A coupled Aeroelastic-Flight Dynamic Framework for Free-Flying Flexible Aircraft with Gust Interactions
Nikolaos D. Tantaroudas, Ilias Karachalios
A complete, self-contained mathematical framework for modelling the coupled aeroelastic and flight dynamic behaviour of free-flying flexible aircraft subject to atmospheric gust en…
Nonlinear Flexibility Effects on Flight Dynamics of High-Aspect-Ratio Wings
Nikolaos D. Tantaroudas, Ilias Karachalios
This paper investigates the effects of geometric nonlinearity and structural flexibility on the flight dynamics of high-aspect-ratio wings representative of high-altitude long endu…
Rapid Worst-Case Gust Identification for Very Flexible Aircraft Using Reduced-Order Models
Nikolaos D. Tantaroudas, Ilias Karachalios
Identification of worst-case gust loads is a critical step in the certification of very flexible aircraft, yet the computational cost of nonlinear full-order simulations renders ex…
Nonlinear Model Order Reduction for Coupled Aeroelastic-Flight Dynamic Systems
Nikolaos D. Tantaroudas, Ilias Karachalios
A systematic approach to nonlinear model order reduction (NMOR) of coupled fluid-structureflight dynamics systems of arbitrary fidelity is presented. The technique employs a Taylor…
