Wind Turbine Gust Load Alleviation with Active Flow Control
Energies, 2022 Large wind turbine rotors are becoming more common in utility-scale wind power, especially for offshore wind plants. However, the trend toward large rotors can be limited by their ability to manage dynamic and extreme loads.

Gust Load Alleviation of Flexible Composite Wing [PDF]
CFD Letters, 2020 Gust load due to atmospheric turbulence is mandatory to be considered in aircraft analysis as part of airworthiness requirement. This safety related issue becomes more relevant recently in relation to the global warming that induces more frequent and extreme atmospheric disturbances encountered during air transportation.

Model predictive control for gust load alleviation
IFAC Proceedings Volumes, 2012 For economical and ecological reasons aircraft are required to become more efficient by reducing fuel consumption and CO2 emissions. One way to achieve these objectives is to decrease the weight of the aircraft structure. The reduction is, however, limited by the structural requirement that the aircraft must be able to withstand the forces and stress ...

Gust Load Alleviation Exploiting Structural Nonlinearity [PDF]
, 2017 Gust interaction is a crucial design consideration for civil aircraft. A gust disturbance is defined as any air velocity component normal to the flight path. Gust interactions can rapidly change the aerodynamic forces acting on a wing and in turn the loads on the aircraft.

Adaptive Feedforward Control for Gust Loads Alleviation [PDF]
AIAA 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
Aerospace, 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
