Here is my idea of a way of landing the SpaceX Superheavy booster without legs. The second part is a concept for the iris system that rotates 2 rings in a way that a booster landing can have a more wider landing area and a larger margin of error. In a future video I will be updating the video with a more simplified launch tower and improved stronger grid fins.
Extra points for that crew access deployment surprise.
the iris is smart. wonder will it be structurally strong enough tho
Rocket without Fuel is light af
@@SixonQQ Relative to the wet mass, it still weighs an estimated 300 tonnes
@@heatherlee4366 Wikipedia estimates dry mass of the first stage at 180t en.wikipedia.org/wiki/SpaceX_Starship
Done some calculation: when the booster falls at 15m/s the system needs to dampen 20 Megajoule of energy. When the shock absorber is 10m long it needs to provide 2 Meganewton or 204 tons of breaking force.
@@quazar5017 would the booster not be able to slow down further than 15m/s ??
@@Chapter3Fan sn10 landed at 10m/s and super heavy will be able to hover so 15m/s is a bit much but over engineering the tower to take a load like that couldn't hurt
this might be the best animation i have seen yet
agreed
I'll 3rd that
The Iris is genius. I would’ve never come up with that.
The whole idea of even catching it is insane, can't wait to see it!
This is the most credible looking visualisation of the catching method I've seen!
Elon did say open top so I think this is the most accurate so far
yes but for stability you have to add fins and fins would be a problem means circular catch arm is not possible
@@melonmusk1342 the falcon 9 does not have fins. I think they can use the engine gimballing to keep it on course. But we don't know. Could have fins or not.
@@jochemlaurenssen9440 Isn’t he talking about grid fins? Because I’m pretty sure the Falcon 9 has grid fins right?
@@captainjackpugh6050 yeah. The F9 uses only grid fins and can land successfully. That means they can use a system like IRIS to hold the Superheavy.
@@melonmusk1342 Super Heavy will have grid fins.... as seen in the video
That's a novel idea, for sure. I have thought as well that there has to be some room for error in the placement of the booster as it comes in. You can't guarantee it's going to be exactly where you want it, and this is a very interesting way of accommodating that situation. Seems a little complicated with a lot of moving parts, but elegant nonetheless.
Yeah. The fewer points of failure the better. Be interesting to see what SpaceX come up with.
I'm not sure it really is super complicated though. It appears to effectively be just 3 modified concentric circles.
@@bob38028
Good point. The motors in the outer circle and middle circle will need some serious torque to center the booster stage for lifting by the crane though.
@@topsecret1837 Indeed, I bet Tesla's got a few tricks up it's sleeve
@@bob38028
That I have little doubt. Not the first time SpaceX borrowed from its sister company.
At this point SpaceX is just making vague ideas and let the community came up with the best invention. lol
Elon: I don't know how to catch Super Heavy.
Also Elon: Let's post something on twitter and learn all possible approaches for free
For realist load-bearing capacity:
Make the circles into taller cylinders with light-weight fin/spokes radiating to the next larger bearing.
Or, change the transition between bearings/circles into tilted cones.
Use much wider-spaced load bearing structures at the periphery so all possible loads stay within the footprint.
Iris idea is genius
Awesome Idea, the iris is such a simple idea that is so impressive.
Heavily underrated
Very interesting powered landing concept!
Cool concept, but i think it's too many moving parts which can make major failure and also it wolud be really expensive to repair. The steel string catcher concept is maybe more realistic coz of its simplicity.
it isnt simple, and would put a lot more stress on a smaller area. it would also be dangerous to repair. look at Arecibo
even if they can use best materials probably first attemp will destroy whole platform.
@@Trim11 nope
Gear driven systems can be very reliable.
@@MonsieurDijon
That’s a false analogy. Arecibo was far more complicated than this.
Whoever thought of this smokes weed for sure. Genius !
Great animation! Thx a million for sharing.
This animation is on 🔥 👌 😎 . Good job...
Fascinating Design!
Amazing concept
VERY nice work!👍
Very clever, best one I’ve seen yet!
That is amazing! So smart!
This tower is awsome!
Really really cool!
Great concept 👍👍
Good concept!
Wait, wait, it can huh. wow wow wow.
This is great! and elegant too
Fantastic job 👏
Best I've seen yet!
