recommendations! Published in 2024 at "CEAS Aeronautical Journal"

DOI: 10.1007/s13272-024-00782-2

Abstract: Lifting propellers operate at oblique inflow and thus encounter severe dynamic loads during forward flight, impacting structural integrity, fatigue, and vibration. Numerical optimization approaches consider aerodynamic, structural mechanical, and aeroacoustic aspects within preliminary design. To… read more here.
