Gust Load Alleviation with Active Flutter Suppression: Design, Simulation, and Tests

Journal of Guidance Control and Dynamics
Complex aeroelastic phenomena, such as gust response and flutter, pose significant challenges to aircraft design by reducing efficiency, degrading flight quality, and generating structural loads and instabilities with the potential for failure.

Gust Load Alleviation via Active Folding Wingtip Concept: Experimental Approach

AIAA Journal
This paper presents an experimental investigation into gust load alleviation using an actively controlled folding wingtip concept. The system employs a proportional–integral–derivative controller driven by real-time feedback from the wing root bending ...

Passively actuated spoiler for gust load alleviation

2016
This paper summarises a conceptual study regarding a passively actuated spoiler for gust load alleviation. The design of such system is intended to limit the use of computers, sensors and actuators to operate the device. The study mainly relies on using Theodorsen’s unsteady flow theory for a typical airfoil section.

Gust load alleviation using nonlinear feedforward control [PDF]

, 2014
A strategy based on feedforward control for gust loads alleviation of a nonlinear aeroelastic model is considered. The model is representative of a typical wing section with a trailing-edge flap and with a polynomial nonlinearity in the structural model. The aerodynamics is given by thin aerofoil theory. First, the effects of structural nonlinearity in

Nonlinear Folding Wing Tips for Gust Loads Alleviation

Within the scope of sustainable aviation, increasing the operational efficiency and diminishing pollutant emission is a key requirement for future transonic transport aircraft development. In an aerodynamic context, dynamic folding wing tips (FWT) show to possess great potential in the context of future aircraft design. On the one hand the folding wing

Gust load alleviation based on model predictive control

2013
Weight reduction is a typical design goal for modern aircraft. If gust encounters (as required by Certification Specification 25) are sizing conditions of parts of the airframe, this can be achieved (for example) by an active gust load alleviation system that reduces the gust load level down to the level of the next design condition, which might be the
