The Effect of Horizontal Wind Speed on the Angle of Deflection from the Vertical of a Hanging Board

Influence of horizontal wind speed on the deflection angle of the lifting plate in the vertical direction Objective: To plan an experiment to study how the horizontal wind speed affects the vertical deflection angle of the hanger board.

Wind shear is a sudden tear or shear effect occurring at the edge of the area that changes dramatically along the wind speed or wind direction. It can exist horizontally or vertically, and creates stirring motion and therefore turbulence. Under certain conditions, the wind direction will change up to 180 degrees and the measurement speed will change up to 80 knots. The impact of wind shear on aircraft performance arises from the fact that the wind can change faster than the acceleration or deceleration of the mass of the aircraft. Violent wind shears can degrade the performance of aircraft beyond their compensation ability, especially during the important landing and takeoff phases of the flight.

Wind shear occurs both horizontally and vertically. Vertical shear is most common near the ground and can cause serious damage to the aircraft during takeoff and landing. Aircraft are flying at a slower and relatively more resistant configuration. The height of recovery and stall is small, the maneuvering margin is the lowest. An aircraft experiencing the Wind shear phenomenon may experience a significant airspeed loss due to the sudden change in relative air flow as the aircraft jumps to the new moving air mass. A sudden drop in the airspeed may cause a stall and it is dangerous if the aircraft is only a few hundred feet away from the ground and very fragile.
