This paper examines the use of a pitot-static tube array (PSA) to estimatehorizontal wind velocity in all directions. This method uses the readings fromthe PSA as inputs. No flight tests have been done, but this method couldpotentially be used to estimate wind velocity from small UAVs. To do this, UAVground speed and attitude must be available as inputs. Wind tunnel data of thePSA was used to create an algorithm that estimates wind velocity even when thewind is not parallel with any of the pitot-static tubes. This paper discusesthe wind tunnel data, the algorithm, and the application for small UAVs.
