“…As one of the popular artificial intelligence methods, genetic algorithms represent search algorithms based on the mechanics of natural selection and natural genetics [21]. Until now, they have been used for many optimization tasks, particularly combined with other techniques of artificial intelligence, as it is shown in [22,23,24]. The basic GA optimization cycle is shown in Fig.…”

“…The analysis showed the possibility of controlling instability speed, mass and gust response in an advantageous manner by controlling the structural shape. Later Vio et al 8 explored further this concepts of wing box deformation by fitting third order Non-Uniform Rational B-Splines (NURBS) to the rear and front spar of a sweptback tapered wing box. The optimised design was seen to be different to straight spars/ribs structure design and had improved mass, instability speed and gust response.…”

“…The use of coupling phenomenon through either stacking sequence optimisation [4][5][6][7][8] or novel manufacturing methods 9,10 have shown the possibility of a large positive impact on the aeroelastic performance. However, the idea of aeroelastic tailoring has mainly been investigated on conventional structural designs 6,7 .…”

Wing aeroelastic performance, such as static aeroelastic shape, flutter/divergence speed and gust load response, has a critical impact on aircraft design and consequently the tailoring of aeroelastic response offers much potential for weight savings. In this paper, the configuration between the spars and ribs of an un-tapered, un-swept wing box is varied to modify the aeroelastic performance. Different spar/rib orientations are investigated through numerical simulation and an experimental test program using 3D printed wings. A series of static and dynamic wind-off and wind tunnel tests show that it is possible to have a significant influence on the structural behaviour.

“…Furthermore, several papers on the use of aeroelastic tailoring in general and its potential benefits, have been written recently by Weisshaar. [4][5][6][7] More specifically, research has been done on the use of aeroelastic tailoring in order to minimize structural weight, [8][9][10][11] maximize flutter speed, 10,[12][13][14][15] optimize the gust response characteristics of the wings, 16 or the effect of tow-steered composites on wing aeroelastic characteristics. 17,18 Several researchers [19][20][21] have used a gradient-based optimiser with adjoint sensitivities to achieve aeroelastic tailoring by optimising a combination of laminate thickness and the fraction of 0 deg, 45 deg, −45 deg, and 90 deg plies in the stacking…”
