PART 2 Output power in relation to form of wings While wind energy units were developed further, different forms came into use for the wings of the converter. This experiment is used to determine the influence of the form of the wings on the operating behaviour. Objective: To determine the influence of the form of the wings on the operating behaviour of the wind energy converter. Procedure: 5. Set up the experiment according to figure 2. Use the energy converter as indicated in the diagram. 6. Ensure the range selector switch of the voltmeter is set to position "DCV 20V", the amperemeter to position "DCA 200 mA". For the load, the resistance in load 2 should be set to 50 2. 7. Mount two straight wings with a certain tilt angle, eg. 60⁰. 8. Set a wind speed at the potentiometer using the potentiometer of the blower, such as 8m/s (use diagram from part 1). 9. Measure the voltage and the current of the wind generator and calculate the power 10. Conduct the same measurement with the curved wings. The curve should be in line with the symbols printed on the angle collar of the protection cover ("normal"). 11. Repeat the measurement with one of the curved wings turned 180". i.e. the curve being opposite the symbols ("opposite") 12. Record the measurements in table.
