It is a new experience to apply magnetic levitation technique to thrust measurement for rocket engine. A brief introduction of the test-bed structure is given first, and the mathematic model of the whole system is developed then. Finally, some simulations based on the model developed are also taken to verify the per formances of the whole system. Several in-situ experiments have been done successfully. Both the simulation and the experiments results show that the magnetic levitation technique can improve the performances of the test system for rocket engine greatly.
