Представлено исследование вариантов обнаружения поломки или дефекта винта беспилотной авиационной системы (квадрокоптера) с использованием методов машинного обучения. Выполнена оригинальная оценка точности известных алгоритмов с применением на практике получаемых данных с квадрокоптера в условиях его полета. Метод. Предложенный метод основан на классификации трех состояний винтов (исправные винты, один винт искусственно деформирован, один винт сломан) с использованием алгоритмов машинного обучения. Исходной информацией являются данные, получаемые с измерительной системы квадрокоптера в реальном времени: скорость, ускорение и угол поворота относительно трех осей. Для корректной работы представленного алгоритма выполнена предварительная обработка данных с разделением на временные интервалы и применением к полученным интервалам быстрого преобразования Фурье. На основе обработанных данных проведено обучение алгоритмов машинного обучения с использованием метода опорных векторов, алгоритма k-ближайших соседей, алгоритма дерева решений и многослойного персептрона. Основные результаты. Выполнено сравнение полученных значений точности предложенных методов. Показано, что применение методов машинного обучения позволяют обнаруживать и классифицировать состояния винта с точностью до 96 %. Наилучший результат достигнут с использованием алгоритма дерева решений. Практическое значение. Результаты исследования могут иметь практическое значение для систем обнаружения дефектов и поломок винтов беспилотных летательных аппаратов в реальном времени. Получена возможность прогнозирования с высокой точностью износа винта, повышать стабильность и безопасность полета.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents a study of options for detecting a failure or defect in the propeller of an unmanned aircraft system (quadcopter) using machine learning methods. An original accuracy evaluation of the known algorithms using in practice the data obtained from the quadcopter in its flight conditions is performed. The proposed method is based on the classification of three propeller states (serviceable propellers, one propeller artificially deformed, one propeller broken) using machine learning algorithms. The input information is the data obtained from the quadcopter measuring system in real time: speed, acceleration and rotation angle relative to three axes. For the correct work of the presented algorithm, data was preprocessed with division into time intervals and applying to the obtained intervals the fast Fourier transform. Based on the processed data, machine learning algorithms were trained using the reference vector method, k-nearest neighbor algorithm, decision tree algorithm, and multilayer perceptron. The obtained accuracy values of the proposed methods are compared. It is shown that the application of machine learning methods can detect and classify the propeller states with an accuracy of up to 96 %. The best result is achieved using the decision tree algorithm. The results of the study can be of practical importance for real-time systems to detect propeller defect and breakage for unmanned aerial vehicles. It is possible to predict with high accuracy the propeller wear; it is possible to improve the stability and safety of the flight.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>беспилотная авиационная система</kwd><kwd>квадрокоптер</kwd><kwd>машинное обучение</kwd><kwd>детектирование поломки винта</kwd><kwd>метод опорных векторов</kwd><kwd>дерево решений</kwd><kwd>k-ближайших соседей</kwd><kwd>многослойный персептрон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>UAS</kwd><kwd>quadcopter</kwd><kwd>machine learning</kwd><kwd>propeller failure detection</kwd><kwd>support vector method</kwd><kwd>decision tree</kwd><kwd>k-nearest neighbors</kwd><kwd>multilayer perceptron</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Зенкин А.М., Осинкин Е.А., Пачковский К.А.
