Over the past few years launch coasters have been popping up everywhere. Rides like VelociCoaster, Hagrid's Magical Creature Motorbike Adventure, Guardians of the Galaxy: Cosmic Rewind, and Tron, are all magnetic launch coasters - as are many other rides around the world. But, how do they work, and why are they so popular, and will we see more in the future?

As time goes on, I think LSM can advance up to the level of forcefulness of a hydraulic launch.

@BlueZirnitra Жыл бұрын

@@ICU306 I don't think that's the case. It may come close, but generally complex electrical systems like this require orders of magnitude more power (to the point of impracticality) when you try to scale them up beyond a certain point. Hydraulic launches were always fast, all you need is a bigger accumulator, bigger pistons and more fluid. Different mechanical solutions to generate power always differ in what they are best at, and I believe LSM's strong point is efficiency and flexibility when when you're not trying to break acceleration records. There never has been a replacement in industry for the inherent power of hydraulic pressure. Heavy machinery, industrial robots etc, use them almost exclusively for a reason. A magnetic launch is unlikely to ever achieve the same *force* as a direct mechanical connection to a massive ram. Top speed over a distance though, sure, because you can just add more motors after the hydraulic would run out of steam.

Parks also like how they usually have a smaller footprint since you don’t have to have a massive lift hill to get to quite a high speed, the lack of a lift hill being particularly attractive to parks like Phantasialand who have issues with height restrictions. Great video!

LIMs could be making a comeback (though only on smaller roller coasters). Vekoma used LIMs on two of their 2023 family roller coasters: Big Bear Mountain and Lightning. Since permanent magnets (for LSMs) are heavier than aluminum fins (LIMs), I'd be curious to know how light a train (not including the fin/magnet) has to be for LIMs to use less electricity than LSMs.

How do you explain the catch cars on the Vekoma LSM Launch Coasters: Rock N' Rollercoaster (and Xpress: Platform 13, which is the same ride, but outdoors with a few less blockbrakes). ? Since now it seems like the Catch Car is not needed with LSM technique?

@coasterbot Жыл бұрын

Great question! I'm honestly not too sure. I imagine they benefit from removing the permanent magnets from the train and placing them somewhere else. This could mean more powerful magnets on the catch-car, and a reduced train weight (which I imagine would already be heavy due to the sound systems).

Sounds good but, there's something special about the ANTICIPATION of the climb UP the hill before the drop. Launch coasters are hella' fun, but it feels more like a quickie than a long, intense sex session, if you konw what I mean. That feeling in my stomach as I hang in the balance as the coaster slowly begins to drop over, or the beautiful view on the way up, that feeling that you can touch the sky and overlook the scenery. The calm before the storm, than BOOM! There's a place for launch coasters, no doubt. BUT BUT BUT! Theme parks mustn't be so tempted to make EVERY coaster a launch coaster. It's the same reason wooden coasters have a special place in my heart next to steel coasters. That "rikety rikety" feeling is unmatched. Fun is fun, and the "build up" coasters as well as the "fast paced caosters" are both neccessary additions. Some parks realize that variety is best, not a one-size-fits all kind of coaster, such as Cedar Point. They just "get it".
