未来的科学任务将需要200平方米（或更大）的太阳帆。然而，由于地面设施、成本和飞行机会的限制，地面演示和飞行演示的规模必须小得多。因此，理解可扩展性过程的能力，因为它适用于太阳帆系统模型和测试数据，对于这项技术的进步至关重要。本文将探讨太阳帆模型的缩放问题，通过开发一套缩放律或相似性准则，将在帆设计过程中提供约束。这些比例定律建立了以不同几何尺寸创建的原型和模型帆的设计参数之间的函数关系。这项工作适用于一个特定的太阳帆配置和结果在三（四）静态（动态）帆模型的相似性标准。此外，它表明，即使在独特的帆材料的要求和地球上的实验重力负荷的背景下，它是可能的，以开发适当的缩放帆实验。从长远来看，这些比例律可以用于设计太阳帆的比例实验测试和分析这些测试的结果。
Future science missions will require solar sails on the order of 200 square meters (or larger). However, ground demonstrations and flight demonstrations must be conducted at significantly smaller sizes, due to limitations of ground-based facilities and cost and availability of flight opportunities. For this reason, the ability to understand the process of scalability, as it applies to solar sail system models and test data, is crucial to the advancement of this technology. This paper will approach the problem of scaling in solar sail models by developing a set of scaling laws or similarity criteria that will provide constraints in the sail design process. These scaling laws establish functional relationships between design parameters of a prototype and model sail that are created at different geometric sizes. This work is applied to a specific solar sail configuration and results in three (four) similarity criteria for static (dynamic) sail models. Further, it is demonstrated that even in the context of unique sail material requirements and gravitational load of earth-bound experiments, it is possible to develop appropriate scaled sail experiments. In the longer term, these scaling laws can be used in the design of scaled experimental tests for solar sails and in analyzing the results from such tests.
