SR-AHM170 Open wind Tunnel Didactic Equipment Fluid Mechanics Experiment Equipment
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.
SR-AHM170 is an “Eiffel” type 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 straightener 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 outlet guide vane system and a variable-speed drive is characterised 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 SR-HM 170.50 or the electronic pressure measurement HM 170.55 are recommended for measuring the pressure distribution on bodies.
By using the system for data acquisition SR-HM 170.60, the measured values for velocity, forces, moment, displacement/angle, and differential pressure can be transferred to a PC where they can be analysed with the software. Our price didn’t contain PC.
Extensive accessories allow a variety of experiments, for example lift measurements, pressure distributions, boundary layer analysis or visualisation of streamlines.
