Transonic Wing and Control Surface Loads Modelling for Aeroservoelastic Analysis

The exponential growth of the aviation sector combined with environmental and energy supply challenges have led companies to innovate to reduce aircraft fuel consumption. Among the many areas currently under research, this thesis investigates the possibility of making aircraft wings lighter thanks to flight load alleviation systems and more...

Unsteady Non-linear Control Surface Modelling for Aeroservoelastic Applications

In this paper, we present a data-driven method to model the unsteady non-linear response of aircraft control surfaces. This method relies on aerodynamic reduced-order models (ROM) derived from computational fluid dynamics with Reynolds averaged Navier-Stokes (CFD-RANS) analysis in the transonic domain. The ROM consists of a combination of look...

Transonic flight and movable load modelling for wing-box preliminary sizing

In this paper, a methodology is presented to size an aircraft wing-box accounting for steady and dynamic loads combined with active control. Several aerodynamic corrections are used and benchmarked to ensure a consistent level of fidelity during the load analysis. Reduced order models (ROM) of the aircraft movables, gust loads and maneuvers...

Prediction of mean flow data for adiabatic 2-D compressible turbulent boundary layers

This book presents a method for the prediction of mean flow data (i.e. skin friction, velocity profile and shape parameter) for adiabatic two-dimensional compressible turbulent boundary layers at zero pressure gradient. The transformed law of the wall, law of the lake, the van Driest model for the complete inner region and a correlation between...
