Abstract:
Based on the GB/T24559 marine propeller anemometer test methods and test points, the propeller anemometer was tested in the lowspeed wind tunnel. According to the JJF1059.12012 measurement uncertainty evaluation and expression requirements, seven calibration points of wind speed were tested repeatedly, and the range method was used to evaluate the type A uncertainty. The sources of type B uncertainty in the testing process are analyzed and the type B uncertainty is evaluated. The results show that it is feasible to calibrate the propeller anemometer in the WZ860070E wind tunnel. At the same time, each test point above 2 m/s can meet the three times of the quantitative transmission relationship.
