Wind Tunnel Test Technique for Measuring Unsteady Loads on Rotor Blade Surfaces |
| |
| Abstract: | In order to measure and analyze the unsteady loads on the rotor blade surface, a complete technical scheme of
wind tunnel test is proposed. A multi-channel rotary data acquisition device is developed based on the design scheme of
embedded sensors, and the synchronous sampling method of external clock and external trigger is used to realize the
function of repeated sampling at equal angle intervals during the movement of the rotor, thus solving the synchronization
problem between the azimuth angle of the rotor and the sample data. The wind tunnel test results verify the feasibility of the
test technology. |
