“…A detailed analysis shows that this is attributed to a successful shock destruction which allowed to eliminate most of the wave drag. More details may be found in [18] (RAE2822) and in [28] (ONERA M6).…”

“…Novel complex geometries are generally constructed manually which is very time consuming. 35 In order to overcome this automatic mesh constructions are required. CFD ultimately restricts the allowable design space either through computational needs or through how the baseline geometry is allowed to deform with a fixed mesh.…”

A novel population structured genetic algorithm (sGA) with embedded potential flow vortex ring panel method (VRM) has been developed to minimise induced and parasitic drag subject to constraints on lift, root bending moment, and longitudinal static stability. The optimisation architecture can activate up to four independent wing segments allowing up to 28 design variables. Minimum drag of wing tip extensions and winglet configurations are compared using the non-linear stochastic optimisation method. The optimiser identified joined box wings as offering the greatest induced efficiency followed by C-wings. With span and root bending moment constraints winglets offered best total drag reduction. C-wings are further investigated for potential to enhance longitudinal static stability performance by staggering the horizontal extension of the winglet to balance moments around the wing's centre of gravity. Preliminary results suggest that while longitudinal static stability can be reached it would be very poor. Inclusion of more design constraints and additional analysis of the structural dynamics of C-wings, especially effecting the torsional mode, is necessary.

“…Risk assessment and reliability design is an engineering approach widely used for solving system design problems in other fields in which the performed function is important, such as nuclear facilities [29], aerospace [30] and automobile [31] industry, building structures [32], powers systems [33], etc. In this paper, an extension of the reliability-based design approach to the hygrothemal building design is developed.…”
