本文提出了一种轻便、节能的气流控制装置，利用等离子体放电实现平流层飞行。风洞实验是在减压环境中进行的，人们注意到等离子体可以抑制翼型周围的流动分离，从而动态地改变翼型的性能。结果表明，即使平流层飞行的电子平均自由程、等离子体的折合电场和空气动力学雷诺数与地面有很大不同，等离子体在气流控制装置中仍然是有效的。此外，所提出的装置通过简单地将薄带粘附在飞艇的现成机翼或船体上并向其施加电压来操作，这与传统开发的等离子体推进系统形成对比。利用等离子体的气流控制技术将是将人类活动扩展到平流层或更高海拔地区的关键技术。
This paper proposes a lightweight, energy-efficient airflow control device that uses plasma discharge to realize stratospheric flight. Wind-tunnel experiments were performed in a reduced-pressure environment, and it was noted that plasma can suppress the flow separation around an airfoil, thereby dynamically changing the performance of the airfoil. The results demonstrate that even if the electron mean free path, reduced electric field for the plasma, and the aerodynamic Reynolds number for the stratospheric flight are very different from those at ground level, the plasma is effective in an airflow control device. Moreover, the proposed device operates by simply adhering thin tapes on a ready-made airfoil or hull of the airship and applying voltage to them, which contrasts with the conventionally developed plasma propulsion system. The airflow control technique using plasma will be a key technology in extending human activity to the stratosphere or regions at higher altitudes.
