Even the engine section looks like it needs a good scrub and is as good as new... I recall that was one of the big upgrade points on B5, since it was taking so much damage before. I wonder why they’re still pulling the legs off, tho? They’ve obviously gotten the folding thing at least partly working. Quote Link to comment Share on other sites More sharing options...
Elthy Posted September 16, 2018 Share Posted September 16, 2018 The metallic ring which holds the rocket for transport seems like it would collide with the legs. They propably are building an alternative allready... Quote Link to comment Share on other sites More sharing options...

Elthy Posted September 16, 2018 Share Posted September 16, 2018 My guess: They were not sure about the final design of the legs (maybe they arent even now) and dont want to replace all the hardware... Quote Link to comment Share on other sites More sharing options...

They won't add a collider to this part, so the legs will just pass through it. That's the plan.

Are we not at all concerned about the really big fins near the front affecting the stability of the rocket? Or even the canards? Looks great but it feels like it would prone to flipping.... Abort motors are good though. Quote Link to comment Share on other sites More sharing options...

Abort motors are good though. It looks like the canards fold up. With good flight control software, they might even be what stabilizes those great big fins effectively in the middle of the rocket until the booster separate. (Kerbal isn't always the best example with such) I have to assume SpaceX has some really smart people who've figured the aerodynamics out. The fact that they now have those canards, and folding fins to execute that tricky flip, is pretty good evidence of this. Like Musk has said previously, full aerodynamic control and stability during re-entry, between the canards and the fins I think they've got that, now.Theoretically, of course...

tater Posted September 17, 2018 Share Posted September 17, 2018 BTW, stage 1 gridfins were disabled in the render, apparently. Sorry for my Musk tweet repost, I didn't see the earlier posts on my phone for some reason. 7 hours ago, CatastrophicFailure said: Definitely canards up front. And I swear those look like pods for abort engines too. No way it gets LES for the whole stage 2. That would require an insane amount of instant-on thrust.

Not for the whole stage two, just for a separable (maybe gliding, with those canards?) crew module, as some have pointed to needing for NASA (or anyone else) to trust the thing with people, at least at first.

I could see a pod, yeah. I wasn't seeing anything that looked like that in the image, though. Quote Link to comment Share on other sites More sharing options...
