Title: The Study of Optimization Method for Axisymmetric Aerodynamic Profile in the Gas Flow by Using Evolutionary Algorithms
Abstract: One of the important and urgent problems of modern aerodynamics is to optimize the shape of a body in a gas flow in order to minimize its aerodynamic drag. The paper considers the possibility of using evolutionary algorithms to optimize the axisymmetric aerodynamic profile in the gas flow. Analytical solution of such problems is possible with the help of conformal maps and only for a narrow range of bodies of simple forms. The presented model is very flexible and can describe a wide range of bodies (profiles) using a certain, minimized number of free parameters. The use of the optimization method by means of evolutionary algorithms allows us to obtain a mathematical model describing the shape of the aerodynamic profile, which easily allows the operator to vary the parameters. It is shown that the value of the aerodynamic drag force for the axisymmetric body of the optimized shape is lower than the values for the bodies of rotation and the known profiles taken for comparison. As a result of the work, simulation modeling of the aerodynamic profile specified in a parametric manner was carried out using the coefficient of the basic profile shape, wing chord thickness parameter and other parameters. The presented simulation results provide a set of necessary coordinates describing the optimized profile structure taking into account the 20% change in the initial geometry #CSOC1120
