摘要

太空飞行安全的重要任务之一是机翼在迎面而来的湍流中保持稳定的能力。在这种情况下，航天器必须移动最大的距离。本文研究了在迎面而来的稀薄气体流中靠近边界的薄板的运动。在低雷诺数下，研究了边界对薄板的影响，并显示了自推进的可能性。

Motion and self-motion of thin bodies in rarefied gas

One of the important tasks of space flight safety is the ability of a wing to maintain stability in an oncoming turbulent flow. In this case, the spacecraft must move the greatest distance. The paper studies the motion of a thin plate near a boundary in an oncoming flow of rarefied gas. At low Reynolds numbers, the effect of the boundary on the plate is studied, and the possibility of self-propulsion is shown.
