Abstract:

Detailed measurements of atmospheric turbulence made by a specially instrumented Gnat aircraft at altitudes below one thousand feet over a variety of terrains are described. A programme of flying yielded about 400 runs for which time histories of the three components of turbulence are available. These runs are analysed to give parameters which summarize the statistical characteristics of the turbulence encountered. A very strong relationship between two parameters from the Statistical Discrete Gust analysis technique and one from the Power Spectral Density technique is identified.