Awesome work. Love your concept.... high level of ingenuity ❤🚀
Kick-ass Idea
Awesome news. Go SpaceX 👍‼️
Amazing stuff my friend
this is sick
Best. Concept. Ever.
that’s so cool!
As an alternative, a much lighter ring truss structure could be suspended by six or more *pairs* of cables that steer the ring to stay centered around the ship hull, even as it drops through. The upper ring surface would be resilient to accommodate the collision of the grid fins with the ring mass.
The horizontally oriented cables would primarily steer the ring while the sloped cables would support the load. The sloped cables could played-out as the ship pulls down the ring, decelerating any residual velocity. The cable tensioning system would assure that the cables winches give at a setpoint limit, rather than self destruct.
The imagination has no limit, transforming it into reality quite another thing
Try space engineers, it's not perfect physics but close enough.
Pretty cool 👍
That’s actually clever!
This is amazing
Fascinating design. And great work with the animation.
BTW, "off-center" not "of center." Took me a second to figure out what you were trying to say in that slide.
Bro Nice work
I like how only the top most part acts like a motion crane and not the entire upper half of the structure.
Incredible
Good idea and excellent simulation! It may be difficult for the IRIS system to run nimbly while enduring high heat and turbulence from the incoming booster tho.
Yeah, that's a good idea!!
Best concept
Brilliant!
now i get it, super cool
I thought this is good, awesome
That is dope
My new video is out now with a more detailed concept. Let me know what you think. You can watch it here: ua-cam.com/video/etm5BgSsZbE/v-deo.html
That was genius!
The iris seems to contain to many moving parts and structural geometries that would be sensitive to misalignment imo but the concept of moving the central ring looks really promising. A sturdier design would be two conenctric rings, the large one being a sun gear rotating between two concrete pillars connected to the central ring by means of two forged alloyed steel beams running tangential to the central ring as a moving linear gantry, essentially an elevated railway turntable with a hole in the middle.
Yes that could work as well. Good idea.
@@jochemlaurenssen9440 Yes, your design most likely works equally as well with the correct design and a bit of FEM, I just thought of the old saying from Lotus "Simplify and add lightness". By utilising standardised industry "Lego-bricks" it's simple and fast to produce and it's the lightest simple solution i could think of
why the ramp if you are hoisting both parts anyhow?
The rocket can land on its own feet, all needed is arms to grab the top to keep it completely vertical, the position it lands in, they can be quite long, doesn’t need to support much.
Good Idea
This is really innovation. Unlike SpaceX's competitors Boeing, Lockheed and the ineffable Blue Origin, Elon keeps on surprising us with visionary concepts just right out of Sci-Fi.
The only downside to the iris that I can see is the size and speed of actuation. You wouldn't have much time before the sensors predict the landing trajectory with some decent certainty and the booster actually approaching, and those iris rings would be *large* and probably heavy to endure the repeated landing sequence. Spinning them up will take some time and I'm not entirely convinced it's gonna be fast enough simply due to inertia (both when speeding and and when slowing down).
Considering how fast starship is able to move its own fins using electric motors, I’m fairly sure they could do the same with a ring system like this using said electric motors.
@@topsecret1837 Idk how heavy the fins are, but it seems to me these iris rings would be much more massive and may require even higher speeds depending on reliability of the landing prediction system. I mean, it would be an elegant solution, so I hope it's possible. Quite visually pleasing as well.
Great work❤️ plz make one based on scissor concept🙏
Awesome
I like the idea but I don’t know if the iris will be able to rotate quickly enough to get a bullseye capture
Great!!
I like it.
I'm have been sitting here for months thinking about different ways to solve this riddle. There is a part of me that wants to call you names and give you the keyboard mafia response but this is fucking genius. Bravo
That's clever..
I wonder how they will stabilise stacking starship onto a booster under a bit of wind
Iris design is great 🏆
We will see whether they can make work for more than one landing 🤔°•.
It's smart
How about a closing iris like the portals from Alien (#1)?
no, I think everybody's overestimating how much strength there is in the grid fin situation. The grabber will have to be much closer to the hull.
Your right. This is the grid fin design as provided by the spacex animations. I am currently working on a stronger grid fin design that can take the load of the booster.
@@jochemlaurenssen9440 the more significant factor is the fact that this fin is cantilevered off the side of a thin walled can.
