Description
This wind tunnel is an open circuit downstream fan type designed for studying subsonic aerodynamics.
Air enters the tunnel via the entrance flare. A flow straightener, three wire mesh screens, and a high contraction ratio section ensure uniform velocity across the transparent test section. Downstream of the working section is a low angle diffuser which terminates at the tunnel fan. The diffuser and contraction sections have a high quality internal finish to minimize the boundary layer effects. Fan impeller blades are of an aerofoil design cast aluminum to ensure maximum aerodynamic efficiency and minimum turbulence. Fan speed is adjusted by inverter.
Four equally spaced static pressure taps are connected to a manifold to minimize effects from a model. Air speed is indicated by an inclined manometer and a calibration graph. Models are mounted on two supports with indicators for measurement of drag and lift. The model holder can be rotated to allow quick changes on the angle of incidence. Angle is indicated on an angular scale at the base of the holder.
Test Section: 300 x 300 x 600mm. Securely mounted on a mobile bench.
Many options and accessories are available.
