This work sufficiently appends and extends experimental investigation of flow structure downstream of the triblade turbine model, which was started in 2011. Shadow zones from blades were removed and a measuring zone was increased as a result of changing in optical system of PIV. These changes made possible to carry out measurements in much more far zone downstream the rotor model. As a result new features of flow were found out in near and far wake downstream the turbine. The estimation of turbine work efficiency on different work regimes was carried out due to tensometric measurements of rotor force characteristics. This data corresponds to assumptions and hypothesis of classical theories of rotors and to a form for the optimum blades designed by the BEM method. Keywords:
