A local amusement park organises excursions for year 12 physics students. Lets just say it was one of the more enjoyable excursions I've had and it was definitely an experience of physics. Only a couple of demonstrations of biology by some people on the rides I went on :).
This kind of technological 'behind the scenes' videos are great! More please. Also, you can still tell how dangerous something is by how much Anni screams. Fun!
I love y’all so much and I don’t love anyone. Seriously it’s the personality. The videos. The lifestyle. Everything about you 2. It’s perfect. My top 5 you tubers ever
the linear motor is quite clever when it first moves up halfway and then continues through the rest of the track on the next "uphill". The power is perhaps more evenly distributed. If it would go all the way to the top on the first try, it would need a larger energy peak at the start. Now when it passes the linear accelerator 3 times, that total needed energy can be split into 3 sections :) less electrical peak demand on the electrical grid :)
It looks like they use it as a brake too, at the end of the ride. Unclear if they're actively applying a reverse polarity drive or just dissipating it into resistors.
@@AndrewZonenberg pretty sure they are at least doing some active switching (you can hear it when it slows down). It's not a passive brake. Not sure whether they are backfeeding into the electricity grid or dissipating it though.
They simplified the design to handle peak power, but at the same time passengers experience the for and back movement as part of the ride experience; very good way in my opinion.
@@pflaffik Yeah that sounds about right, 920rpm / 60 = 15,33 rotations per second, 30 frames per second meaning thats 15,33/30 frames = 0,511 rotation per frame.. 0,511 times 360 = 183,96 degrees. Yes i had to calculate if myself to see if your answer was correct (And if my brain still was capable of understanding this method of calculating, thank you for challenging my brain and tickling its hunger for knowledge :D )
The flywheel coaster is made by Zamperla, an Italian rides company known more for their non coaster rides. The second LSM coaster is make by Premier Rides, a US company that makes launch coasters. The first installation was made as a custom ride for Six Flags Discovery Kingdom which had a limited budget, space and height restrictions. There have since been around 10 copies made.
Really cool video guys. That POV footage of the second rollercoaster was crazy, I actually felt like I was on the ride, but without the G's, LOL 😂😂 I actually got a little bit scared, I'm afraid of heights.
Well I know where I'm going whenever I get a chance to visit Finland. The use of that linear motor in that second coaster is really cool and switching direction twice looked like it would be fun. I like how it went relatively slow around the roll before the drop. I'm a fan of these compact coasters. If you wanted to make more videos about other rides I would love to watch it.
That was awesome. I like the diversity you guys do in terms of content. That was really interesting to see and also fun to watch because it's in your part of the world where I am not at. Keep it up guys you are awesome
Yeah probably burns it all up in a massive resistor.. but yes, I too would like to know how much energy it has to dissapate to stop! Would be cool if it collected it all in a big capacitor and saved it for the next launch!
@@clayboi6939 I dont think it can be compared to a diesel electric locomotive that dissipated electric braking energy to a mesh resistor in the roof. This one should work more like the braking feature of some newer brushless powertools, the electronic controller activates coils in front of the magnet, thus the brake consumes electricity instead of generating it and then no need for a superhot dangerous resistor mesh.
@@clayboi6939 or perhaps sent the power to the flywheel or if there was a second linear coaster that was staged to start right as this one was stopping. then as the 2nd one was stopping this one launches. kind of sharing power with only needing to consume what is lost between the two. I would imagine it could possibly recover 50%
Linear launch coasters are slick. Right in my backyard here in Cincinnati, OH the first LIM (linear induction motor) launched rollercoaster in the world was built at King's Island amusement park back in 1996. They also built an identical one at King's Dominion. It was originally named The Outer Limits: Flight of Fear after the TV show but was later renamed to just Flight of Fear after Paramount Pictures sold their theme park division to Cedar Fair. The ride is enclosed entirely indoors. It accelerates from 0-54MPH in about 4 seconds. I remember riding it back when it first opened. It's pretty intense, especially since it's in the dark.
You can see on on-ride POV here (headphone warning): ua-cam.com/video/-dEr5WJd9ZE/v-deo.html Here's a behind the scenes view of it with the lights on: ua-cam.com/video/cMxrZc8JO7A/v-deo.html
"I know what's comii AAHHHHHHH!!" Hahaha! Laurie, it's always a great feeling of accomplishment when you get to see your work still in action after years of service!
Making videos on any subject, broad yet always interesting subject exploring. i am only familiar with LIM coasters from RCT, so this is neat insight into its operation.
I'm really nervous around very big spinning things, there's so much energy in it that it's really hard to understand how angry a large disk is when it spins, to harness the energy in such a new way is so cool
Fatigued metal on cars that see tens of thousands of cycles makes me nervous; they all fail eventually you just gotta hope it’s not when you’re there that day.
