Design And Application System For Fundamental Database Of Helicopter

Fundamental database of Helicopter is not only one of the most important components in the basic architecture of helicopter's digital design, but also the basis of digital supporting environment. To establish the general fundamental database of Helicopter is a significant link in getting through the digital production line because supporting of various kinds of the fundamental data are needed in both of the main flow of parallel digital definition and assist flow of experiment simulation. A fundamental database and application system utilizing advanced data management technology is designed to meet present data management demands.According to application requirements, the Browser/Server framework is adopted and Oracle is used as the database management system of the database server. Various kinds of the fundamental data are integrated and shared in order to build a single source of product data and meet the requirement of integration and operation. On the base of investigating the requirements, the design work of concept model, logic model, physics model, physics implement are fulfilled. On this basis, the program of the application system is designed in .NET environment, which uses three-layer structure. Furthermore, DLL(dynamic link library) interfaces are developed for the data access and transmission of digital systems.The system not only meets the needs of users of providing an effective way for helicopter's digital engineering, but also helps to take full advantage of helicopter data, enhance data share and guarantee data security.
