OPEN WIND TUNNEL APPARATUS: PSAW-509TL
Technical Description
A wind tunnel is
the classic experiment system for aerodynamic flow experiments. The model being
studied remains at rest while the flow medium is set in motion, and thus the
desired flow around the model is generated.
Open wind tunnel
used to demonstrate and measure the aerodynamic properties of various models. For
this purpose, air is drawn in from the environment and accelerated. The air
flows around a model, such as an aerofoil, in a measuring section. The air is
then decelerated in a diffuser and pumped back into the open by a fan.
The carefully
designed nozzle contour and a flow straightened ensure a uniform velocity
distribution with little turbulence in the closed measuring section. The flow
cross section of the measuring section is square. The built-in axial fan with
guide vane and a variable-speed drive is characterized by an energy-efficient
operation at high efficiency. Air velocities of up to 28m/s can be reached in
this open wind tunnel. The trainer is equipped with an electronic two-component
force sensor. Lift and drag are detected and displayed digitally. The air
velocity in the measuring section is displayed on the inclined tube manometer.
The tube manometers are recommended for measuring the pressure curves in drag
bodies.
Extensive
accessories allow a variety of experiments, for example lift measurements,
pressure distributions, boundary layer analysis or visualization of
streamlines. The well-structured instructional material sets out the
fundamentals and provides a step-by-step guide through the experiments.
