Aircraft electromagnetic launch can increase the take-off speed of the aircraft, increasing the aircraft payload, saving energy consumption and reduced the maximum thrust requirements. Use the "Underground LIM traction on ground vehicle transportation method" for the aircraft electromagnetic launch traction, the “The ring kinetic energy storage with vacuum magnetic levitation rotating shaft support structure " as high-power pulsed power. By engineering the overall design to solve the security and stability of energy supply system, multi backup, high redundancy, high reliability, high power pulse power energy storage system to achieve safe, continuous, reliable linear motor Aircraft ground electromagnetic launch project system.
