In the electrodynamic flow control, a weakly-ionized plasma flow behind the strong shock wave could be controlled by the applied magnetic field around a reentry vehicle. It could be an innovative technology for reentry vehicle design because it will realize an aerodynamic control device without moving part. To demonstrate this technology on the flight condition, a light-weight, compact, and strong magnetic field source must be required, which must be able to be magnetized tesla order. We have developed a prototype magnetic field source which contains a superconducting bulk magnet cooled by solid nitrogen and it was applied to some experiments including HIEST wind tunnel test. However, the prototype model has some problems for the magnetizing and cooling processes, which has significant impact on the flight operation. Therefore, the next model is planned to improve and ease the operation by using a Stirling refrigerator instead of liquid refrigerant.
