The wind tunnel is an open circuit upstream fan type, designed for studying the subsonic aerodynamics. It is to be used with optional accessories and models below.

A dual an axial flow fans delivers air through a diffuser, flow straightener, three wire mesh screens and a high contraction ratio section to ensure uniform velocity across the transparent test section. The diffuser and contraction sections have a high quality internal finish to minimize the boundary effects. The fan impeller blades are of an aerofoil design cast aluminum to ensure maximum aerodynamic efficiency and minimum turbulence. The fan speed is adjustable by an inverter. 

Four equally spaced static pressure taps are connected to a manifold to minimize effects from a model and air speed is indicated by an inclined manometer and a calibration graph. Models are mounted on two components load cell 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 wind tunnel is mounted on a steel table on wheels.
