论文摘要
光生力可以无限期地悬浮在地球平流层中的10厘米尺度结构。我们在平流层中的双层三明治结构上开发了热蒸腾力的分析模型。当图层被气隙等于平均自由路径（MFP）时，大约一半的层表面由radii <MFP组成，而当顶层是太阳能传播和发射式弹药时，底层是最大的，而底层则是solar-absorptive-absorptive-absorprared-rrared-trarsansmassmissive。我们使用这些型号设计了一个直径10厘米的设备，其强度足以承受在运输，部署和飞行中可能遇到的力。该设备的有效载荷约为285毫克，高度为25公里；足以支持超过10 MB/s的双向无线电通信和有限的导航。此类设备可能对大气科学或地球和火星上的电信有用。结构大几次可能具有几克的有效载荷。
Photophoretic forces could levitate thin 10 centimeter-scale structures in Earth's stratosphere indefinitely. We develop analytical models of the thermal transpiration force on a bilayer sandwich structure in the stratosphere. Lofting is maximized when the layers are separated by an air gap equal to the mean free path (MFP), when about half of the layers' surfaces consist of holes with radii < MFP, and when the top layer is solar-transmissive and infrared-emissive while the bottom layer is solar-absorptive and infrared-transmissive. We use the models to design a 10 cm diameter device with sufficient strength to withstand forces that might be encountered in transport, deployment, and flight. The device has a payload of about 285 mg at an altitude of 25 km; enough to support bidirectional radio communication at over 10 Mb/s and limited navigation. Such devices could be useful for atmospheric science or telecommunications on Earth and Mars. Structures a few times larger might have payloads of a few grams.
