The creation of artificial gravity is considered essential for long-term human spaceflight to mitigate the adverse health effects of weightlessness, such as muscle atrophy and bone density loss. The most practical proposed method is to use 离心力. By spinning a spacecraft or a section of it, an inertial force is generated that pushes everything inside towards the outer wall. From the perspective of an astronaut in this rotating frame, this outward push is indistinguishable from gravity. The strength of this “gravity” depends on the radius of the rotating structure and its rate of spin. A larger radius allows for a slower rotation rate to achieve Earth-like gravity ([latex]1g[/latex]), which is desirable to minimize disorienting effects like the Coriolis effect. For example, a structure with a radius of 224 meters would need to rotate at 2 revolutions per minute (RPM) to simulate 1g. Smaller radii require much faster rotation, which can cause motion sickness and other physiological problems. This trade-off between size, structural mass, and physiological comfort is a major challenge in designing rotating spacecraft.
这一概念最早由康斯坦丁·齐奥尔科夫斯基于1903年提出。后来,沃纳·冯·布劳恩和其他航天先驱将旋转设计融入到他们设计的空间站和星际飞船方案中。虽然目前还没有建造出配备完整人工重力系统的载人飞船,但许多设计研究,例如斯坦福环形体和奥尼尔圆柱体,都探索了大型旋转居住舱的可能性。在较小规模上,地面离心机被用于训练飞行员和宇航员承受高重力,并研究超重力对生物体的影响。
