ADVANCED MULTIDISCIPLINARY DESIGN OF NEXT-GENERATION GREEN AIRCRAFT

This study presents an advanced Multidisciplinary Design Optimization (MDO) tailored for the design of next- generation green aircraft, integrating innovative propulsion systems and advanced materials. The MDO is based on an advanced Class III weight estimation method. Traditional Class I and II methods were inadequate for contemporary green aircraft, necessitating a sophisticated approach to accommodate new concentrated masses and materials. The Asymmetric Subspace Optimization (ASO) method was employed to balance computational loads effectively across disciplines such as aerodynamics, structures, and propulsion systems. Preliminary results for a hybrid electric/traditional regional aircraft have shown significant performance improve- ments, including a notable reduction in fuel mass and an increase in lift-to-drag ratio.
