New certified designs for structures are critical for the new upcoming changes in conception of aircraft architectures. A variety of breakthrough designs and new strategies for a better use of material and integration of functions in aircrafts are required. They range from regional electrical mobility solutions to increased aspect ratio wings that will bring higher flexibility in structures. There are a few examples that digital conception and numerical simulation need to play an ever-bigger role to reach a certified design that includes production scenarios before manufacturing can begin.
More specifically, the ambition of the DIDEAROT project is to develop breakthrough numerical approaches ontwo well defined industrial technical challenges contributing to the “Full Digital Twins”:
- Manufacturing processes of composite structures can induce distortions after demoulding. Obviously, these distortions are problematic and difficult to solve. Models must be enriched to better represent material and structural behaviours and their computational efficiency needs major breakthroughs for their use to be convenient and for supporting fast design cycles.
- Damaging behaviour of composite is a key factor in the Design. For small energy impacts, the issue is to determine if the damage will propagate or not. High impact energy is a design driver for different structures (leading edges, nose cone including the cockpit, engines, wings, …). For structures made of composite materials, when they are associated with structures vulnerable to the impact of foreign bodies, these materials require special attention due to their multi-scale nature.
