摘要 为有效提高空间太阳能聚光器的聚光效率,提出了一种用于太阳能热推进器的具有伞状龙骨结构的可折叠展开式抛物面太阳能聚光器设计方案,该方案可以克服充气展开式抛物面聚光器和刚性固定抛物面聚光器具有的技术难题。设计了一个聚光功率100 kW,开口圆半径4.9 m的可折叠展开式伞状龙骨结构正焦抛物面聚光器,利用Fluent软件,对太阳能热推进器进行了模拟和性能预示,以氢气为工质气体,得到系统的推力和比冲可以分别到达10.23 N和701.4 s。结果表明:这种推进器具有比冲高、推力适中的特点,可以用于微小卫星、纳卫星的轨道转换及姿态控制。 A deployable umbrella-shaped keel concentrator has been proposed for the solar thermal thruster(STP) system.The improved concentrator overcomes the shortcomings of traditional inflatable concentrators and rigid fixed concentrators.A deployable solar paraboloid concentrator has been designed.It adopts the collapsible umbrella-shaped keel with a concentration power of 100 kW and an aperture radius of this 4.9 m.The performance of the STP system equipped with this concentrator has been investigated with the software Fluent.The results reveal that the thrust and specific impulse can reach 10.23 N and 701.4 s respectively,indicating this system is applicable to attitude control and orbit transfer for micro-and nano-satellites.
