Abstract: To improve the safety of rotorcraft operation on ships and in
urban areas, wind turbulence statistics are needed over large areas under
various conditions. This paper describes progress towards a routine capability
to make such measurements using Spatial Correlation Velocimetry. Previous
applications in several flowfields are summarized and used to describe the
variations and technical features of the method. Applications in 3 large-area
flows are demonstrated, and a quantitative verification against single-probe
measurements is shown for wind speeds of 10 to 57 fps. The computation of
turbulence statistics from such data is demonstrated. Application to the
full-scale ship environment is discussed.
