Wing twist optimisation using aerodynamic solvers of different fidelity
Wing twist optimisation using aerodynamic solvers of different fidelity
Computational fluid dynamics has become the method of choice for aerodynamic shape optimisation. However, the computational cost poses challenges for the routine use of high-fidelity flow solvers in the early phase of aircraft design. In this paper, a benchmark wing twist optimisation problem is investigated using two aerodynamic solvers of different fidelity. The first solver is the open-source SU2 software, and the second is an efficient hybrid solver which couples a linear vortex lattice method with an infinite-swept wing solver. Numerical details of two optimisation frameworks are presented. It is demonstrated that the hybrid solver can accurately reproduce the aerodynamic loads on the three-dimensional wing. Optimisation results show that both optimisations can effectively minimise the induced drag by recovering a nearly elliptical lift distribution. In comparison to SU2 optimisation, the hybrid approach achieves a speed-up of two orders of magnitude.

Abstract
Computational fluid dynamics has become the method of choice for aerodynamic shape optimisation. However, the computational cost poses challenges for the routine use of high-fidelity flow solvers in the early phase of aircraft design. In this paper, a benchmark wing twist optimisation problem is investigated using two aerodynamic solvers of different fidelity. The first solver is the open-source SU2 software, and the second is an efficient hybrid solver which couples a linear vortex lattice method with an infinite-swept wing solver. Numerical details of two optimisation frameworks are presented. It is demonstrated that the hybrid solver can accurately reproduce the aerodynamic loads on the three-dimensional wing. Optimisation results show that both optimisations can effectively minimise the induced drag by recovering a nearly elliptical lift distribution. In comparison to SU2 optimisation, the hybrid approach achieves a speed-up of two orders of magnitude.
