Lifting Rotors

Testing of rotor large-scale models with diameter up to 5m over the speed range from 0 to 430 km/h in the T-104 wind tunnel with test section of 7m in diameter.
Testing of large-scale rotorcraft models with rotor diameter about 4-5m in the T-104 wind tunnel.
Study of aerodynamic and aeroelastic characteristics of full-scale rotor with diameter up to 17m in the T-101 wind tunnel with 14x24m test section.
Aerodynamic characteristics of tilt rotors and wind-wheels are determined in the T-101 and T-104 wind-tunnel.
