Abstract�� The approach and specialties of loading spectra development using maneuvers simulation technique for new-design aircraft were introduced in brief. Onthe above basis, the approach and key-points of developing stress/pressure spectrum for integral tank, gusts and sideslip spectrum for vertical tail were presented in detail. One key step of developing stress/pressure spectrum for integral tank is to calculate the pressure of the tank in all loading cases, and the G-A-G cycle should be taken into account for the analysis spectrum of the tank. The loading spectrum of the vertical tail is obtained by not only the simulation of maneuvers but also some statistical measurements.
Keywords�� fighter aircraft   loading spectrum   flight simulation   special component spectrum
