Учитывая, что наиболее широко применяемым классом движителей являются гребные винты, рассматривается одна из возможных перспективных схем петлевидного гребного винта, позволяющая значительно улучшить гидродинамические, акустические, вибрационные и кавитационные характеристики винта. В работе используется численное моделирование, на основе которого рассчитаны кривые действия гребных винтов для выявления влияния геометрических параметров петлевидного гребного винта на его рабочий процесс. Проведено сравнение различных вариантов петлевидных гребных винтов и выявлено наиболее перспективное сочетание геометрических параметров. Задачи повышения эффективности гребных винтов решаются параметрической оптимизацией геометрии нетрадиционных схемных решений гребных винтов.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the work is to find ways to improve the characteristics of water propellers. Taking into account that propellers are the most widely used, considered one of the possible promising schemes a loop-shaped propeller, which makes it possible to significantly improve the hydrodynamic, acoustic, vibration and cavitation characteristics of the propeller. The work uses numerical simulation, on the basis of which the propeller action curves are calculated to identify the influence of geometric parameters of the loop propeller on its working process. A comparison of various variants of loop propellers is carried out, identified the most perspective combination of geometric parameters. The requirements for the propulsors of perspective ships set the task of increasing the efficiency of propellers, which are solved by parametric optimization of the geometry of non-traditional schematic solutions of propellers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гребные винты</kwd><kwd>петлевидные винты</kwd><kwd>численное моделирование</kwd><kwd>кривые действия</kwd><kwd>перспективное судостроение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>propellers</kwd><kwd>loop propellers</kwd><kwd>numerical simulation</kwd><kwd>propeller action curves</kwd><kwd>perspective ships</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">Месропян А.