@@weatheranddarkness Yes there definitely has to be some reinforcement on the inside. Although I think the booster will be more rugged than starship, because it operates mostly in the earths atmosphere and carries more weight in the form of engines, but does not need a heat shield.
@@weatheranddarkness "The can" does not experience a cantilever load. Think of the grid fins as landing legs. Landing legs distribute the load evenly so that the can experiences a compression load. Grid fins distribute the load the same only the can experiences a tension load. However, your point does illustrate that each fin catchment mechanism may need its own shock absorption, so three independent shock systems, just like landing legs have. This distributes the load on initial impact, (because it doesn't hit perfectly square) so that an over load on the can does not occur. I don't know. Not fair to directly compare fin load to landing leg load. They could move the fin catchments as fast as the rocket is moving, engage all three and then slow them down.
@@weatheranddarkness I think it would be relatively easy if it could land squarely. But it can't. If you draw a center line right down the booster, the degree that it is not true to that line can create huge loads. The whole thing is like a pendulum, the whole booster is a lever arm. Especially with the engine weight at the bottom. What would landing the booster be like on legs if there was no engine weight at the bottom and all the engine weight at the top? Its these sorts of loads that make the problem hard. Not associated with the cantilever of the fins though. Just loads in all the wrong places.
I'm sure they can control roll well enough to not need a ring. Should just need two beams. The beams length take care of all misalignment in x axis, the beams being able to move on the y axis takes care of misalignment in other direction. If they can't control roll then won't work but I'd be surprised if they can't. I think the tolerance for roll would be large enough, depends on cantilever load limit of fins. ... Awesome design and rendering.
Im happy!)
Gran captura ❕👩🚀
This is pretty cool, not sure the Iris is the best design / simplest design but the rest of the setup looks good.
That said, I don't think having the Starship go up the ramp is either needed or a good idea. A tilting / balancing platform is a lot of complexity and for what? A raise in elevation right before its about to be picked up by a crane?
It's not needed at all, just have the Starship travel on flat ground to the base of the tower and then have the crane lift it the full distance. Simpler / less cost in concrete and moving platform.
Jochem - looks like a terrific preliminary design but with some changes required since the date of your publication. Of course, the most important change is that Musk now plans to catch the Starship as well as the Booster. No problem there because your design can work with both. Last week Musk said that the Starship (Booster/Starship) would have to have assistive support at launch to relieve the pressure of the Starship on the Booster. This could also be done using your device to hold the Starship during launch as well the whole mating process. Musk may have something like this in mind because he has one nosecone floating around with a flat top on it. Nothing I know yet has been said what that will be used for. Myself, I think you catch the Starship at the top or below the top fins. Below the fins I would use a segmented "ring" that lays flat against the circumference hinged on struts below the ring. Thus it would fold out and down as the ring is opened. You could cover about 60% of the rocket without attachment points on the insulation tiles. I look forward to what you probably already have in mind.
Interesting.
Mast video ❤️
Dude this is bad ass! But the catch system might be too elaborate. I think elon would want more of a simpler catch because of how much it would cost if a super heavy crashed into the rings.
what part of richest man in the world dont you understand lol :P (jokes) he can build 30 towers all good lets go!! lol...
هو مين اللى حا يلحق يلف الماسك .. لكى يمسك بالصاروخ
How about instead of catching the vehicle, letting it land on a air suspended ring table.
I hope it all works and they are prepared when something breaks
Neat
Why does this look like a scene from the Thunderbirds?
You - absolutely- MUST add the music of the "Thunderbirds" to this video !!!
Wait, so this method is able to adjust to any point within the diameter of the outer ring?
Yes it can
@@jochemlaurenssen9440 Have spacrX seen this? This is brilliant and heck, it looks cool
Airplanes can do auto-landing with differential GPS. So can rocket
Wow!!!
I like😌
Super heavy lift cranes rock. I bet .01 bitcoin that SpaceX will build the 1st 500m tall lifting crane : D
Kool ! What software do you use to do this pls ?
I use blender.
It’s quicker than oil change at Jiffy lobe.
Wow !!!!!!!!
Really nice animation. Nice addition of the crew access arm.
elon: you’re hired.
Il believe it when I see it.
you are smart
Vai sonhando que isso vai acontecer. Talvez no ano 3.000 DC.
