This has been in the works for about 3 months now. Our first full documentary shoot. There is a lot of negativity in the comments from people who have not even watched the video yet. This channel is about being positive about engineering. Encouraging and inspiring the next generation of engineers. If you are looking for a channel that focuses on being negative and adds nothing to world, you have come to the wrong place. It's so much easier to point out what's hard, than using your brain to think of solutions. That's not what engineers do. We find problems, and then we find solutions. If you don't think a company that's trying to throw satellites into space, and has already built a 1/3rd prototype, isn't insanely cool. I don't know what to do for ye. That's badass. Whether they succeed or not is irrelevant. It's not your investment money they are using, chill out.

What an absurd comment.. “not your money”? You know how government funding works? “If you are looking for a channel that focuses on being negative and adds nothing to the world”.. yeah ok, because being realistic and tackling the ACTUAL ENGINEERING problems doesn’t add anything? I mean common, that’s the root of engineering: understanding the problems and working around them. But just ignoring the problems and dismissing them as negative and pointless (with a clear jab at a certain someone (because that’s positive)) is absurd. Strike one for not acknowledging any of this in your video (which ok, we all make mistakes), strike two for then childishly doubling down, when faced with a counter argument, instead of addressing it. The concept is awesome. Ignoring it’s flaws and dismissing them as pointless negativity is childish.

If you paid attention to his videos, you’d see where it would make more sense and be informative to display the relevant graphics than wave a flag with his face throughout the videos just to prove to everyone that he isn’t “super ugly”. That really floors me that you assumed that if people don't display their faces, they must be really ugly, much less wrote it for everyone to see.

If this works, it could be a good cost-saving measure for moving small amounts of cargo. If it doesn't, the technology and lessons learned could be used for other things in the future. Things don't always translate from paper to the real world so easily. So if the stuff fail (not saying it will) the data provided from the practical application could inform other engineers of potential issues with their designs so they can work on how solve them. Either way, it's nothing but a good thing someone is even trying this whether it works or not.

@gdutfulkbhh That's an interesting point. There would be a few ways for this. One would be using water as a counterweight. And dumping it it somewhat evenly during at least one turn of the rotor to not damage the vacuum chamber by the impact of the water. May not work, though. And dumping water into a vacuum chamber is less than ideal. Another one would be having a very fast mechanism that corrects the imbalance. Like some weights moving to the outside of the rotor, to where the capsule was. Has the problem that these objects are also accleerated, putting massive local stress on the arm and the bearings of the moving weights. The in my point of view most likely option seems counter-intuitive: Just accept the imbalance and build the structure to handle it. From a physics standpoint, the only thing changing is that the 100000 tons of force is not exerted to the aeroshell anymore, but to the bearings of the rotor. As long as they and the mouinting structure can hold these forces, an imbalanced rotor won't cause any damage. Or more as a joke: Just use a second capsule as a counterweight and add another launch door. This will also be launched at the same moment, but with Mach 6 straight into the ground. One may fill it with stuff one really wants to get rid of, nuclear waste may be a bad idea, though.

A considerable waste of energy will come from whatever you do with the counterweight that you have to jettison at the same moment that you launch your spacecraft. (If you don’t do that, your rotor arm will destroy itself and the facility.) If you can recover the energy imparted to the counterweight, it would be worth doing. I still think this won’t progress beyond hosing down the investors, though.

I do not think this is impossible, but I'm curious how they are going to deal with all those problems - one in particular I never heard answered is that g-loading is one thing, especially since g's are going to increase gradually as it spins up, but at the moment of launch payload would go from 10 000g to ~0g of ballistic trajectory in like a couple milliseconds. Wouldn't everything that is compressed like that just spring back up and destroy itself? That's something a centrifuge can't show you, as it will also have to spin down over time.

I’m not physicist but I don’t imagine the removal of g forces acts the same way as the addition of g forces. I.e the material wouldn’t violently spring back, just naturally adjust in the absence of 10,000 g.

nice idea to launch a second vehicle 180 degrees after the first, has anyone considered (modeled) the velocity of projectile #1 vs the velocity of projectile #2 that will be travelling in the turbulence or even partial vacuum created by projectile #1?

Can someone explain to me ..... what should be the payload of that rocket , that can handle 10,000g ! I mean .... doesn't the things inside the rocket need to be exceptionally strong too ... just like the tether ? Because that means that the things inside it ,will be also 10,000 times heavier than their weight on the surface of the earth right? would that turn everything inside into a blended soup of things ? how does that works?🤯🤯🤯

I wonder if they have taken into account Earth’s rotation. The tether is basically a gyroscope willing to maintain its spinning axis. As Earth rotates, there will be an increased pressure on the bearing.

This is less of a problem for launches to orbits of (near-)equatorial inclination. I'm sure they've thought about it and my guess is the effect is insignificant even in the worst case (polar orbit launches). Of course without doing the math my intuition can be very wrong when dealing with such extreme speeds.

Would love seeing this in combination with something like a space hook, so no rocket fuel or stages are spent at all. The boogeyman of our getting trapped on our planet if too much debris fills low orbit gets even scarier the more companies get in on the satellite game, so single-stage (or as the case may be zero-stage) to orbit capabilities are always looking attractive to me.

Very nice video description and engineering application. Amazing solutions and innovations from smart engineers thinking outside the box. Very refreshing and inspiring. I'd be curious to know with current's material technology/properties, what the max teeter mass, rpm, and spin radius could be achieved. Also, at these momentum levels, is Spinlaunch concerned with any precession effects due to earth's rotation at the launch location site? I guess this is why one of the demo site had the spinning case tilted, to be aligned with earth's axis of rotation?

Any time I hear anything about SpinLaunch, I’m amazed it got this far, with all it’s shortcomings. 1. You can’t use it on anything living. 2. Anything launched has to be able to handle the high G forces and sudden change in forces, at launch. That means satellites have to be made extremely robust. …like building an airplane to the specifications of a battleship… 3. The launch vehicle will be extremely limiting, since it’s not scalable. If it doesn’t fit the launcher, it doesn’t fly. 4. There is no margin for error and no abort mode. If something breaks before launch velocity, you’d better pray it holds together long enough to stop the spin. If not, you get to watch the whole launcher explode in spectacular fashion. Those are just the most obvious problems…

This all makes perfect sense but what I can’t quite figure out right now is spinning something that weighs that much in a vacuum or otherwise and then instantly that that balance is gone so after the rocket is tossed how does it rebalance itself before it shakes itself to pieces because you can’t stop something with that much torque instantly.

@Obi-Wan Kenobi For sure, the cable would have to hold its own weight (or twice that?) along with all the cargo. But if we had that, I don't expect keeping it balanced would be all that difficult, comparatively speaking. You've got hundreds or millions of tons of cable and counterweight, and it's obviously going to have to be flexible enough for the counterweight to move around in its orbit. I think if you can keep it stable resonance-wise, balancing the counterweight at the end in the right orbit will probably be no harder. Check out a couple sci-fi novels, "Dream Park" (Niven) where a sub-plot is that they're building a beanstalk on Mars so when it goes disastrously wrong it doesn't wipe out all life on Earth. Or better, "The Web Between the Worlds", by Sheffield, which is basically a murder mystery set in a solar system full of pinwheels, beanstalks, etc. Both novels are lots of fun. I have no idea how realistic they are.

If you make the launch exit duct 5 times longer it would give you 5 times more flexible delay to seal back the chamber at lower cost, and you could use more single action doors, so some doors only opens and others only close...

The same centrifugal force which applies to the payload also applies to the counterweight. So you need a device which creates the the same amount of force just in the opposite direction to pull the counterweight to the center of rotation. But if you have a device which could create that amount of force to pull counterweight you could also use it directly to pull the payload (which has the same mass as the counterweight) into the direction you want to shoot it and the whole spinning wheel would be obsolete...

@18:54 When the secondary door closes, it appears to be a pressurized fabric, very much like a car airbag, which are also super fast in deployment. They would also release minimal air into the system. I guess once sealed, then the regular door can be more slowly slid into place. Interesting workaround for this problem.

