The Realization of Virtual Reality of Launching Rocket Based on Simulink and VRML

Abstract ¾ The course of simulation is establishing mathematics model of exterior ballistics、creating simulation platform using SIMULINK and establishing 3D visual scene using VRML（Virtual Reality Modeling Language）and V-Realm Build 2.0. The input signal can be accepted by output module of VR Sink, because of the technology of combination of SIMULINK and VRML. It can display the movement of rocket in the way of virtual reality. The flight trajectory reflects the flight state of rocket. The technology of Virtual Reality is significant for designers to design exterior ballistics of rocket.
