Scaling Method of the Rotating Blade of a Wind Turbine for a Rime Ice Wind Tunnel Test
Energies, 2019 In order to research the law of rime ice accretion on different scaling blades surface, a new rime ice scaling method was proposed in this research. According to previous research, there are three kinds of ice types on blade surfaces: rime ice, glaze ice

Photogrammetry applied to wind-tunnel testing [PDF]
AIAA Journal, 2000 In image-based measurements, quantitative image data must be mapped to three-dimensional object space. Analytical photogrammetric methods, which may be used to accomplish this task, are discussed from the viewpoint of experimental fluid dynamicists.

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,

Spray drift characteristics test of unmanned aerial vehicle spray unit under wind tunnel conditions
International Journal of Agricultural and Biological Engineering, 2020 Since the 2010s, unmanned aerial vehicle (UAV) sprayer was applied more and more widely for low-volume aerial pesticides spraying operations in China. However, droplets from the UAV sprayer have a higher drift risk due to more fine droplets sprayed and a
