| In the three types of electromagnetic launch, Reconnection gun combines the advantages of rail gun and coil gun, which can launch massive projectiles and achieve ultra-high speed. It is considered the best prospect type of electromagnetic launch. However, the levitation force provided by drive coils is interrelated with the amplitude of excitation current. When the drive coil excitation current is 0, the drive coil can not provide levitation force. So the assistant suspension device is need to ensure the stability suspended state of projectile, and don't collide and rub with the drive coil. Superconducting Maglev electromagnetic launch technology has the characteristic of "great carrying capacity, a large suspension gap, friction-free, low power, low maintenance, safe and reliable, low pollution". It is an ideal method of launch. The core technologies of superconducting Maglev electromagnetic launch include magnetic levitation systems, propulsion systems and high power pulse power system.This paper firstly analyzes the characteristics of three traditional permanent magnetic maglev rails. Halbach arrays rail could provide the highest surface magnetic field, levitation force and guidance force, but the internal structure is most unstable and hardest installation at the same time. So, the Horizontal Magnet rail is used widely at present. Combining the characteristics of magnetic field distribution of Halbach arrays, this paper designed a new type of magnetic levitation rail:advanced Halbach structure permanent magnetic maglev rail. This new type of levitation rail, not only retains the characteristics of Halbach structure to provide strong magnetic field, but also solved the problem of instability.In propulsion, aiming at the problem of the interval of two adjoining power excitation longer and effective acceleration time shorter in reconnection gun, this paper proposes a continuous pulsed magnetic traveling wave launch. It generates a continuous magnetic traveling wave in temporal and spatial. The projectile followed with the motion of magnetic traveling wave. The interval of excitation is shortened. And the projectile could be quickly up to speed. From the principle of continuous pulsed magnetic traveling wave propulsion, the paper obtains two forms of driven coil layout suitable. The driven mode, requirement of drive current wave forms, requirement of pulse interface are discussed. The effect of continuous pulsed magnetic traveling wave propulsion is simulated and compared with the reconnection gun. Calculations show that continuous pulsed magnetic traveling wave propulsion can improve the emission rate, shorten the launch time, and increasing the emission efficiency. In the pulse power, capacitance energy storage has leakage current and can't save energy with a long time; inductance energy storage should use breakers, and high voltage is easy to be produced during the energy releasing. Furthermore, the breakers are difficult to achieve great current and high power. To solve these problems, this paper designs a modularization high-temperature superconductivity inductance pulse output circuit. This circuit uses superconducting inductive energy storage to increase the energy storage time and density, uses modular technology and pulse transformer to make up for the insufficient of breaker, and uses MOV to prevent over-voltage on the superconducting inductor. This article mainly discusses the output current waveform of a single module/multi-module. The Generator circuit of electromagnetic emission drive current is designed. And the circuit parameters of the matching problem are analyzed by simulation. Furthermore, the mutual inductance coupling among energy storage inductors in multi-module integration are analyzed and dealt with.Finally, the suspension system, propulsion system and pulse power system designed by this paper are assembled and simply experiment tested. The feasibility of HTS continuous pulse magnetic wave electromagnetic launch is verified.
