      <abstract xml:lang="ru">
        <p>При исследовании некоторых задач обтекания тел сверхзвуковым пото­ком газа систему уравнений гидромеханики удобнее записывать не в декар­товых, а в естественных координатах. Аналогичные координаты были ис­пользованы при решении задач обтекания плоских и осесимметричных тел гиперзвуковым потоком газа методом «пограничного слоя».</p>

        <p>In the study of some problems of streamline bodies with supersonic gas flow, it is more convenient to write down the system of hydromechanics equations in natural coordinates rather than in Cartesian coordinates. Similar coordinates were used in solving problems of the flow of flat and axisymmetric bodies with hypersonic gas flow by the “boundary layer” method.</p>