What an fascinating concept. It reminds me of a TED talk on launching satellites from a gas gun - the part that really stuck out to me there is that it's remarkably easy to build high g tolerant electronics. In fact that shouldn't be a surprise as artillery shells have had electronics since WWII proximity fuses and modern surface mount electronis should be a lot more high g tolerant than the WW2 era vacuum tubes equivalents. E.g. an M982 Excalibur round has GPS, INS and fins that deploy and steer for a glide. The gas gun guys reckoned you only needed some epoxy on the sharp corners of surface mounted components, i.e. it was a problem with well known solutions.

You can increase various strengths in carbon fiber composites by adding in carbonized cellulose nanocrystals into the epoxy resin. CNC's are relatively easy and inexpensive to make in bulk, (and they have graphene like qualities when graphitized and carbon nanotube like properties when carbonized). The carbonization part is more energy intensive, but building vacuum insulated Solar concentrator ovens or the like, seems like it would be a cake walk for this team. Btw, a tip for getting high quality CNC material is to start off with a good raw material to begin with that is high in the crystalline cellulose. A lot of industry uses waste wood pulp which has low levels of this. But on the other hand, a lot of natural textile plant fibers we already use, such as flax, jute, hemp, cotton, etc are already pretty high in crystalline cellulose--usually anywhere from around 60 to 70 or so percent of total material. And you certainly can use waste sources of these. Oh, and since these materials are more thermally conductive than regular carbon and graphites, it would help with any potential overheating issues some by more rapidly dissipating and spreading out heat energy in the structure (if say the system malfunctioned and doors didn't close fast enough or what not).

I will admit, this video answered my questions about the door mechanism (which was only a membrane before). Many other aspects of the system are clearly feasible, such as the low atmosphere vessel, and energy requirements. However, I do not feel like the enough information was given on how the vehicle/payload would deal with high shock events, and they are clearly hiding their release mechanism design. And yes, that release mechanism will be proprietary, but it should be the biggest concern for potential investors, as the loads it must endure are very high and it must release the vehicle in nearly an instant without imparting any significant torque. I still don't believe the project can scale up, but I will be happy to be proven wrong, if they can pull it off.

No significant torque? Depends how you define significant, I guess. The object at release time has angular momentum of 450 RPM. If the release mechanism doesn't impart an _enormous_ torque as it releases, the rocket will tumble at 450 RPM, or 7.5 end-over-end rotations per second. So, yeah. Within a fraction of a second at launch time, it will have to go from 450 RPM to zero angular momentum, somehow. Stopping something from spinning 450 RPM isn't that bad ... but this has to happen in a very short span of time and distance.

@Logarithm If you're spinning up the small rocket to mach 6 and getting it to 72 km you're already 72% of the way to space and only using $500k to get there the rocket would have to be tiny even to get something to arount 160 km. The cost of using a 747 to get to only 15% of the way and dropping the rocket moving at only around 490 knots (.89 mach) and accelerating from there is much more expensive. For refrence the speed needed for a stable low earth orbit is mach 20. The 747's hourly operating cost is around $26k per hour (source aircraftcostcalculator.com) plus up front costs for the plane plus launch vehicle costs. Spin launch would be astronomically cheaper due to minimal launch vehicle cost and a few million dollars for a mach 6 vaccumized centrifuge. Edit: virgin orbit's launcher one is planned to be $12 million dollars per launch. The cost of the centrifuge will likely be around that as an up front cost plus $500k per spin. The boeing 747 costs $20 million plus the 12 for launcher one.

This is kind of like the spinning hubs put in different areas of space and you throw a payload from one to the other until it reaches its destination.

Had this idea a couple of years ago ( except with an elevator mechanism, and the projectile launched in a vertical vacuum tube). Wonder if launching from a very tall mountain and spinning up the projectile like a football on launch would help with the initial shock of exiting the vacuum. You can see the rocket wobbling and losing tons of inertia as soon as it leaves the vacuum chamber.

