| Popis: | The paper considers the features of the innovative design and gas dynamics of the flow in the flow path of the cutting-separating turbine unit of the flax combine. On the basis of the combine tests, the possibility of using a turbine unit to ensure a stable movement of the working mixture in the pneumatic transport system of the combine was considered. To provide the necessary pressure characteristics, a method for designing a flow path is proposed on the basis of the hypothesis of the analogy of the action on the flow of a set of cutting sets with a centrifugal compressor blade.
