Tangential developable surfaces are ruled surfaces of zero Gaussian curvature with cuspidal edges. They give great opportunities to architects and engineers for realization of their creative projects. Both the theoretical researches in the area of geometry of torses and strength analysis of shells and the influence of these researches on the application of torses in practice are shown. A presented research demonstrated that torses found the application in shipbuilding, aircraft construction, mechanical engineering, in architecture and building, engineering equipment and communications, in road building, in anti-erosive banks, topography, and cartography, clothing articles of light industry, in sculptural forms, and in modelling with developable surfaces. It was confirmed by the references on great number of published works on the subject, real examples from practice, and by handing in 14 illustrations of real objects.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Класс развертывающихся поверхностей включает в себя цилиндрические, конические и торсовые поверхности. Торсовые поверхности - это линейчатые поверхности нулевой гауссовой кривизны с ребром возврата. Они дают большой простор архитекторам и инженерам для реализации творческих планов. Представлены как теоретические исследования в области геометрии и прочности торсов, так и образцы применения торсов в реальных структурах. Проведенный анализ источников показал, что торсы нашли применение в судо-, самолето- и машиностроении, в архитектуре и строительстве, в формах инженерного оборудования, в дорожном строительстве, при строительстве противоэрозионных валов, в топографии и картографии, в текстильной промышленности, в скульптурных формах и при аппроксимации сложных поверхностей. Это подтверждается ссылками на большое число опубликованных работ по теме и реальными примерами возведенных сооружений и объектов. Приведено 14 иллюстраций соответствующих структур.</p></trans-abstract><kwd-group xml:lang="en"><kwd>tangential developable surface</kwd><kwd>shipbuilding</kwd><kwd>mechanical engineering</kwd><kwd>architecture</kwd><kwd>building</kwd><kwd>engineering equipment</kwd><kwd>road building</kwd><kwd>anti-erosive banks</kwd><kwd>topography</kwd><kwd>clothing articles</kwd><kwd>light industry</kwd><kwd>sculptural forms</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>торсовая поверхность</kwd><kwd>судостроение</kwd><kwd>машиностроение</kwd><kwd>архитектура пространственных систем</kwd><kwd>инженерное оборудование</kwd><kwd>дорожное строительство</kwd><kwd>антиэрозионный вал</kwd><kwd>топография</kwd><kwd>изделия легкой промышленности</kwd><kwd>скульптурная форма</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Krivoshapko S.N.
