Abstract: The aim of this thesis was the explore design optimisation techniques that could be used in the optimisation process of the Skylon spaceplane. The research began by investigating the performance of the existing design at a critical design point, the results of which were presented to industry partners. Parameterisation techniques were then explored and a novel mesh morphing framework was developed. The method uses Radial Basis Functions to ensure that a mesh remains suitable for computational fluid dynamic analysis following the application of a morph function to a subset of the geometry. This framework was used to explore optimised designs with the aim of reducing the drag coefficient of the geometry, which was achieved with a reduction in drag coefficient of up to 2% for the Skylon spaceplane at Mach 1.2
