The Flying-V, a flying wing being designed for air transport, has its wing designed around two cylindrical pressure cabins that are positioned such that they create a “V” shape. The objective of the research presented in this thesis is to create a parametrisation of the Flying-V Outer Mould Line that includes design flexibility and manufacturability, and that can be used in an aerodynamic optimisation routine. To include cabin design flexibility, a cabin parametrisation is created that exists of several oval cross-section cabin trunks for which the length, width, and several height parameters can be specified. The shape of the wing strongly depends on the shape of the fuselage. Manufacturability is included by introducing a constant cross-section wing trunk to the Flying-V design, by using linear lofts as much as possible, and by positioning the loft profiles in line with expected structural frame positions. The parametrisation is coupled with an aerodynamic analysis tool to facilitate future aerodynamic optimisations.
