Abstract:

The report describes the processing and analysis phases of the Medium Altitude Critical Atmospheric Turbulence MEDCAT Project. The primary objective of this project was to collect true gust velocity in the 20,000 to 40,000 foot altitude regime to be used to establish, validate, andor modify future aerospace vehicle design criteria. The data, collected by the Air Force from seven bases in the Continental United States consists of 278 flights performed in the regions of the MEDCAT altitude band predicted by a meteorologist as being most likely to contain clear air turbulence. Two trubulence-instrumented aircraft - an F-106A, and an F-100F - were used to collect the data. Of the 40 hours judged as being in turbulence 81 percent was characterized as being of less intensity than 1.5 ftsec rms true gust velocity. Author
