MP 330D SUBSONIC WIND TUNNEL, Downstream Fan
The wind tunnel is an open circuit down stream fan type designed for studying the subsonic aerodynamics. It is to be used with optional accessories and models below.
The air enters the tunnel via an 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. The fan impeller blades are of an aerofoil design cast aluminum to ensure maximum aerodynamic efficiency and minimum turbulence. Fan speed is adjustable by an 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 components balance support with digital display for measurement of drag and lift. Model holder can be rotated to allow quick change on the angle of incidence. This angle is indicated on an angular scale.
The tunnel is mounted on a stainless steel table on wheels.
Instruction manual is also included.
