This work proposed a surface discretization method to attain fast parametric structure modeling for complete aircraft configurations. The geometric model is established in a discretized way at the beginning of parametric modeling process instead of being discretized after finite element (FE) analysis is started. Then FE meshing becomes faster and more likely to succeed, and the design zones can be easily grouped. It’s successfully applied in modeling supersonic transport, tailless fighter and flying-wing bomber.
