空客的太阳能飞机已连续飞行逾二十天
2022-07-08 17:43
空客的无人驾驶太阳能飞机 Zephyr S 已连续飞行逾二十天。Zephyr 太阳能飞机最初由 QinetiQ 公司设计，2013 年该公司出售给了 EADS Astrium——今天的空客国防航天。Zephyr S 是最新的 Zephyr 系列太阳能飞机，最大起飞重量 75 公斤，可携带 5 公斤负荷，它长时间在空中停留的能力使其可作为军方的传感器平台。Zephyr S 于 6 月 15 日从美国陆军位于亚利桑那州的 Yuma 试验场起飞，跟踪数据显示它于 6 月 27 日飞过墨西哥湾，接着飞过加勒比海，进入中美洲伯利兹领空，上周回飞美国。Zephyr S 在 2018 年首飞时连续飞行了近 26 天，这一次是否能打破该记录还有待观察确认。

23456789 is the largest prime number with consecutive increasing digits.
> What about the reverse case?
>> 98765431, though I like 98764321 better because it's 2 groups of 4 descending numbers

Elon Musk:
> Yeah, actually not good. Team is assessing damage.
> Cryogenic fuel is an added challenge, as it evaporates to create fuel-air explosion risk in a partially oxygen atmosphere like Earth.
>
> That said, we have a lot of sensors to detect this. More later.
> That is one of the things we will be doing going forward.
>
> This particular issue, however, was specific to the engine spin start test (Raptor has a complex start sequence).
>
> Going forward, we won’t do a spin start test with all 33 engines at once.
> Base of the vehicle seems ok by flashlight. I was just out there about an hour ago. We shut down the pad for the night for safety. Will know more in the morning.
