Conclusion

The three flight domains thus defined are the reference for regulatory dimensioning in civil aviation. They have the advantage of providing static loads, whereas the phenomena at the origin of these loads are fundamentally dynamic. They can therefore be supplemented by a dynamic parallel approach of the "flexible aircraft" type, which will integrate structural modes (vibrations and response following a transient event) and aeroelastic interactions. Nevertheless, they are sufficient to qualify structures and prepare for certification campaigns, with primary static and fatigue tests compared with the calculation file.
