Keywords: optimisation, adjoint, aerodynamic design

This paper describes and demonstrates aerodynamic optimisation using the Euler adjoint approach as developed by Jameson on wing/body geometries. This method consists of an Euler flow solver which has been coupled to an integral boundary layer method, an Euler adjoint solver and a simple optimiser. Also described is a new technique for extending the method to more complex configurations, which retains the speed benefit of the structured mesh adjoint technique and combines it with the geometric flexiblity of a viscous-coupled unstructured flow solver. The capability is demonstrated on the W4 wing/body geometry and extended to W4 wing/body/nacelle configuration.
