Analysis of T-2C High Angle of Attack Flight Test Data with Nonlinear System Identification Methodology

Abstract

This study represents one of the first thorough applications of advanced nonlinear system identification techniques to the problem of determining aircraft aerodynamic characteristics in the maximum-lift flight regime, and has produced results confirming the ability of these methods to develop realistic and useful dynamics models for flight test data and to provide a valuable guide for data acquisition system specification in future flight test programs. This study also demonstrated the value of employing wind tunnel data and theoretical (or empirical) aerodynamic analyses during the model structure determination stage in order to begin with a basic familiarity with the nature of nonlinearities to be encountered.
