Application of the Estimation-Before-Modeling (EBM) System Identification Method to the High Angle of Attack/Sideslip Flight of the T-2C jet Trainer Aircraft. Volume 1. Executive Summary

Abstract

This report (Volume I) summarizes the development and application of the 'Estimation-Before-Modeling (EBM) method for aircraft parameter identification in the non-linear flight regime. The method utilizes a 'Two-step approach wherein model independent states, forces and moments are first estimated and then state and control dependent model parametes are obtained using a Stepwise Multiple Linear Regression (SLMR) approach. In the second step (SLMR) the angle of attack and sideslip and control input space for all available flight data is divided into small subspaces and force and moment coefficients are modeled within each subspace. The method is applied to both simulated and actual flight data for a T-2C jet trainer aircraft in the stall and post-stall flight regimes. Volumes II and III of this report present detailed description of the EBM method and its application.
