Evaluation of Aerodynamic Characteristics in Oscillatory Coning Using CFD Methods [PDF]
Proceedings of the 9th European Conference for Aerospace Sciences,
2022, 2022 The wind tunnel rotary-balance testing is widely used in aircraft dynamics to characterise aerodynamics at moderate and high angles of attack during stall and spin regimes. In such experiments an aircraft test model is rotated along the wind-tunnel free-stream velocity vector allowing the measurement of aerodynamic characteristics in steady rotational ...

A New Method for Adjusting Setting Angle of Rotor Blade for Axial Fan in Wind Tunnel
Xibei Gongye Daxue Xuebao, 2019 Combining the fan aerodynamic efficiency with the wind tunnel pressure loss coefficient, a new equation which points out the inherent relationship of the fan blade setting angle, fan rotating speed and gas flow rate in wind tunnel circuit is derived ...

Wind tunnel testing of a wind turbine in complex terrain
Journal of Physics: Conference Series, 2020 AbstractThe paper describes the development of a scaled model of complex terrain, suitable for terrain-wind turbine interaction wind tunnel studies, taking into account flow similarity criteria. The size and the geometry of the experimental model of the complex terrain were refined using results of CFD simulations in order to achieve the best possible ...

Testing of calibration models in order to certify the overall reliability of the trisonic blowdown wind tunnel of VTI [PDF]
FME Transactions, 2010 It is strongly recommended that wind tunnel calibrations become a regular part of the operational cycle for any wind tunnel. They facilitate tunnel-totunnel data comparisons. Standard calibration model, representing a generic winged missile configuration,

Contemporary frame of measurement and assessment of wind-tunnel flow quality in a low-speed facility [PDF]
FME Transactions, 2018 The requirements for the accuracy of measurements in a wind tunnel test become more and more severe while the complexity of the test increases. In an environment of reduced time available for wind tunnel test and increasing test costs, it is important ...
