Abstract

This study describes the development of an efficient aerothermoelastic computational framework. In the framework, a novel approach is developed for the reduced order model (ROM) of the fluid solver, which accounts for non-uniform temperature distribution and geometrical scales using simple analytical pointwise models. The generation of ROM is accelerated by using a Smart-Ordering scheme. The framework also features the linearized stability analysis and a tightly-coupled scheme, which are used for rapid aerothermoelastic simulation of extended flight time, and efficient identification of stability boundary. The methodology enables an overall cost-reduction of ∼ 5 orders of magnitude, when compared to a CFD-based aerothermoelastic simulation, without compromising accuracy.
