Subsonic Wind Tunnel 305 mm
Model Number: AF1300S
A compact subsonic wind tunnel starter set for hands-on aerodynamics experiments.
Overview
A starter set consisting of the Subsonic Wind Tunnel 305 mm (AF1300), Basic Lift and Drag Balance (AF1300z) and a set of Three-Dimensional Drag Models (AF1300j).
Air enters the tunnel through an aerodynamically designed effuser (cone) that accelerates the air linearly. It then enters the working section and passes through a grill before moving through a diffuser and then to a variable-speed axial fan. The grill protects the fan from damage by loose objects. The air leaves the fan, passes through a silencer unit and then back out to atmosphere.
A separate control and instrumentation unit controls the speed of the axial fan (and the air velocity in the working section). The control and instrumentation unit also includes manometers and electrical outlets to supply electrical power to other optional instruments. A metal frame supports the wind tunnel. The frame includes lockable castors for convenient mobility.
The working section of the tunnel is a square section with a clear roof, sides and floor. The sides are removable. The floor and each side panel has a special position to support the optional wind tunnel models.
