Abstract
This is a report on the calibration tests and the determination of the response characteristics of a thrust anemometer designed to measure the three-dimensional instantaneous wind vector. Static tests determined the instrument calibration constants and checked the linearity of the system. Dynamic tests performed in a wind tunnel established that the ‘V 2’ drag law applies to the sensing system. The wind-tunnel tests also determined the range of angles for which the anemometer was capable of resolving the vector wind. Finally, the amplitude and phase frequency response characteristics were measured. It was found that knowledge of the latter was important in studying turbulence spectra and cross spectra. Some preliminary results from a recent field program are presented which document the need for correcting the amplitude and phase responses.
