Static loads evaluation in a flexible aircraft using high-fidelity fluid–structure iteration tool (E2-FSI): extended version

Abstract

This paper presents a fluid–structure iteration method applied as a study case to a conventional transport aircraft with wing aspect ratio of 12. It evaluates the nonlinear structure effect on the calculation of static limit loads. The numerical tool presented herein is named E2-FSI, which stands for nonlinear high-fidelity static fluid–structure iteration, developed for high flexibility static aeroelastic evaluations. A discussion about the use and the applicability of high-fidelity static fluid–structure iteration for the calculation of static loads is presented as part of the conclusion, for both current and future conventional transport aircraft.
