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.

@Jason Ward You really assumed that he was “super ugly because he just spoke”? Really? What kind of immature, petty mind comes up with that? We hear him speak because he’s always displaying awesome video and/or excellent graphics that are integral to the video's content. 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.

The g-force involved in these - 10,000 g's - was dealt with back in world war II with proximity fuses in artillery shells which are probably pretty similar being shot out of a 5 inch barrel from 0 to several thousand feet per second is pretty much the same thing they're doing hence the 10,000g-force but was dealt with a long time ago by much less computationally aided people It's amazing what we used to do with just a slide rule looking at this up to and including put a man on the moon absolutely amazing

So I guess this would be the "David" to "Falcon Heavy" as Goliath... I recall seeing this essential format in Popular Mechanics back in the late 1950's/early 60's - they suggested it could form the basis of a military field gun as launching satellites wasn't a big thing back then.

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.

Despite the fact it can't launch massive payloads, this system would still be insanely useful for countless things since right now even small payloads require big and expensive rockets.

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.

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? I think if that were modeled properly, you may find a collision in every case.

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?🤯🤯🤯

@TheRainHarvester I'm not sure what you're answering with that one word as I replied several times in this thread, but passengers really are the least of our worries with regard to space travel in the next few decades. Any form of infrastructure in space is going to be *far* more cargo-centric than human-centric. If you can lift everything with a kinetic system like SpinLaunch it's pretty trivial to send a pod with people up after, and probably far more cost effective than developing a space elevator would be.

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?

Imagine launching an ordinary missile from one of these. You would be able to extend the range of your current arsenal by thousands of miles. You could spin launch a surface to surface missile and not worry about adding fuel because once the missile leaves the atmosphere the engines don't have to push against air or humidity, thus extending the amount of time the engine runs and adding to it's range. Honestly I think since this is being tested next door to White Sands Missile Range I don't see why it couldn't happen.

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.

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.

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 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. This could do that with a sending station and a single stage rocket to slow it down at the other end. Just not seeing how this will work out in our atmosphere and be competitive in the market.

Could you have some type of mechanical latch that catch the "exit door", preventing it to "settle" when it closes. Or will the residiual vacuum in the chamber make sure that it remains closed instantly?
Richard Casto
Richard Casto Mês atrás
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. I think there is a lot of room for optimization of that inner door. 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.

I really liked this video but noticed that a discussion of failure modes and safety was conspicuously absent. What happens when their Mach 6 projectile fails to release at the right point? What happens if the airlock doors malfunction? How is safety of ground crew assured and damage to superstructure minimised? The concept definitely has legs but I worry that a catastrophic failure early on might spook investors.

I’m surprised that they didn’t just call a shipyard for the vacuum chamber. The double bottom tanks on ships are built to withstand more than 1 atm of pressure because of hydrostatic loads, and shipyards will have the experience, equipment, and workforce to easily and cheaply produce something like that.

@Lakin Moser Vacuum is the difference between outside pressure and inside pressure. So technically, a submarine would be a vac chamber because it’s lower than the local exterior pressure. Outside in our atmosphere, anything less than 1 bar is considered a vacuum. Yes, the weight of the atmosphere is putting pressure on the outside of the chamber walls. You’re description isn’t wrong. Neither was mine.

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).

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.

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.

That problem of eliminating the weight of the rocket fuel to make launching payloads into space I have been thinking about for quite a while now. And I came up with the idea of making a several mile long electro- magnetic rail inside a large vacuum tube. That would get a payload going at supersonic speed before it even leaves the ground. .And have the end of the rail gradually head vertically.

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.

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.

I'm wondering whether the 'spin launch' concept ends up making good use of the 'launch from a mountain top' concept (a.k.a. raising the launch altitude) in order to minimize the amount of time spent in the higher density / pressure lower altitudes. (It's never been significant for 'traditional' rocketry, but perhaps it becomes more significant when there's no thrust provided for the first few dozen kilometers)

If I remember correctly their launch facility is in NM which already sits at an altitude of 3-6k feet above MSL, which would be about 2-3psi lower pressure than at sea level and if they built it on top of a 14000 foot peak in CO that would lower the pressure an additional 4psi for a total of 6-8 psi lower than MSL so mathematically it might make a difference. However traveling a their projected Mach 6 launch speed and ignoring velocity loss for a moment and assuming that the launch site is at 5k ft MSL the projectile would traverse that difference in altitude in about a second (Mach 6 = 6750ft/sec) going straight up (I assume vertical launch because with system like this you aren't gaining velocity as you climb unlike a traditional rocket that has to reach escape velocity and therefore has to angle its trajectory to gain enough distance to accelerate up to speed, but I'm not a rocket surgeon so not sure about my SWAG there). So again maybe it makes a small difference in efficiency to launch from a higher alt. but there is also the feasibility issue of trying to build something on top of a mtn and I would hazard a guess that the gains from launching at alt. compared to the cost of trying to build and operate a facility at alt. make the idea impractical, we're talking marginal gains for exponentially higher costs.

How does it handle the sudden severe imbalance in the rotating arm when the vehicle is released? Not to mention the shock of the atmosphere rushing in to disturb things even more. I don't understand how this would not tear itself apart. Martin Savage used to talk about building a mass driver on Kilimanjaro. Something like this on Kilimanjaro would already be past half of the atmosphere. Much less initial velocity would be required. Interesting concept but hard to imagine how it will ever be used in practice. Especially with the cost of payload going down with Starship when it comes online.