Part of the problem is the speed they are launching at, as in it is too low. That wobbly launch was performed very close to mach 1, and transonic forces are notorious for creating these sort of unstable aerodynamic forces. The issue is somewhat self correcting due to the aerodynamic profile of the vessel, only resulting in a relatively minor loss of efficiency at initial launch.

I'm sure many people have mentioned this - but I have to say that the extreme centripetal accelerations during the spin-up phase are probably the most concerning issue with this approach. I have worked on projects that involved similar levels of acceleration (and higher), and while overcoming the effects of those levels of acceleration is definitely possible, it also increases the costs necessary to achieve reliable results. In other words, payloads will cost more because they will require more engineering work to ensure they survive. HARP was mentioned, and is definitely a good comparison point (it had somewhat similar accelerations, albeit for much shorter durations), but what was glossed over is that HARP required a multitude of trial and error to get payloads that survived most of the time (hundreds of tries with many configuration variations), and even then it was incredibly difficult to make the "large" 16 inch projectiles survive. In fact I'm not sure that any of their projectiles that achieved those altitude records even were in the 16 inch class at all (I believe the highest flying projectiles were all saboted 7-8 inch or smaller projectiles). Additionally, those high fliers had solid rocket motors in them to boost their performance considerably. The take-aways from HARP are that high-G is actually incredibly difficult when you are dealing with large projectiles (small objects at high-G are the easiest), and making things survive, while possible, takes a good deal of time and effort and hence money. SpinLaunch is definitely an interesting idea, but for most payload applications I tend to believe that those accelerations will be a deal breaker. Especially when one considers that the actual cost of re-usable rockets (not expended rockets as were exclusively talked about in terms of pricing) is already around the same as what they are trying to achieve with this system. Using it as a mass driver for insensitive/robust payloads seems like the most likely application, but if they aren't to market very soon, I expect they won't get very far with any kind of payload market. Also, I noticed that you conveniently ignored the re-use aspect of SpaceX rockets and inflated the cost of launch with them beyond a fair value. The $67-million price tag is for a new rocket at recently updated pricing, and the stated maximum payload (which is fair because you used the stated maximum estimate from SpinLaunch) is 22800 kg, or about $2940/kg when expended. But SpaceX launches re-used Falcon 9s far more often than new ones, which most guess at around $50-55 million per launch. Furthermore, SpaceX likes to recover their first stages, so they probably charge less than that if the payload stays below the re-use maximum of 16700 kg. Being generous, we can stay with the $2900/kg, though based on past statements it is probably closer to around $2500/kg for paying customers on re-use launches. In any case, that is pretty darn close to the same price/kg as SpinLaunch is hoping to achieve, and probably beats it - especially when SpaceX is its own customer. And that's just with Falcon 9. Falcon Heavy is cheaper yet, and Starship (if it works anywhere near as well as expected) will blow everything else out of the water. Even at say $20-million per launch (10 times as much as Elon is hoping for) Starship would still be around $200/kg. Comparing this to Starship is a fair comparison since Starship is likely to be operational before SpinLaunch. Don't get me wrong - I do think SpinLaunch is a cool idea, just as HARP was a cool idea in its day, but ultimately I don't think it solves the problem in a way that is ground-breaking enough to be worth it.

While that door was fast, as you note, it has significant bounce. It reminds me of firearm bolts that must close and lock into battery in a very short amount of time.

For example a sealing system that sits above the final position that captures, seals, moves with and helps decelerate the door as it settles into its final and locked position. Making the door as light as possible helps with acceleration and deceleration.

