| Abstract: | This paper starts with the engineering application of a trade-off between the aerodynamic characteristics and aircraft design requirements in transonic wing design,and proposes a two-step design strategy which combines the wing planform optimization and wing section optimization based on the constraints of constant structure weight and volume.Using the neural network and genetic algorithm,a corresponding design method is set up.For the transonic wing design using the two-step optimization method,improvement... |
