A wind tunnel is the standard experimental platform for researching aerodynamic flow. The model under investigation remains at rest while the flow medium is set in motion, producing the necessary flow around it.
In an exposed wind tunnel, the aerodynamic properties of several models are exhibited and measured. For this, air is drawn in from the atmosphere and accelerated. Air circulates around a model, such as an aerofoil, in a measurement section. The air is slowed down in a diffuser and then pumped back into the open by a fan.
The well planned nozzle contour and a flow straightener ensure a homogeneous velocity distribution with little turbulence in the closed measuring region. The flow cross section of the measurement component is square. Its defining characteristics include an integrated axial fan with a guiding vane, variable-speed drive, and energy-efficient operating at high efficiency. Air speeds of up to 28 m/s can be reached in this open wind tunnel. The trainer has an electrical two-component force sensor.Recognisable and graphically portrayed are lift and drag. The air velocity in the measurement region is displayed by the inclined tube manometer. To measure the pressure curves in drag bodies, tube manometers are indicated.
A variety of studies are made possible by a
variety of accessories, including those that measure lift, analyse boundary
layers, measure pressure distributions, and visualise streamlines. The thorough
course materials provide an overview of the principles and a step-by-step
walkthrough of the experiments.
