【Abstract】 Helicopter design methods, design ideas and managements have been undergoing critical changes due to the application of computer aided design and manufacturing techniques. These changes have increased the level of research interests related to DPA (Digital Pre-Assembly) techniques. In this paper, application of DPA techniques to optimizing the design of helicopter structures is presented, and key arithmetic such as intervention detect and assembly/disassembly of DPA techniques are discussed for the application of DPA to future helicopter development.更多还原
