Gust Load Alleviation with Robust Control for a Flexible Wing [PDF]

open access: yesShock and Vibration, 2016
Traditional methods for gust alleviation of aircraft are mostly proposed based on a specific flight condition. In this paper, robust control laws are designed for a large flexible wing with uncertainty in Mach number and dynamic pressure.

Adaptive Feedforward Control for Gust Loads Alleviation [PDF]

open access: yesAIAA Atmospheric Flight Mechanics Conference and Exhibit, 2008
In this paper, an adaptive feedforward control framework is proposed for the suppression of aircraft structural vibrations induced by gust perturbations to increase the resilience of the !ight control law in the presence of the aeroelastic/aeroservoelastic interactions. Currently, aircraft with nonadaptive control laws usually include roll-off or notch

On the Aeroelasticity of a Cantilever Wing Equipped with the Spanwise Morphing Trailing Edge Concept

open access: yesAerospace, 2023
This paper studies the aeroelastic behavior of a rectangular, cantilever wing equipped with the spanwise morphing trailing edge (SMTE) concept. The SMTE consists of multiple trailing edge flaps that allow controlling the spanwise camber distribution of a

Incremental Nonlinear Control for Aeroelastic Wing Load Alleviation and Flutter Suppression

open access: yesActuators, 2023
This paper proposes an incremental nonlinear control method for an aeroelastic system’s gust load alleviation and active flutter suppression. These two control objectives can be achieved without modifying the control architecture or the control ...

Nonlinear Folding Wing Tips for Gust Loads Alleviation [PDF]

open access: yesJournal of Aircraft, 2015
A recent consideration in aircraft design is the use of folding wing tips with the aim of enabling higher aspect ratio aircraft with less induced drag, but also meeting airport gate limitations. This study builds on previous work investigating the effect of exploiting folding wing tips in-flight as a device to reduce dynamic gust loads, but now with ...

Gust Loads Alleviation Using Sloshing Fuel

open access: yesAIAA Scitech 2021 Forum, 2021
There is much interest in developing concepts to reduce in-flight loads resulting from gusts and atmospheric turbulence, as this will lead to lighter aircraft with improved fuel performance and reduced environmental impact. Recent work has considered using sloshing in tanks as a means to increase the effective structural damping in the wings ...
