发帖数: 1 | 6 2天2射!SpaceX今天下午发射一箭10星成功,都是大号通讯卫星。首度使用了格栅翼
(grid fin)系统
2017/06/26
今天早些时候,SpaceX 成功地为全球卫星通讯提供商 Iridium 发射了一枚猎鹰 9 号
运载火箭,并顺利完成了火箭的海上平台回收。
美国太平洋时间 6 月 25 日周日,载有 10 颗通讯卫星的猎鹰 9 号火箭从位于加州的
Vandenberg 空军基地起飞,这 10 颗卫星是 Iridium 的 NEXT 计划的一部分,它们
最终将组成一个多达 75 颗卫星的通信网络,建成后其用户可在地球上任何地方与他人
建立联系。
尽管条件困难,SpaceX 最终还是成功将猎鹰 9 号火箭安全降落在海上自主移动着陆平
台之上。发射前 Elon Musk 表示海上着陆平台在后期须要重新定位,这可能会降低一
定的着陆成功率。
在本次任务中,猎鹰 9 号火箭首度使用了钛合金格栅翼(grid fin)系统,该系统能
协助第一级火箭,也就是返回舱进行定位与导航。格栅翼使用钛金属材料制成,好处是
在无需翻新的情况下就能重复使用,从而进一步降低猎鹰 9 号多次使用的成本。... 阅读全帖 |

both of my cars are electric cars. I have been charging my cars

both cars pull max 12A for the outlet. That means each car behaves just like

the grid. This is nothing compare to typical household appliances. For
