Abstract

We present results of system identification of a twin engine fixed wing aircraft with structural damage. Flight test data recorded as the aircraft performs a specifically selected system identification maneuver with 25% left wing missing is used. This data has been used to estimate a complete six degree of freedom aircraft linear model with asymmetric stability derivatives using the recursive Fourier Transform Regression method in frequency domain and the traditional least squares method in time domain. This paper shows the feasibility of using the frequency domain Fourier Transform Regression method for real-time parameter identification of damaged aircraft.
