It’s known that dark energy can be simulated by different kinds of energy-stress tensor, therefore the sources of gravitation in present article are an anisotropic fluid, with a pressure component satisfying to Chaplygin gas equation of state and a perfect fluid in the first case and an anisotropic fluid, Chaplygin gas and cosmological constant in the second case. It has been proved that the model, when expanding from Plank scale to the modern size gives satisfactory value of the angular velocity value. The found solutions can be used for effects taking place nowadays and at the inflationary stage.</p></abstract><trans-abstract xml:lang="ru"><p>В рамках общей теории относительности построены соответствующие космологические модели с расширением и вращением с метрикой типа VIII по Бьянки. Известно, что тёмная энергия может моделироваться различными видами тензора энергии-импульса, поэтому в данной работе источниками гравитации являются в первом случае анизотропная жидкость, одна из компонент давления которой имеет уравнение состояния газа Чаплыгина, и идеальная жидкость, а во втором случае - анизотропная жидкость, газ Чаплыгина и космологический член. Показано, что модель, при рассмотрении расширения от планковских масштабов до современного размера наблюдаемой Вселенной, даёт удовлетворительную величину порядка угловой скорости её вращения. Полученные решения могут быть применены к изучениям эффектов, имеющих место в современную эпоху, а также во время инфляционной стадии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cosmological expansion</kwd><kwd>Chaplygin gas</kwd><kwd>anisotropy of the Universe</kwd><kwd>accelerated expansion</kwd><kwd>type VIII Bianchi metric</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>космологическое расширение</kwd><kwd>газ Чаплыгина</kwd><kwd>анизотропия Вселенной</kwd><kwd>ускоренное расширение</kwd><kwd>метрика VIII типа Бьянки</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">K.
