Abstract: Group evolutionary structural optimisation (GESO) is a recent modification of evolutionary structural optimisation (ESO) which extends the topological method to configuration optimisation. This paper demonstrates the optimisation of an aircraft wing with ESO and GESO. The optimisation is conducted over some of the major areas involved in the design of an aircraft wing. These include the optimisation of the configuration of the internal stiffeners, the sizing of the skin thickness and the detailed optimisation of the stiffeners.

Keywords: aircraft wing design; group evolutionary structural optimisation; configuration optimisation; GESO; ESO.
