COMPUTATIONAL AIRCRAFT DYNAMICS AND LOADS

An alternative approach that has the potential to advance classical me thods of flight load prediction by combining computational fluid dynam ics (CFD), structural flexibility and the interaction of flight contro l system (FCS) in a multidisciplinary analysis package is described. T he method employs the concept of system identification to characterize aircraft dynamics in the state space coordinate system and includes a n adaptive control law design methodology. An extended account of the theoretical basis for the new multidisciplinary flight manoeuvre analy sis will be presented in one of a seven-volume series on computational mechanics by Argyris and his associates to be published shortly. Howe ver, as a precursor to the complete work, a brief account of the theor etical development leading to this loads prediction methodology is inc luded in this paper.
