Abstract:

Flight data from a 60 degree delta wing aircraft have been analysed using a modified Newton-Raphson parameter estimation procedure. The model equations used for the analysis were extended to account for sideslip vane errors and for lateral accelerometer position error. Lateral derivatives extracted from the data have been compared with wind tunnel measurements and theoretical estimates and areas of agreement and disagreement identified. The method has also been applied to the analysis of fin loads measured in flight and some tentative conclusions reached. The results confirm the effectiveness of the parameter identification procedure in flight test analysis and its ready applicability to a variety of related problems. Author
