Design of Virtual Simulation Environment for Large-scale Transport Aircraft Integrated Training Simulator

The transport aircraft integrated training simulator has the characteristics of complex flight scene, many virtual instruments, large amount of information for man-machine interactive and so on. Setting up virtual simulation environment is vital for the simulator development. This paper introduces the architecture of the integrated training simulator and the development method of the virtual simulation environment. It also uses the method of dynamic interpolation for the whole flight envelope pneumatic para...
