Rapid aircraft structure modeling based on structure case base

In order to utilize and study more effectively from existing examples of aircraft structure information, the parametric object-oriented description method of structure instance was studied. The architecture framework of aircraft structure case base was proposed and the prototype system was established. The design method of aircraft structure based on structure case base was studied. The parametric modeling method of fuselage structure and wing structure was represented. The functionality of rapid aircraft structure design based on structure case base was achieved in an open conceptual aircraft design system. An instance is given to illustrate the effectiveness of the system and methods.
