System Identification of the Longitudinal Motion of the Dfvlr Hfb 320 Research Aircraft with Particular Consideration of Control Surface Effectiveness

摘要

Analysis of the longitudinal motion of the DFVLR HFB-320 research aircraft by means of a maximum likelihood method is described. The control surface effectiveness of separately or simultaneously deflected DLC flaps and spoilers was determined. The flight test technique, and the influence of different mathematical models on the results obtained, are illustrated and discussed.
