The primary structure to be designed and produced constitutes the fuselage front section from radar-transparent nose and cockpit section to junction with the central fuselage. It does not include the doors but include the transparent panel. This structure will be integrated in the LifeRCraft rotorcraft flight demonstrator. Main challenges are to demonstrate light weight and bird strike resistance compatible with airworthiness (TRL6). Please refer to the full and formal topic descriptions published in this call.