This type of launch system was something that was in my mind since I was a 5th grader. I drew designs like these on paper with the dream to reduce the cost of launches. Another idea was basically a longer more powerful rail-gun. When I reached college, I did some calculations and came to a conclusion that it is not as feasible as I once thought it would be, and dropped that idea. Now, I am pleasantly surprised with someone attempting to make it happen against all odds & trying to push engineering to the limits! Only thing that didn't make sense was the cost per launch. How is this still more costly than the Falcon Heavy? This system cannot carry delicate stuff but the thing is If we are going to be an interplanetary civilization, we would need something to carry large amount of "dumb payload" like fuel, water, food and even construction material. But, I really thought the cost would be significantly lower as otherwise this thing is not really useful for those kinda dumb payload if Falcon heavy is able to carry it cheaper, thus rendering this only useful to launch super-hardened satellites that require specific orbits. But still, great to see someone try! Regardless of if this succeeds or not, it will be a great experiment to see. And, congrats on your first full documentary, it was very good, and kept my attention till the end. Way better than most Discovery documentaries these days.

he completely explains aspects like the required strength of the tether and the absurd speed that this thing would need to spin up to, but hasn't mentioned anything about extreme precision you would need to release the payload with. He said the arm radius is 45 meters long. 2pir gives us the circumference of the loop the payload would be making. About 283 meters. Mach 6 is about 2000 meters per second 2000/283=about 7 rotations per second 7 rotations=about 2500 degrees per second 1 degree every 23 milliseconds They probably only have a tolerance of plus or minus a tenth degree because the arm is so long and one tenth of a degree is about 8 cm so if they are more than 3 milliseconds off (at best), the payload would be destroyed along with the vacuum chamber and there will probably some sort of implosion due to the pressure difference If you have a problem with my math and estimates, do it yourself moron. The actual precision required is likely even higher because of the long cylindrical exit chamber that the payload has to fly through without hitting the walls or the sides of the doors. Not to mention that the doors also have to act with the same insane precision This, while not impossible, seems like a major challenge that wasn't even mentioned in this video!!!!! which makes me doubt weather real engineering is being critical and inquisitive here or just sucking up to them like a fanboy.

An average communication satellite weighs in at about 3500 Kg. It is designed to handle about 5G during transit. At the 10.000G they're talking about, the satellite will be pressed into the sidewall of the rocket with a force equivalent of 35.000.000 Kg. Let me point out that that's the weight of 590 Abrams tanks on earth. Or over 20.000 cars. All pushing on a satellite filled with sensitive electronics, batteries, fragile antennae dishes and solar panels. A single 10 gram UTP cable inside that thing will have 100 kg's pulling on it. A loaded circuit board would have 20.000 kg's pulling on it. The battery, at 350Kg, makes up 10% of the total mass of the satellite. It will be pulled with a force over 3.000.000 kg. Even if the battery could survive that, which it can't, you can't just hold that in place with some screws, man! It's gonna tear right through whatever structure it's attached to inside that satellite. They seem to shrug it all off, as if it's already solved and it's really no big deal. You just need to "think differently". Just corrugate some aluminum, fold down the reaction wheel, and add some epoxy here and there. Done. No need to overthink, just have faith.

Even simpler question – how do they mechanically decouple a payload at 10.000G? Moreover, decouple at precise timing, because if the timing is off the consequence is a catastrophic explosion. 35K tons decoupling at Mach 6.5, that's 85626520 kinetic megajoules at ground level.

For anyone who has heard of the Sprint anti-ICBM missile from the 1970's, this is completely feasible to make function as intended, albeit quite difficult. For anyone who doesn't know, the Sprint was a high velocity direct interception missile that would reach Mach 10 within 5 seconds of launch from the ground, going through a similar flight regime in many aspects to what spin-launch's vehicle would have to endure. On top of that, the acceleration of the vehicle during the initial phase of a sprint launch is significantly higher than what the spin-launch would impart on a launch vehicle. Once again with that being said, what they are trying to do is incredibly difficult (some might even say a bit crazy), but the system truly does seem to be possible and I hope to see them achieve a successful orbital launch in the near future.

Can you explain at what angle the launches occur? Rocket launches look vertical whereas the spin launches appear be at an incident angle to the surface of the earth. The expendable counter mass must be somewhere close to the mass of the projectile. That seems like an enormous amount of energy to release. Maybe if they could launch two satellites at the same time, if the bearings can truly endure a half rotation in an unbalanced state.......Amazing rethink of the trebuchet!

As I understand it, they can aim the exit, but it should be mostly upward to get through the thickest part of the atmosphere as quickly as possible.
