| Summary: | The article presents the results of numerical studies of aerodynamic characteristics of isolated three-bladed tail rotor, and X-shaped tail rotor at "vortex ring". Calculations of aerodynamic characteristics of rotors are based on nonlinear blade vortex model developed at the Department of "The helicopter design" MAI. Considered hover and blasting at positive angles of attack αH, including the area of "vortex ring". Built "vortex ring" area in the coordinates of the horizontal Vx and vertical velocity Vy of airflow at different angles of attack of the rotor by condition drop rotor thrust against hover thrust at fixed angles of rotor collective pitch. |
