Influence of Wing Elasticity on Gust Load Alleviation of an Airliner
Journal of AircraftAlleviation of gust-induced loads enables the realization of a lighter and more flexible aircraft structure, reducing the overall fuel consumption and increasing passenger comfort. Within this work, dynamic deflection of leading- and trailing-edge flaps,

Gust load alleviation in a flexible smart idealized wing
Aerospace Science and Technology, 2019Abstract Among the aeroelastic phenomena most commonly affecting flexible and very flexible aircraft, those caused by gusts deserve special attention due to their potential either in degrading flying qualities and ride comfort or in increasing structural loads. It is then of interest to structural loads and flight controls engineers that solutions be

Gust Load Alleviation on a Large Transport Airplane
Journal of Aircraft, 2016This study develops an active control technology to reduce the incremental dynamic loads of a large four-engine transport airplane flying through a gust field. The mathematical model of the proposed gust-alleviation system features composite structural motions (for example, rigid-body motions, elastic vibrations, and deflections of control surfaces ...

Hybrid adaptive control for gust load alleviation
2015 34th Chinese Control Conference (CCC), 2015This paper develops a hybrid adaptive control (HAC) framework based on fast block least mean square (FBLMS) algorithm for gust load alleviation (GLA). Currently, the GLA control system is usually focusing on the alleviation of structural vibration of aircraft caused by turbulence perturbation.

On the effect of enforcing stability in model predictive control for gust load alleviation
2015 American Control Conference (ACC), 2015Gust load alleviation control refers to the task of attenuating loads acting on an aircraft flying through turbulence. Simulation studies have shown that model predictive control based gust load alleviation strategies can lead to significant load reduction.

Gust Loads Alleviation Using Special Control Surfaces
Journal of Aircraft, 2007Control laws are designed for the alleviation of dynamic gust loads on a wind-tunnel model of a transport aircraft using wing-mounted control surfaces. Three different control surfaces are used: the symmetrically actuated main ailerons, special underwing forward-positioned control surfaces at about 0.8 of the wingspan, and special wing-tip forward ...