@@iJacker I'm sure there's a few redundant fail safe mechanisms, I'm sure there's designed failure points but still, as an ape will a big brain it's scary
im not much into ollercoasters at my age but i do have an appreciation of fine steelwork..Nothing like an amusement park for a display in over engineering is there..Oh i loved your gates too of course..i enjoyed this episode guys, thankyou
Laurie and Anni I think I want more! Love the mechanics of them roller-coasters! Either with a flywheel or with magnetic power I love them both! I'm here for the algorithm! Peace
Any content explaining the mechanics of fairground rides would be excellent, this was extreamly interesting, also why don't you design and build a ride of your own? Not a roller coaster but a thrill ride using everything you know about engineering. That would be a good challenge for you guys. This was a brilliant show 👏
FIN-TASTIC Video!! :) I have watched all of your content for a long time, and it just keeps getting better, more fun, and more educational! Cheers to you from the USA!!
This was a great show. I advise watching on a BIG screen TV/Monitor. The visuals on the ride are outstanding. You might have to build a liner electric motor just to ram into things.🤔🧐🤷♀️
I have never ridden a jet coster but I feel like those things would push my lunch right out of my stomach. The second ride made me wince just from the video.
Rollercoaster enthusiast here. Yeah, I was the guy in the first car, hands ahead of me like the old Superman series, doing a Rebel yell. Now I have to find a way to get to Finland...both of those are on my bucket list.
Oooh. Stuff like that gives me the willies. All that power, all that precision needed, and really- One little flaw, mistake, a sharp grain of sand.... *gulp* Yup. Big phobia. Don't worry. I'm not complaining. I'm commenting. And going over here for a bit. :D
That second ride is the only one I have ever seen where the final acceleration is electric. A serious issue for roller coasters is what happens if there is a power failure during the initial acceleration/ energy input stage. Old style use electrical motors to raise the car against a ratchet, if the power or motor fail the ratchet catches the cars. Once the lift is completed the only force required is gravity, which is damned nearly 100% reliable. Catapult launches were most commonly achieved by raising a weight (against a ratchet), coupling it to the cars and releasing it. Again, gravity isn't going to have a power cut or blow a fuse part way through the launch. Flywheels will never just cut out, so they are a reliable energy source. The significant feature of the linear motor launch is that if the supply or motor fail before a complete launch, the track is designed such that no harm will occur. Ill admit it has been a while since I followed 'coaster design, but this is a huge advance in launch systems.
tons of coasters have only electric launches, they either only have one train like this one where nothing bad happens if power fails or they have brake fins that raise behind the car as it launches to stop the car in the event of power failure or rollback. look up outer limits/ poltergeist/joker's jinx for examples of multitrain pure lim launch coasters from the late 90's this is nothing new.
@@Mister_Brown thanks, I stand corrected. I'll admit my knowledge is purely UK based, there are no LIM launched roller-coasters here. Its probably a local 'elf' n safety thing. Edit add, the online roller-coaster database I just saw states that there are 22 such rides in the world, not all of which are in operation.
You need to come to Santa Claus, Indiana, USA, to Holiday world. They have 3 wooden structure roller coasters and several more modern metal ones. Roller coaster fanatics come from all over the world to ride them. It is not uncommon to see people get off of one of them with wet pants or the park crew having to hose out a car seat or 2. Their new one for this past open season is a water coaster that is also rated as one of the world's top coaster rides. Probably more coasters in one place than any other place. The park opened as Santa Claus Land in the early 1950s. We went there the first year it opened and it was basically kids rides. In fact, when they put in the Water Coaster they removed the last original ride, the Santa Train that was the signature original ride.
Please make some more shows from the park. Maybe a big clear water jug with neutral ball or toy. Put the camera 🎥 aimed at the water jug . The we could get an idea of what our stomach is doing 😀🤷♀️
2nd try. Maybe borrow an aviation display from Garmin. Use a heads up display or superimpose display over the ride. This would give you roll, pitch & yaw along with speed. Maybe add a G force monitor. Also I would like to see the camera mounted at the rear car of the roller coaster about human head high.
You should cover hydraulic launch coasters. The hydraulic launch mechanism is basically the flywheel system on steroids, with the energy for the launch stored as pressure in accumulators, then released into hydraulic motors that turn a winch that pulls the train via a cable. The top three fastest coasters in the world all use this system.
Some roller coasters use a giant moving weight to power the push car via a similar cable system. The one I rode on just did one vertical loop back and fourth, no turns, and it used those loud friction break bars that would 'bang' open and 'bang' closed before breaking each time. The weight was inside one of the towers that held the loop up; the cable system had the cable loop with the push car like in this video; and then another cable system for the tower weight (a huge concrete weight If I remember. That thing worked! The start really had a subtle but super solid punch to it and the force was unrelenting until it let go. That's what I liked about it. That one is gone now :-(
i don't think there are any weight drop launched loops left but there are a few flywheel ones which really have the same experience, if you're in the usa knotts berry farm has one called montezuma's revenge and indiana beach is building an old one they bought next year
This design of launched rollercoaster is actually the oldest one. Anton Schwarzkopf built some of the first launched rollercoasters, his shuttle loop coasters, using this launch system.
