Aircraft mathematic model parameters identification technique based on the follow-up system synthesis

Aviation technics and technology


Nikitin A. I.


The given paper considers aerodynamic coefficient identification technique suggested by author. In fact, solves inverse dynamic problem: with aid of angel velocity and acceleration records restores forces and moments, which were cause of this velocity and acceleration. Paper describes algorithms and equations for restoring aircraft longitudinal and lateral motion parameters for aircraft without dampers. Transient process plots until and after identification shows suggested technique efficiency.
