This product is a basic experimental platform used to study the basic laws of low-speed flow in aerodynamics, verify and develop relevant theories. The wind tunnel is mainly composed of a tunnel body (including a muffler), a drive system, and a basic control system. The experimental section can install various wing shapes, aircraft, and other object models to study the interaction between air and the model, including lift, drag, pitch moment, pressure distribution, etc; An additional 32 pressure testing units, smoke generators, and three component balance modules are available for conducting multiple theoretical verifications and experimental studies related to aerodynamics. Some modules support custom extensions, experimental design, and expansion.
