Static Loads Evaluation in a Flexible Aircraft Using High-Fidelity Fluid–structure Iteration Tool (E2-FSI): Extended Version
Journal of the Brazilian Society of Mechanical Sciences and Engineering(2020)
摘要
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.
