The Effect of Constant versus Oscillatory Rates on Dynamic Stability Derivatives.

Abstract

The purpose of this thesis was to determine whether or not there are phenomenological differences between dynamic derivations calculated from F-15A rotary balance data and data from other sources. To make this determination, two additional data sets were obtained: (1) the F-15A design phase stability derivative data, and (2) the F-15A production phase stability derivative data. The lateral dynamic derivatives were then compared through derivatives of the lateral moments with respect to the rotation rate about the velocity vector (wind vector). The conclusion of the project was that differences exist between the data sets, but that the dominant characteristic were the same for all of the data sets; the differences in the data were not indicative of basic (phenomenological) the differences in the data itself. Therefore, the contention that oscillatory rates affect determination of the dynamic derivations was not substantiated by this study. (Author)
