可能隔热真的很烂。。。

越是隔热烂,不越是应该尽量推迟加注、尽量快速加注么?

看起来复材储箱的隔热应该不错

我是觉得他可能需要预冷很久储箱 达到一定状态后一直补着

因地面风关系推迟一日....

High winds have prevented vehicle rollout and launch preparation. Launch for Monday May 22 delayed a day to Tuesday May 23 (NZST). #ItsaTest

小型引擎现在都倾向于3D打印,比如draco和superdraco,可能是因为小部件用传统方法加工困难

也可能不成批量成本太高,3D打印想怎么定制都行

Musk是不是考虑下收购rocketlab,以后Falcon heavy,Falcon 9和Electron就分别叫Falcon Pro,Falcon Air和Falcon Mini

发射时序:

发射前大约6小时将封锁发射场周围区域,之后起竖火箭。
负4小时时加注煤油。
负2.5小时开始加注液氧,箭载计算机将在负2分钟启控火箭倒计时。
负2秒一级9台发动机将点火。
T+2分钟30秒一级关机。
T+2分钟34秒一级分离分离。
T+2分钟36秒二级点火。
T+3分钟7秒抛整流罩。

喷管旁边的那根管子是走冷却燃料的吗?

因气象约束(摩擦起电)继续推迟到明天。

第三次因为天气推迟,看起来云层对碳纤维火箭的影响很大

还真有可能是这个原因,新西兰现在是冬季,空气干燥

Rocket Lab Testing Update ― 24 May 2017

Rocket Lab scrubs test launch attempt from Launch Complex 1

Rocket Lab, an American-New Zealand aerospace company, has postponed the test launch of its Electron vehicle today due to weather conditions. The planned launch attempt will now take place on Thursday, May 25, 2017.

Peter Beck, CEO and founder of Rocket Lab, says poor weather is delaying the launch attempt of Rocket Lab’s first test rocket titled ‘It’s a Test’.

“Similar to yesterday, high altitude cloud created a risk of triboelectrification. Our team were able to fuel the vehicle and prepare it for flight, but worsening weather conditions meant we were forced to delay. We’ll have another go tomorrow. The team did a great job today, and our operations are running smoothly.

“We were targeting a 2pm launch where there was a window clear of triboelectrification, but a front quickly moved up the country and closed the window of opportunity to launch.

“We have weather scientists on site who advise us in real time about changing conditions, as well as using weather balloons and satellite data to assess if launch criteria is met.  

“We’d like to thank local residents, supporters and emergency services for their patience.

“Because this is a test launch, our weather constraints are more restrictive than they will be during commercial operations. We are focussed on the best possible weather conditions for launch. This is so we can focus on testing the rocket as a priority, rather than its ability to deal with adverse weather conditions.

“Safety is Rocket Lab’s number one priority and we are following guidelines set by the FAA and NASA around weather and launch safety.”

During the test phase, it’s common for planned launches to be postponed to ensure ideal conditions. The launch attempt will now occur on Thursday, May 25, 2017.

天气/云层对复材储箱能有什么不利影响??

连续三天都是同样的原因,推测复材储箱更容易积累静电

那以后ITS想高频率发射不是也会遇到同样的麻烦?
