Abstract:

Fighter load spectra derivation using evaluation and validation flight test data is a new method. Rationality, possibility, technical crux and methodology are simply stated. The principle and method for making load spectra flights are given. Notices in collecting data are listed. The methods used in pre treating and treating data are presented. Finally, deriving the load spectrum using evaluation and validation flight test data of a fighter is given as an example to explain the process and the method.

Key words: fighter, load spectrum, flight test