40 MJ is also the amount of energy 1 Litre of diesel has. With about 50% efficient engine, that flywheel can store enough as using 2 litres of diesel in a generator. That's the problem with fossil fuels... They're actually great...
But you forget, the energy transfer for diesel would be slower. You would have to burn that liter of gas simultaneously to get the same thrust profile as the flywheel, since flywheels can transfer energy near simultaneously. A gas based engine for this would be arguably less fun to ride. There is more to energy than energy density
The point of the flywheel is it can provide a huge torque in a very short time. The alternative is to use a huge motor (many MW) which would probably blow out the power grid as well as have a huge starting inertia. With the flywheel the electric motor is always spinning and wouldn't need to have a high power rating. Probably a couple of minutes between rides to recharge 4MJ - a 30kW industrial motor would do the job nicely. The linear motor will discharge capacitors (which are charged much slower) to provide pulses into the electromagnets. Let's say the 1MW is distributed over 20 electromagnets that's 50kW peak power per magnet. Each magnet would only need to be switched on for 1ms or so giving a stored energy of 40J per capacitor. Assuming the caps are charged to rectified line voltage (400vdc) the capacitors would only need to be 625 microfarads which is a very reasonable value. Given the coil impedance is likely to be ohms the instantaneous coil current is several hundred amps which is very reasonable for an industrial linear motor. To charge all the capacitors in a couple of seconds would only demand a power supply of a couple of kW and like the industrial motor very easy to run off the power grid

The weight was inside one of the towers that held the loop up; the cable system had the cable loop with the push car like in this video; and then another cable system for the tower weight (a huge concrete weight If I remember. That thing worked! The start really had a subtle but super solid punch to it and the force was unrelenting until it let go. That's what I liked about it. That one is gone now :-(
i don't think there are any weight drop launched loops left but there are a few flywheel ones which really have the same experience, if you're in the usa knotts berry farm has one called montezuma's revenge and indiana beach is building an old one they bought next year

This design of launched rollercoaster is actually the oldest one. Anton Schwarzkopf built some of the first launched rollercoasters, his shuttle loop coasters, using this launch system.
actually the weight drop system predates the flywheel system but schwarzkopf used that too on even earlier launched loops.
Motogee is a Schwarzkopf coaster.
Great video!!! Thanks for the unique view!
So nice to see. The Flywheel seems to be alot of effort compared to pneumatics or hydraulic acceleration. Alot of wear on the clutch and break.
No clutch wear really as it has torque converter to take the big speed difference.
40 MJ is also the amount of energy 1 Litre of diesel has. With about 50% efficient engine, that flywheel can store enough as using 2 litres of diesel in a generator. That's the problem with fossil fuels... They're actually great...
But you forget, the energy transfer for diesel would be slower. You would have to burn that liter of gas simultaneously to get the same thrust profile as the flywheel, since flywheels can transfer energy near simultaneously. A gas based engine for this would be arguably less fun to ride. There is more to energy than energy density
The point of the flywheel is it can provide a huge torque in a very short time. The alternative is to use a huge motor (many MW) which would probably blow out the power grid as well as have a huge starting inertia. With the flywheel the electric motor is always spinning and wouldn't need to have a high power rating. Probably a couple of minutes between rides to recharge 4MJ - a 30kW industrial motor would do the job nicely. The linear motor will discharge capacitors (which are charged much slower) to provide pulses into the electromagnets. Let's say the 1MW is distributed over 20 electromagnets that's 50kW peak power per magnet. Each magnet would only need to be switched on for 1ms or so giving a stored energy of 40J per capacitor. Assuming the caps are charged to rectified line voltage (400vdc) the capacitors would only need to be 625 microfarads which is a very reasonable value. Given the coil impedance is likely to be ohms the instantaneous coil current is several hundred amps which is very reasonable for an industrial linear motor. To charge all the capacitors in a couple of seconds would only demand a power supply of a couple of kW and like the industrial motor very easy to run off the power grid
that whirr of the linear motors...

Your reactions was so funny 😂😂
Ok, if you name one thing Anne is good at it is laughing and yelling. This makes her a pro roller coaster tester.

“That’s something I could build” sounds like a challenge 😁
Fun to see. Thanks.
More of these How Things Work videos please.
You have some fun rides. Have you completed the catio yet?
So, you are telling me we have to visit the amusement park the next time we visit you in Tampere? CHECK!
