SOME RECENT ADVANCES IN NONLINEAR AEROELASTICITY: FLUID-STRUCTURE INTERACTION IN THE 21 CENTURY ABSTRACT Aeroelasticity is the field that examines, models and seeks to understand the interaction of the force from an aerodynamic flow and the deformation of an elastic structure. The forces produce deformation, but the structural deformation in turn changes the aerodynamic forces. This feedback be...

A brief history of developments in the field of low-speed aeroelasticity is provided in the context of application to long-span bridge structures. The paper begins with summary of some of the significant developments in aeroelasticity for low-speed aeronautical applications in the early 20th century. The role of the pivotal Tacoma Narrows failure and subsequent investigation is introduced. The ...

Purpose This paper aims to develop an efficient evaluation method more intuitively and effectively investigate the influence of wing fuel mass variations because burn on transonic aeroelasticity. Design/methodology/approach The proposed aeroelastic is developed by extending standard computational fluid dynamics (CFD)-based proper orthogonal decomposition (POD)/reduced order model (ROM). Finding...

The motivation for Computational Aeroelasticity (CA) and the elements of one type of the analysis or simulation process are briefly reviewed. The need for streamlining and improving the overall process to reduce elapsed time and improve overall accuracy is discussed Further effort is needed to establish the credibility of the methodology, obtain experience, and to incorporate the experience bas...

ABSTRACT This study evaluates the role of supercomputers in large-scale fluid/structure analyses of aerospace vehicles, with an emphasis on computational aeroelasticity dominated by complex fluid/structure interactions. The information presented is primarily based on responses to a web-based survey that was designed to capture the nuances of highperformance computational aeroelasticity and, in ...
