Abstract

The aim of this paper is to investigate the role Reduce Order Models (ROMs) can play in the early phases of aircraft design. During such periods of design, resources (both in terms of hardware and time) available for Computational Fluid Dynamics (CFD) are at a premium. As gust response cases, which are often critical load cases, are traditionally computationally expensive, a tool that allows for rapid, accurate modelling of such cases would be of great use. This paper first looks at the initial development of such a ROM, before exploring methods by which their computational cost can be further reduced. Ultimately this led to the development of a ROM that, for an inviscid wing model, requires approximately a tenth of the resources required by full order CFD simulation to carry out one gust case, and near negligible cost to model further cases at the same Mach number.
