| Abstract: | High-altitude long-endurance(HALE) aircraft features slender and flexible structures,which under nominal operation conditions may result in large structural deformation,aerodynamic stall,and coupling between the low-frequency structural vibration and the rigid body motion of the aircraft.These nonlinearities and interactions affect dramatically the static and dynamic behaviors of a HALE flexible aircraft.This paper developed a coupled model of aeroelasticity and flight dynamics for high-aspect-ratio flexibl... |
