Noise-robust modal parameter identification and damage assessment for aero-structures (2024)
Journal Article

Purpose
Ground vibration testing is critical for aircraft design and certification. Fast relaxed vector fitting (FRVF) and Loewner framework (LF), recently extended to modal parameter extraction in mechanical systems to address the computational cha...

Active stall flutter suppression for a revised Leishman-Beddoes Model (2023)
Journal Article

This paper proposes a nonlinear disturbance observer (NDO)-based sliding mode control (SMC) method to the problem of stall flutter suppression for a revised Leishman-Beddoes (L-B) model. To capture accurate aerodynamic characteristics whilst reducing... Read More about Active stall flutter suppression for a revised Leishman-Beddoes Model.

Ground vibration testing of a flexible wing: A benchmark and case study (2022)
Journal Article

Beam-like flexible structures are of interest in many fields of engineering, particularly aeronautics, where wings are frequently modelled and represented as such. Experimental modal analysis is commonly used to characterise the wing’s dynamical resp... Read More about Ground vibration testing of a flexible wing: A benchmark and case study.

Aeroelastic damping estimation for a flexible high-aspect-ratio wing (2021)
Journal Article

Estimation of aeroelastic damping for a very flexible high-aspect-ratio wing using wind-tunnel test data is presented in this work through the comparison of four different methods: half-power, half-quadratic gain, an adapted version of random decreme...
