sevenperforce Posted February 10, 2021 Share Posted February 10, 2021 Because I apparently have nothing better to do.... Spoiler The larger pictures don't have any rotation on the tiles but I did this other one as well to show that rotation is possible. Quote Link to comment Share on other sites More sharing options...

There is huge benefit in a few tile shapes reused, but maybe a few "meta tiles" could be designed such that the remaining areas fill in with fewer gaps? Not going from 2 unique tiles to 2000, but from 2 to... 3, or 4, where the added non-hex tiles are shapes forms of the gap shapes, and could possibly even be curved, or slightly "bent" along a midline so the edges match better.

KSK Posted February 10, 2021 Share Posted February 10, 2021 That should help move crewed Starship development along. And if they have a lunar capable Starship flying by then, I’m sure Elon will be quite happy with 300 million to put towards the Mars capable version. Maybe he’ll accept it in Bitcoin.

Not all of the $300m is going to SpaceX, that's just how much it costs to NASA in total. Quote Link to comment Share on other sites More sharing options...
KSK Posted February 10, 2021 Share Posted February 10, 2021 Oh, okay. That’s not how I read it but it’s not worth arguing about. A nice chunk of change to SpaceX either way I’m sure! Quote Link to comment Share on other sites More sharing options...
tater Posted February 10, 2021 Share Posted February 10, 2021 For my own reference: Shuttle had ~24,300 unique tiles. Regarding the landing legs... for Earth, who knows, but the lunar version could just as well copy the TWA Moonliner at Disneyland: No need for the slots, the rails can be on the surface. The stance could be quite large. they don't have to deploy moments before landing, they deploy slowly. Adjusting the position via the rail (worm gear?) allows self-leveling.

My guess is that they invert the legs and go for an falcon 9 style system. Yes you would need hydraulic for the pistons for self leveling but that could double as dampeners.

How would they achieve something like that without seams in the heat shield? It seems like they're really trying to avoid that. Quote Link to comment Share on other sites More sharing options...

Yeah, I'm thinking 5-6 tiles. Large hex, medium hex, small hex, "keyhole"/"meta", and truncated versions of the large hex for edging. I don't think curvature is necessary for the keyhole tile, though. 3 minutes ago, RealKerbal3x said: How would they achieve something like that without seams in the heat shield?

tater Posted February 10, 2021 Share Posted February 10, 2021 The benefit of a worm-gear driven setup is that the F9 legs have 1g to help drop them. Deploying the legs well in advance is not a problem for the lunar application, and it seems like leveling would be very straightforward with such a system.

cubinator Posted February 11, 2021 Share Posted February 11, 2021 Center core gets expended anyway even if it lands because it's cursed Quote Link to comment Share on other sites More sharing options...
RCgothic Posted February 11, 2021 Share Posted February 11, 2021 (edited) It'll probably be a dual ASDS landing for the side cores with centre core expended. 15t is comfortably within FH's GTO expendable capability of 26.7t, but enough more than the 8t reusable threshold that being on a sub-GTO trajectory probably won't make enough of a difference. I wonder if using an extended fairing comes with much of a performance penalty? Edited February 11, 2021 by RCgothic Quote Link to comment Share on other sites More sharing options...

I think the extended mass inside that fairing would be the cause of that penalty. Quote Link to comment Share on other sites More sharing options...
