values of L/D by using a CFD solver. We then use this information to construct a mathematical model, which acts a simplified approximation that gives almost the same results as that of a CFD solver but at a lesser time. This way, the L/D ratio of any new geometries is predicted, within a few seconds, without having the need to run an expensive CFD simulation. Such a framework facilitates the economical implementation of GA in solving the present problem. By using the present approach, we were able to arrive at an optimal wing geometry which achieves large regions of attached flow leading to 15% improvement in the L/D ratio as compared to the baseline case.
Even after successfully solving my doctoral research problem, it is hard not to be impressed by the mere possibility of being able to adopt ideas from theory of evolution for solving an aerodynamic problem. The end of this exhilarating journey also reminds me of my humble beginning debut flight of our in-house airplane model, which we thought would be an alien intrusion in the bird’s territory. But to our disbelief, our creation was in the happy company with a group of birds that were flocking together. If only we could approach the efficiency of those natural flyers, the applications become limitless. This work is a step towards that.
