Abstract
Within the general theory of relativity the Bianchi type VIII cosmological models with rotation and expansion have been built. 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.
