The relationship between suppliers and aerospace companies is quite complicated, and it is entirely possible that ULA does in fact own the IP that RUAG is using to build 5.4m fairings. This is one of the consequences of outsourcing -- sometimes companies develop manufacturing IP but don't want to do the manufacturing themselves, so they outsource the manufacturing and provide the IP for the use of the vendor. But they still own the IP, and the vendor can't simply use it to build things for other people. Quote Link to comment Share on other sites More sharing options...

I guess they could have bought it from Arianespace, but I doubt that because Ariane probably uses them more often.

Anyway, if appears that the issue is not "5.4 meters" but rather "16.5 meters" (the length of the fairing rather than the diameter). The Ariane fairing is also substantially different, in that it mates to a 5.4m rocket body. Edited July 12, 2019 by mikegarrison Quote Link to comment Share on other sites More sharing options...

CatastrophicFailure Posted July 12, 2019 Share Posted July 12, 2019 Thats gonna be one bold livestream! I wonder if they’ll have scripted remarks specifically if things go all Kerbal.

wumpus Posted July 12, 2019 Share Posted July 12, 2019 22 hours ago, CatastrophicFailure said: I would be most interested to see anything replaced on a running rocket engine. One of the first Falcon 9 flights had an engine failure. It was shut off and the rocket continued on the rest of the rockets. The "SCE to AUX" of legend is a similar thing with electric power. No idea how long a burn would have to be before replacing something in a running rocket would be viable. But replacing something in an ion engine would unlikely to be as exciting as the thread implies (and the only thing I could imagine "burning" long enough to bother replacing hot).

I'm imagining an astronaut hanging on the side of the rocket as the ion engine is running, and thinking "would an ion engine have enough gimbal to offset the CoM shift? Would it matter?"

Ultimate Steve Posted July 12, 2019 Share Posted July 12, 2019 Can ion engines gimbal? I have never heard of them being able to. Quote Link to comment Share on other sites More sharing options...
MinimumSky5 Posted July 12, 2019 Share Posted July 12, 2019 There's no reason why you couldn't, but I imagine that due to the very low thrust of ions, the weight of the gimballing gear would be higher than the weight of reaction wheels that would give the same torque.

Wjolcz Posted July 12, 2019 Share Posted July 12, 2019 Wasn't Dawn's engine offset or at an odd angle? I think I remember seeing an official NASA animation with the engine having some sort of hydraulic structure (presumably for adjustment) around it?

tater Posted July 13, 2019 Share Posted July 13, 2019 If they man rate it, then it flies there itself. Lands, then comes home. or it could drop Orion off at NRHO, because there's so much to do there . Quote Link to comment Share on other sites More sharing options...
