They should be relatively easy to swap out if necessary. Quote Link to comment Share on other sites More sharing options...

Not that weird. Obviously the hope was for SN8 to land, but it was definitely not expected to. SN9 tipping was not planned. Quote Link to comment Share on other sites More sharing options...

Yeah - the retaining strap seems to penetrate the metal. zoomed in on the lower right image - and that does not look up to spec. My thoughts; the actuators are probably gooned up as well. They probably need to redo all previous pressure testing - or just call it F Quote Link to comment Share on other sites More sharing options...

JoeSchmuckatelli Posted December 11, 2020 Share Posted December 11, 2020 Did not know that. Thanks. Still - when you shift that much weight and stop it abruptly, metal tends to deform and welds can fail. Quote Link to comment Share on other sites More sharing options...
sevenperforce Posted December 11, 2020 Share Posted December 11, 2020 Kicking around some ideas for the Starship landing legs...what do y'all think of this? The internal legs rotate out just like the ones on SN5, SN6, SN8, and so forth. However, they are solid pieces of metal; no crush cores or auto-leveling elements. Each leg is paired with an external fairing like the ones shown in the renders on the SpaceX website. They contain a hydraulic piston with an internal crush core, just like the ones on the Falcon 9 first stage. This means that the most sensitive element -- those hydraulic pistons with crush cores -- doesn't have to rotate. The load path is split -- half against the base of the skirt, and half through the piston and fairing to the upper skirt. The hydraulic pistons can provide a degree of auto-leveling. The rotating joint is completely separate from the piston and so they can both be serviced/swapped out independently. Depending on how much internal clearance you have, the legs could even be much farther out...not as far out as Falcon 9, of course, but significant nonetheless.

I like the design of that very much. You put a lot of thought into that. The only problem area I can see is how much of an uneven or unlevel surface they could be used on, especially the wider variant. If they are used for auto-levelling, wouldn't that put all the weight on one part of the foot? The foot itself needs to be able to rotate a little to allow for that. Maybe it's in the design but I missed it. EDIT: If you're adding external fairings anyway, how about a worm screw powered by an electric motor, like a glorified version of this?

RealKerbal3x Posted December 11, 2020 Share Posted December 11, 2020 Why am I noticing a curse of odd-numbered Starship prototypes? - Both Mk1 and SN1 popped -SN2 survived -SN3 popped -SN4 was destroyed by a GSE issue (not its fault, so it's not part of the curse) -SN5 flew, but its engine was on fire a bit -SN6 flew without any visible issues -SN7 was tested to destruction -SN8 flew almost perfectly -SN9 tipped over in the high bay It doesn't apply in all cases, but I can see a pattern emerging here Quote Link to comment Share on other sites More sharing options...

tater Posted December 11, 2020 Share Posted December 11, 2020 The only problem is the fact that anything external complicates TPS. Lunar Starship? That's fine, never does Earth EDL. Quote Link to comment Share on other sites More sharing options...

That's fine, never does Earth EDL. Anything external only complicates TPS if you have to have a seam in the TPS. My model doesn't need a seam in the TPS. Okay, here you go. I think this would actually work. The "high heel" or "stiletto" has no hydraulics in it; just a spring and a crush core. The pistons on the outer fairings have hydraulics and crush cores. The only actuated part in the "stiletto" is the hinge itself. The pistons do all the auto-leveling and the springs in the "high heel" will compensate automatically. This design can handle coming down on one leg, on two legs, lateral velocity -- anything. Everything that contacts the ground is safely tucked up inside the skirt until it needs to be deployed. No seam in the heat shield. Quote Link to comment Share on other sites More sharing options...
