安装船尾横梁

我的清洁和维修是贝克水翼刚体式机翼帆的方法，但我认为现在是时候将我们安装的船尾横梁进行联系了。您可能还记得，当Oracle团队组装AC72平台时，他们将三个中央结构连接起来，然后将它们作为一个单元降低到船体上，并且由于天花板的高度和可能的重量限制，我们无法做到这一点。由于横梁的形状以及需要去的地方 - 放在船体上并塞在中央吊舱的末端，我们知道我们需要比可用的船体更清晰。

因为我们不得不拿起严厉的横梁和密苏里州ve it about ten feet to get it into position we used our gantries. This meant having to disassemble them afterwards but using chain falls severely hampered our maneuverability. We lifted the crossbeam and moved it as close as possible to its final seated position. At that point I crawled into the hulls and loosened the bolts at each end of the forward crossbeam. This allowed us to lift the aft end of the central pod about a foot or two and the forward crossbeam about six inches (we didn’t want to raise it too far because we didn’t want the hulls shift position and misalign the connection points). Then, with five people working together (two operating chain falls on the forward crossbeam, one on the chain fall at the aft end of the central pod and two on the gantry chain falls) we slowly tucked the crossbeam into the back of the central pod and gently lowered all three pieces onto the hulls.

该过程完美无缺，除了必须钻出一种方式以对中央吊舱施加一点压力（将其拉向赫尔港），我们不得不进行很少的操纵才能使所有连接点排队。然后，我重新安装了前向横梁中的硬件，并在船尾连接到船体的点上安装了新硬件。我还安装了将前向横梁连接到匕首板井的船体的螺栓。接下来，将硬件安装在中央吊舱和斯特恩横梁之间的连接点上，这是一个有趣的经历，只要这样做的人不是幽闭恐惧症（值得庆幸的是，我不是）！
