Abstract Dynamic flight simulators (DFS) use a centrifuge to simulate sustained G-loads. The motion planning for the DFS directly affects the accuracy of the G-load simulations. This paper describes a real-time motion planning algorithm for a flight simulator. The G-load simulation model is given but is difficult to solve when the G-loads are negative. A real-time motion planning algorithm with two-dimensional interpolation is used to generate both a trapezoidal G-load curve and three-axis G-load commands. The simulation results show that the simulated G-loads precisely track the commands. The algorithm is accurate and practical.
