This product is a basic experimental platform used to study the basic flight characteristics of aircraft at low speeds and verify relevant theories. The wind tunnel mainly consists of a tunnel body (including a muffler), a model display section, a drive system, and a measurement and control system. The control system can adjust the tail angle and wind speed to study the interaction between air and the model. Through intuitive control, it simulates takeoff, horizontal flight, landing, stall, center of gravity displacement, pitch oscillation, heave oscillation, etc; By combining variable frequency speed regulation, resistance sensors, and Taft wire, experimental research and theoretical verification can be carried out on the drawing of lift curves for various flight postures of aircraft models.
