Yes you could pretty much fit an half length shipping container inside it and they make an longer version Now having an wire you could pull and an rubber fabric at the bottom part and you could float this very well. Still I guess splashdown will get so much seawater inside you need an full refurbish anyway. Quote Link to comment Share on other sites More sharing options...

Delta dart Posted October 8, 2020 Share Posted October 8, 2020 Do yall think that the first super heavy booster will be a hopper like Grasshopper and Starhopper because I think it will be unable to mount starship on top of it and will just have a nosecone and be like F9R (anybody remember f9r) as both of the hoppers have fixed landing gear and the latest super heavy design has landing gear. I guess we'll know in a bit because we have images of the pieces of the booster. Quote Link to comment Share on other sites More sharing options...

I guess we'll know in a bit because we have images of the pieces of the booster. There's only going to be 2 engines, so I think it's safe to assume something like that. Even the second/third/however many boosters they need before they're comfortable with an orbital flight. On a side note, I'm personally thinking less than 5. They probably don't want too much of a gap between Starship and Superheavy tests, so I'm wondering if the testing phase will be more ambitious, with an increasing number of engines on each booster.

I believe there was a video a few pages back of a fin articulation test. They flap quite merrily. Quote Link to comment Share on other sites More sharing options...
tater Posted October 9, 2020 Share Posted October 9, 2020 (edited) The big rolling transporter thing apparently went to the pad at Boca Chica...

Maybe they are gonna take SN8 back to the barn to get a nose? Perhaps it's just going to wheel SN7.1's transport mount back, it's still at the launch site. I'd expect them to just bring the nosecone to the launch site once it's finished, no point taking SN8 all the way there and back if they can just take the nosecone there in one shot.

tater Posted October 9, 2020 Share Posted October 9, 2020 Any new fan render should use the dimensions of the observed header tank spheres and seamlessly fair those into the nose cone AS the tip. Quote Link to comment Share on other sites More sharing options...

Right now the tip of the nose is a ^ on top of a o (the header tank). Upside down, but like this: Instead of that dead space between H and A in the diagram above (header tank of radius r), the nose will be a truncated cone with the header tank literally being the tip of the nosecone. Ie: the nosecone will approach the header tank on line BF in the diagram, and the curve of the sphere is the tip. Quote Link to comment Share on other sites More sharing options...

Look at the fairings above, it would not be much problem making them more pointed, yes it would add a bit more weight but not significantly so.

Yeah, because their Mach cone is so *very* pointy that it's not worth it. The higher the Mach number, the more pointy the Mach cone. Quote Link to comment Share on other sites More sharing options...

Look at the fairings above, it would not be much problem making them more pointed, yes it would add a bit more weight but not significantly so. Rockets often have stubby noses because they spend very little time in dense parts of the atmosphere during supersonic flight. A supersonic fighter jet needs low drag for sustained level supersonic flight. Quote Link to comment Share on other sites More sharing options...
tater Posted October 9, 2020 Share Posted October 9, 2020 Yep, and the other goal here is reduced mass. "The best part is no part." Why add a fairing over a rounded header tank if the tank itself can be the nose? (and the tank has good reason to be spherical) Quote Link to comment Share on other sites More sharing options...
