Needs for analysis and integrated design optimization of active and passive structure for active aeroelastic wings

摘要

Abstract: Active aeroelastic wing concepts, sometimes also called active flexible wing concepts, have been investigated for several years to improve aircraft performance and stability. Two aspects are addressed in these studies: static aeroelastic effects like control surface effectiveness and the redistribution of aerodynamic forces for load reduction or drag minimization, and dynamic aspects like enhancement of flutter stability or reduction of aerodynamically induced vibrations of the structure.!25
