Airworthiness certification for next-generation aircraft
Stringent regulations for reduced emissions adds complexity to airworthiness certification for next-generation aircraft. Innovative aircraft architectures and lightweight structures that use composite materials, for example, bring uncertainties around the aircraft structural dynamics performance.
Electric propulsion systems offer further possibilities for disruptive vertical take-off and landing (VTOL) aircraft configurations and new urban air mobility concepts. These innovative designs increase the workload required to validate and tune their performance, while time constraints remain. Engineers are under pressure to meet program deadlines while lacking experience and data about the aircraft structural dynamics performance.
