Research on component modeling technology of aircraft virtual prototype modelbase

Model base/Data base technology is the basis of virtual prototype system. Based on the aircraft virtual prototype, this paper has a discussion on the function of model base and the key technologies that applied. With the aim to improve the reuse capability and replaceability of the model base, component technology was introduced, and a series of model component standards were established before constructing the aircraft model base. During the development process of the components, software prototype technology was introduced, so that the subsystem components could be developed collaboratively in every development phase.
