Multidisciplinary Simulation for Gust Load Alleviation Control Surface Analysis [PDF]
, 2018 The structural dimensioning of an airplane will be significantly influenced by gust, maneuver and ground loads. Adaptive load alleviations methods (keyword: 1g-wing) promise the potential reducing the maximum loads and therefore the structural weight ...

Coherent Lidar Turbulence Measurement for Gust Load Alleviation
, 1996 Atmospheric turbulence adversely affects operation of commercial and military aircraft and is a design constraint. The airplane structure must be designed to survive the loads imposed by turbulence.

Active Gust Load Alleviation for Flexible Wing Aircraft
, 2017 This paper presents a novel active gust load alleviation approach within a multi-objective flight control framework developed by NASA for a flexible wing aircraft. The aircraft model is based on the NASA Generic Transport Model (GTM). The wing structures

An Unusual Structure for a Feedforward Gust Load Alleviation Controller [PDF]
, 2017 This paper presents an unusual feedforward controller structure that allows to take allocation constraints into account which can be expressed in the time-frequency or time-scale domains. This novel controller structure was motivated by the design of a feedforward controller for airplane gust and turbulence load alleviation based on Doppler LIDAR ...

Gust Load Alleviation Based on Model Predictive Control [PDF]
Weight reduction is a typical design goal for modern aircraft. If gust encoun- ters (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 ...

Decentralized Control of Ailerons for Gust Load Alleviation [PDF]
This paper describes the design of a so-called decentralized gust load alleviation system for an aircraft with high aspect ratio wings. The system uses control loops at each individual aileron actuator that aim to reduce local structural dynamics at each respective point of installation in the wing structure. To this end, each actuator is equipped with
