“…So the sidewind-induced velocity could be considered to be the same during one second. According to the momentum conservation law and the energy conservation law, there are formulas where the air density is obtained as r = 1:29kg=m 3 . If the UAV has acquired the lateral velocity v 0 lat , the wind speed v w could be figured out.…”

“…In the period of 1960s and 1970s, people became aware of the terrible power of the nature acting on the aircrafts and began to study it. [1][2][3] Researchers in that period found the winds resulting in aerial accidents could mainly be divided into following categories: downburst, 4 turbulent wind, 5 wind shear 6 and the wake vortex, 7 and some actions were implemented to cope with these severe meteorological environments. Professor Fujita, a Japanese scientist, took the lead in the mid-1970s in reasonably and clearly summarizing the meaning of microdownburst, after that Ivan and Woodfield realized their simulation.…”

Attitude, speed, and position of unmanned aerial vehicles are susceptible to wind disturbance. The types, characteristics, and mathematical models of the wind, which have great influence on unmanned aerial vehicle in the low-altitude environment, are summarized, including the constant wind, turbulent flow, many kinds of wind shear, and the propeller vortex. Combined with the mathematical model of the unmanned aerial vehicle, the mechanism of unmanned aerial vehicle movement in the wind field is illustrated from three different kinds of viewpoints including velocity viewpoint, force viewpoint, and energy viewpoint. Some simulation tests have been implemented to show the effects of different kinds of wind on unmanned aerial vehicle’s path and flight states. Finally, some proposals are presented to tell reader in which condition, which wind model should be added to simulation, and how to enhance the stability of unmanned aerial vehicle for different kinds of wind fields.
