Description:
The wind tunnel that the turbine is mounted in has a bell mouth and honeycomb for flow settling on the inlet. Speed is measured by an anemometer that is stowed away when not in operation so the flow is not disturbed. The turbine can be viewed from both sides of the tunnel through a transparent window and a sliding door with an interlock. The turbine features motorised blade pitching and digital read-back so down time during experiments is reduced. Attached to the base of the turbine is the yawing mechanism and the setting handle. The turbine is compatible with custom-designed 3D-printed blades built upon the hub CAD file provided . A removable silencer is attached to the rear of the wind tunnel to reduce noise pollution. The silencer can be stowed beneath the apparatus to reduce space when it is stored. The built-in safety features include an interlock on the door so that it can’t be opened while the turbine is turning and a smart shut down system that turns off the wind tunnel fan in the event that over current or over speed is detected.
