日本宇宙航空研究开发机构(JAXA)正在研究将太阳能帆用作深空探测任务的新型推进发动机的可行性。本文提出了利用小型太阳能帆执行任务的帆的形状和设备布置。提出了风帆的两阶段展开方法。第一阶段需要对风帆进行静态展开，并介绍了两种展开机构。另一方面，可以动态地执行展开的第二阶段，并且通过将膜连接到主体的系绳来收敛膜的振荡运动。为了验证展开过程，采用多质点模型对展开运动进行了数值模拟分析。并与有限元模型的计算结果进行了比较。从船帆展开动力学和机构的技术角度对数值模拟结果进行了讨论。
The Japan Aerospace Exploration Agency (JAXA) is studying the feasibility of using the solar power sail as a new propulsion engine for deep space exploration missions. In this paper, the sail shape and equipment layout for missions utilizing small-sized solar power sails are proposed. The two-stage deployment method of the sail is also proposed. The sail need to be deployed statically at the first stage, and two types of deployment mechanisms are introduced. On the other hand the second stage of the deployment can be performed dynamically, and the oscillating motion of the membrane is converged by tethers connecting the membrane to the main body. The deployment motions are analyzed by numerical simulations using multi-particle models in order to verify the deployment. They are compared with the results calculated by finite element method models. The numerical simulation results are discussed from the technological viewpoint of the sail deployment dynamics and mechanisms.
