A Hybrid Quasi-steady CFD-Inflow Approach for Gust Response Analysis of Highly Flexible Aircraft

Abstract

This paper uses geometrically exact, fully intrinsic equations to study the gust response of highly flexible aircraft, including the joined-wing concept. It also introduces a hybrid quasi-steady CFD-inflow model to capture unsteady effects in a computationally efficient method. This is the first step in an attempt to develop a multifidelity program for aeroelastic analysis of such aircraft. Such a program can be used in optimization and sensitivity analysis.

Challenges, Ideas, and Innovations of Joined-Wing Configurations: A Concept from the Past, an Opportunity for the Future

“…The paper [329] presented the first step towards the creation of an in-house aeroelastic code for highlyflexible aircraft including Joined Wings. The structural model was based on fully-intrinsic equations.…”
