A description of the general qualitative picture of the possibility of implementing the non-reactive principle of motion of an extended body in a central gravitational field is presented. In strict accordance with the laws of classical mechanics, a non-reactive principle of displacement of the mass center of an extended body in a central gravitational field is shown, based on the internal redistribution of the total kinetic moment of the body between the kinetic moments of the mass center of the body and relative to the mass center of the body. The dynamics of the Beletsky - Hirwitz gravity plane has been studied. The issues of practical implementation of the non-reactive principle of motion are considered, including from the point of view of quantum physics. It is shown that the principle of motion based on the use of the spin of low-energy elementary particles is more efficient than a photon rocket. In particular, the use of the graviton spin for the motion of bodies is a billion times more efficient than the use of the graviton for jet motion and makes it possible to achieve body acceleration of more than 6,600 m/s<sup>2</sup> without overload. The results obtained can be used in experiments to search for elementary particles with low energy, to explain cosmic phenomena and to develop transport objects based on new physical principles.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Изложены теоретические исследования механики космического полета протяженного твердого тела типа гантель. Представлено описание общей качественной картины возможности реализации нереактивного принципа движения протяженного тела в центральном гравитационном поле. В строгом соответствии законам классической механики показан нереактивный принцип перемещения центра масс протяженного тела в центральном гравитационном поле, основанный на внутреннем перераспределении полного кинетического момента тела между кинетическими моментами центра масс тела и относительно центра масс тела. Изучена динамика гравилета Белецкого - Гирвица. Рассмотрены вопросы практической реализации нереактивного принципа движения, в том числе с точки зрения квантовой физики. Показано, что принцип движения, основанный на использовании спина низкоэнергетических элементарных частиц, эффективнее фотонной ракеты. В частности, применение спина гравитона для движения тел в миллиард раз эффективнее применения гравитона для реактивного движения и позволяет достигнуть ускорения телом более 6600 м/с<sup>2</sup> без перегрузки. Полученные результаты могут быть использованы в экспериментах для поиска элементарных частиц с низкой энергией, объяснения космических феноменов и разработки транспортных объектов на новых физических принципах.</p></trans-abstract><kwd-group xml:lang="en"><kwd>non-reactive propulsion</kwd><kwd>space flight</kwd><kwd>gravitational flight</kwd><kwd>gravitation</kwd><kwd>motion without overload</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нереактивное движение</kwd><kwd>космический полет</kwd><kwd>гравилет</kwd><kwd>гравитация</kwd><kwd>движение без перегрузки</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">Dorfman YaG.
