| Outline of Final Research Achievements |
A flight performance of an aerospace vehicle can be improved using a remote energy transfer because beam-induced shock wave and plasma changes a flow field around the vehicle. A numerical simulation was conducted to understand a discharge physics, which implied that a radiation transfer and a thermal ionization process played an important role on the plasma-front propagation. Moreover, the beam irradiation and discharge experiments indicated that a lift performance of the aerospace vehicle can be improved.
