ABSTRACT
The paper bases on the existing semi-physical real-time simulation environment
for Flight Control System(FCS) of Unmanned Aerical Vehicle(UAV), aims at the
actuality of the output in data and curve form the system,based on the sheory of the
visualization,uses the technique of the modeling,the system running,the model
driving and the munication,designs and achieves the scene graph system
based on Vega Prime real-time simulation system,that could show the real-time flight
process of UAV and provides the truth for researching the flight rule of UAV.
The paper describes the modeling method by Creator, and constructes the model
of UAV, terrain and cabin.
By use of the actual flight data of the UAV, we have driven the flight of the
three-dimension real mould body in the virtual scene, and we have achieved the scene
graph emulation for the flight of the UAV by the alternant function of Vega Prime.
The emulation is effective and brings us a actual sense.
We have employed the develop environment MFC and Tilcon to develop the
interface part of scene graph for the aircraft, also we have designed the button for
controlling the virtual scene. The assistant function of the new module
