Study On Flight Simulation System Based On Distributed Virtual Reality

Flight simulation system plays an important role in aircraft design, performance analysis and training of pilot. Based on the study status at present, the dissertation determines the flight simulation system combined with distributed virtual reality (DVR) and traditional simulation methods as the emphasis.According to the basis design principles of DVR, a design scheme of the whole simulation system is proposed. Through studying several coordinate systems of the flight dimension and the conversion among them, the article carries out a conversion of the parameters from the flight dimension to the virtual scene. Utilizing VRML, a perfect 3D virtual environment is established. The track of the moving object in the scene can be controlled through generating VRML animation and interacting with the users. In the end, an interface between the scene and external Java program is performed, furthermore, flight data in network databases can be accessed.Ultimately, a 3D demo system is established based on the browser/Web server mode, which provides a feasible method to found a flight simulation system ground on Internet. All the software of the system is programmed using VRML and Java, which can be transplanted easily.
