A Limited Evaluation of the Have Derivatives Process to Reduce Aircraft Stability Derivative Estimate Errors Caused by Turbulence (Have Derivatives)

Abstract

This report presents the results of a limited evaluation of the HAVE DERIVATIVES data reduction process in reducing aircraft stability derivative estimate errors caused by turbulence. The evaluation consisted of 11 sorties totaling 15.2 flight hours. The sorties were flown at the Air Force Flight Test Center, Edwards AFB, California, in a production-representative Block 15 F-16B aircraft. The three specific objectives for this project were to establish a basis data set of results against which to compare the results of the subsequent tests; compare stability derivative estimate results found using the HAVE DERIVATIVES process with Personal Computer Parameter Identification (PCPID), on calm air data, to the basis data set results established in objective 1; and compare stability derivative estimate results found using PCPID alone and the HAVE DERIVATIVES process with PCPID, on turbulent air data, to the basis data set results established in objective 1, and to each other.
