Measurement And Analysis Of Low Altitude Atmospheric Turbulence Obtained Using A Specially Instrumented Gnat Aircraft

Measurement and Analysis of Low Altitude Atmospheric Turbulence Obtained Using a Specially Instrumented Gnat Aircraft

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.

Manual on the Flight of Flexible Aircraft in Turbulence

In the course of the past few years the Structures and Materials Panel of AGARD has considered a number of aspects of the turbulence problem as it affects aircraft. The present publication constitutes a review document in which is distilled the experience of specialists from amongst the aircraft manufacturing nations of NATO. It is aimed at those in design offices concerned with the problems of turbulences and resultant loads.
