We had an absolutely perfect day with our tour guide - Rogin Luo - who took us for a hike along The Great Wall! Didn't know what to expect and were thrilled to have him as our guide. Very imformative, knowledgable and fun! We go to experience a part of The Great Wall that was unrestored and see all its natural beauty. Got a long history lesson along the way!

After the hike, we all went to lunch at a small place at the bottom of the hill. Located in a house, we ate lunch in the proprietors bedroom! What a hoot! Rogin is the Best of the Best! This tour company delivered for us and we are extremely grateful.

波音完成787通电 2008年第四季度首飞
 
2008年6月20日——波音公司完成了首架787梦想飞机的整机通电,在实现年底首飞这一目标之前到达了又一个重要的里程碑。

  整机通电是指为飞机接通电源并尝试开始使用电气系统的一系列复杂的任务和测试。


787是更为电气化的飞机,过去的气源,即引气系统已完全被电子系统所取代。

  波音民用飞机集团副总裁兼787项目总经理Pat Shanahan说:“整个团队取得了重大进展,把787的大胆创新变为现实。从现在到首飞前还有大量工作要做,但随着一步步地向前推进,我们越来越有信心。”

  整机通电从六月初开始,进行了一系列测试前连续性检查以确认飞机的布线均已连接妥当。这些检查完成后,波音的工作人员将飞机和一辆外部电源车相连接,从驾驶舱的显示器开始缓慢地将系统每个部分的电载荷增至最大。其后,供飞行员操作的电门将用来向飞机电网中接入新的系统。

  在测试的每一步,电流将通向一个新的区域,使用仪表可确认到达指定区域的电力水平正常。

  沙纳罕说:“我们为保证飞机系统的完整性进行了有条不紊的工作。在完成整机通电的过程中,我们已确信配电系统是按设计安装的并且运行正常。

  第一架787最后的制造工作和运营准备情况的进一步测试还在继续。首飞预计将于第四季度进行。

  波音787梦想飞机是燃油效率更高的中型喷气机,可执飞远程航线。在全面的试飞项目结束之后,787预计于2009年开始收益运营。

  自2004年4月项目启动以来,全世界共有56家客户订购了近900架787飞机,使梦想飞机成为航空史上最为畅销的新型民用飞机。
