Abstract
The problem of comparing estimates of aerodynamic coefficients calculated from flight data with similar coefficients from the aerodynamic characteristics bank is investigated. A method for calculating optimal estimates of coefficients closest to the purge data is proposed, and its properties are established. The method has been tested on short-range aircraft flight data in longitudinal motion. A good mutual correspondence of flight and purge coefficients is shown.
