Egorova E. U., Levitin . M., Ovcharenko V. N.


In the article the identification aerodynamic characteristics of the angular motion is described in the time domain from parameter’s recording of longitudinal maneuvers. The algorithm of adaptive identification is used, witch permits estimate elements of the pitching moment coefficient. As element’s initial approximation the aerodynamic database values are chosen which obtained from the results of wind tunnel tests.
