of the development of technologies for joining a titanium alloy with a permendyur (49Co49Fe2V), which is highly relevant in the manufacture of magnetostrictive transducers for ultrasonic impact treatment of welded joints. The options for obtaining permanent joints by various methods of soldering, welding and mechanical crimping are considered. The impact nature of the work substantiates the preference for manufacturing brazed or welded magnetostrictors. The modes for flux-free soldering in vacuum with silver-containing solders, amorphous solders of the STEMET brand (1202 and 1403) and diffusion welding through the layer of copper-containing tape LMP-2 (made by pressing ultrafine powder) are given. For the given regimes, mechanical tests of the samples were carried out, which showed that the destruction occurred along the base metal - permendyur. The results can be used to solve this technological problem, as well as (with additional research) to solve similar problems of obtaining permanent joints from dissimilar alloys, which must work under conditions of shock alternating cyclic loads.
