Description:
Air passes into the wind tunnel through a honeycomb flow straightener and a grille. It then passes into an aerodynamically designed eff user (cone) that accelerates the air in a linear manner before it moves through the working section. Finally, it passes through a diff user, then into the variable speed axial fan. The grille protects the fan from damage by loose objects. The air leaves the fan, passes through a silencer unit and then back out to atmosphere. The speed of the axial fan (and therefore the air velocity in the working section) is controlled by an electronic drive control in the separate On/Off unit mounted on the tunnel’s associated instrument frame along with other ancillaries. Working Section The working section is of a square section with an acrylic roof and fl oor. The sides are full length acrylic panels and can be removed. The whole unit is supported in an aluminium framework. Each side panel has a holder to support wind tunnel models. On the top of the working section are two Pitot devices and a wall tapping to measure the static pressure upstream and downstream of the working section.
