After refreshing your theory and equipment knowledge, Please note the experiment availability as in table below. This experiment is AVAILABLE ON SAT/SUN/MON/TUE.
- Go to RT tab and click "Click here to start experiment" button in the variable panel.
- Click the "Start" button
- Click the"Pitot Calibration" button
- Wait till the "Pitot position" in the station status to reach 40mm, only then the "Angle calibration" button will be activated.
- Click the "Angle Calibraion" button
- The "Set air velocity" slider is activated when "Angle of attack" in station status reaches zero degree.
- Start the tunnel by setting a velocity of 15m/s on the "Set air velocity" slider.
- Set an angle of attack of 2 degree using the "Angle control" slider
- Observe the loads from the strain balance for Lift and Drag.
- The process can be repeated only after ploting the graph (which is after a few seconds). Untill then the "Angle control" slider will be deactivated.
- Repeat steps 8 to 10 for 4 deg, 6 deg, 8 deg.
- Be aware of stall onset. Don't change the angle higher than advised.
- Verify the CL and CD vs. alpha curves with textbook plots. (Rae and Pope, Low Speed Wind Tunnel Testing).
- Click the "Stop" button to stop the experiment.
