The concept of control node and control equation is introduced for geometrical definition in this paper. The idea of the combined function representation of shape is presented. An important tool of interactive adaptive mesh refinement is developed to achieve an adequate finite element model in the optimization process and to reduce CPU time. A semi-analytical method of sensitivity derivatives calculation is proposed. A shape optimization system of rotating disks (SOPD.BUAA) is developed and applied to design a gas turbine disk. This system is demonstrated by experiments on initial disk and optimal disk.
