Investigation of Aeroelasticity Effect on Missile Separation from the Internal Bay
International Journal of Aerospace Engineering, 2023 There is a strong aerodynamic interference when launching the missile in the embedded mode. During the separation process, the carrier aircraft safety may be threatened due to large slenderness ratio, low structural stiffness, and aeroelasticity effects ...

Aeroelastic Dynamic Response and Control of an Aeroelastic System with Hysteresis Nonlinearities [PDF]
Journal of Control Science and Engineering, 2015 A state feedback control law based on the sliding mode control method is derived for the aeroelastic response and flutter suppression of a two-dimensional airfoil section with hysteresis nonlinearity in pitch. An observer is constructed to estimate the unavailable state variables of the system.
