Abstract
The purpose of this report is to provide a synopsis of the data system designed to measure, record, and process High Altitude Critical Atmospheric Turbulence (HICAT) data. The HICAT Project is to measure gust velocity components in the altitude range of 40 to 70 thousand feet in several world areas. The goal is a statistical definition of the 'roughness' of the atmosphere which can be applied to design requirements for advanced aircraft structures. A Pulse Code Modulation airborne system is described. Highly accurate sensors and components, including an inertial platform, are used aboard a WU-2 test aircraft in an attempt to resolve fine scale forces, accelerations and aircraft motions in the atmospheric gust field. The magnetic tapes and other pertinent information are sent to a data processing ground station for generation of a computer-compatible tape, processing, and detailed analysis. Power spectral functions of the gust components are of major interest. Output data are correlated with meteorological and geographical data associated with the test site.
