【 摘 要 】

This paper discusses the problems of aerodynamic coefficients identification from flight test data. The principal stages of identification procedure are considered, the more sophisticated stages such as data compatibility check and parameter estimation from flight data are discussed in details. The paper also presents the examples of flight test data processing, which confirm the opportunities for on-board measurement systematic error detection and wind tunnel aerodynamic parameter values correction.
