Yidoyu and Its Application to Aircraft Design

Abstract : This paper is to introduce the essential techniques, special points, and a sketch on the procedure organization of the multi-constraint design optimization system for aircraft structures (YIDOYU), and also to reintroduce the present status of its systematic applications. From the results of some actual examples, YIDOYU is shown to be a practical design optimization system to have ability and efficiency in solving different structural optimization problems....
