Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan In this study, direct focusing of repetitive high-power laser pulses on an arbitrary surface of the vehicle in atmosphere were proposed, in which a blast wave was generated at each pulse and pushes the vehicle on the surface inducing an impulse or thrust vector. A fundamental investigation was conducted on interaction of a focused high-power laser pulse, or blast wave, and the surface with arbitrary shape. Numerical simulation on characteristics of impulse, or thrust, vector generation on the surface was conducted. As the first step of the simulation, for simplicity, some fundamental shapes of the surface, or a vehicle, were assumed, which were planar and semicircular bodies, and shock-surface interactions were investigated. As results, a deeper convex vehicle showed largest vertical impulses, and a shallower convex vehicle showed smallest horizontal impulses. 形態: カラー図版あり 形態: PDF Physical characteristics: Original contains color illustrations Physical characteristics: PDF 資料番号: AA0061856099 レポート番号: STEP-2012-016 |
