Virtual Prototyping is a new conceptual technology, which based on the integration of CAD/CAM, system simulation and visual reality technologies. In future, it will be the main measure for design、running、test and appraising in the areas of flight vehicle design. The system framework and design environment of virtual prototyping for flight vehicle is described. Firstly, some elementary concepts, background knowledge, functions and design demands are discussed in detail. Secondly, the system structure that includes software framework、model library、simulation database、visual subsystem and distributed computer architecture are discussed. Thirdly, according to the development level of computer technology and the test and design of flight vehicle, the study and developing task are given as follows: * Founding the software framework that is used for the modeling and simulation of flight vehicle. * Designing the administer mechanism of model library and database for the virtual prototyping. * Developing the hardware system and distributed calculating software library, which are used for the complex virtual prototype. * Founding the visual subsystem used for displaying the virtual prototype.
