Wing-Lift Demonstrator
★Exhibit Content: Demonstration of Wing Lift Principle ★Interaction: Electromechanical Interaction ★Operation: Press the power button to start the wind tunnel; rotate the wind speed adjustment knob to adjust the wind speed; observe the flight status of the aircraft model and the effect of airflow on the model's state. ★Exhibit Description: The exhibit consists of a cabinet display stand, wind tunnel chamber, observation window, EVA aircraft model, operation buttons, electrical control box, and fan system. It is a recommended exhibit from KexMall. Visitors press the power button to start the fan, adjust the airflow speed inside the wind tunnel via the knob, and intuitively see the aircraft model lift in response to airflow changes through the transparent observation window, directly experiencing the process of wing lift generation and understanding the fluid dynamics behind flight. ★Scientific Principle: The wing shape is convex on top and flat on the bottom. When airflow passes over the wing surface, the air speed on the upper surface is faster than on the lower surface; according to Bernoulli's theorem, the faster the fluid flow, the lower the pressure, creating a pressure difference between the upper and lower surfaces of the wing. This pressure difference is the wing lift. When the lift exceeds the model's weight, the model is lifted, thereby revealing the core principle of how aircraft can take off.
