Abstract

In spite of the fact that first historical aircrafts were designed and sized with static or quasi-static considerations, it appears clearly that dynamics of structure is the major challenge for mechanical design of modern and future Identified Flying Objects. The classical notion of “strength” is now generalised to mechanical quality including dynamic requirements and correlative regulation for qualification or certification. This criticity is due to several parameters converging towards safety and performance of power in crafts, including speed, range, commercial capacity, and global good use of available energy. The major points are here : the increasing of material use (generating light, thin and performing structural assemblies, eventually non-linear), the “size effect” (inducing new mechanical performances), the parallel research of safety, and the respect of environment. The modern tools of mechanical engineering are now all mandatory to deal with these requirements, which are convergent for civil and military applications. For instance, the environmental parameter for civil aircrafts is in relation with furtivity for military crafts (including dynamics and noise).
