Speed-WOW

I'm not sure why anyone is assuming this ride will not have a constant acceleration... if in fact it does, then the speed will be 30mph after 1 second, 60 mph after 2 seconds, 90 mph after 3 seconds and 120 mph after 4 seconds.

Here's a little chart that might help(speeds will be in feet/sec and distances in feet)

time / top speed / avg. speed / distance / total distance

0-1 / 44 / 22 / 22 / 22

1-2 / 88 / 66 / 66 / 88

2-3 / 132 / 110 / 110 / 198

3-4 / 176 / 154 / 154 / 352

Something that you guys keep assuming is the 4 seconds figure. They say that it launches to 120 in less than 4 seconds. If you go to the promo video, the very last pov has a timer at the top of the screen. The train is already in the pull out at 3.3 seconds. The time it takes to get to 120 will be considerably less than 4 seconds.

I think we should leave the physics to Intamin, we should just enjoy the ride. Afer all, acceleration is just a = DV/Dt = (V2 - V1) / (t2 - t1). Yay polymer engineering classes!!

Using that Forumula, one can figure out that Dragster's launch has twice the punch to it than Superman the escapes stats (the original ones.....no way in hell that ride is normally 100MPH these days, its like 0-80 in 8 seconds...at the lower speeds it takes more time to get off the launch). The bad thing is though, Xcelerator has 20% more punch to it (also note the extremely short launch track-you can walk along it while holding your breath-its a lot shorter than Dragsters). Really disappointing that Cedar Fair would tone down the launch........The one S&S launched onein Japan (Dadopa or something similar) is still a more insane launch than any other, by far! I'm really intrested in under 4 seconds really means. Will it be 3.6 seconds or 3.95 seconds. It makes a big difference in ride experience, I'll tell you that much.

About the Hydraulic Lauch- The acceleration/G forces are pretty sustained throughout the launch, unlike the LIMS/Flywheel Launch/Air Launch. Its a good advantage. Probie, be sure to note that. Thats one of the reasons the launch system was invented.

There are so many things wrong with that animation I wouldn't know where to begin. The lines of the track aren't even straight. Watch in the reverse-POV how the train shifts around in the pull-out. It's no Keith McVeen animation, that's for sure.

I'm sorry, but that's simply not how acceleration works. RollerCoast2319 has the right idea.

We don't know anything about this ride's launch system, this could therefore never be settled, it's all opinon. I'm sure it will creep forward a bit to lessen the intial movement forward, power tower does that, but once again, it comes down to the fine details of the hydraulic system, which only Intamin knows about. I'm not saying shutup about it, just that like any great physics equasion, if there are too many unknowns, it's not possible to figure it out. Plus the acceleration is going to vary too much in it's different stages.

No, it actually rolls back a few inches (although the video does say it can roll foward), it stops for the 3 last orange lights, and then the ride launches. At least on Xcelerator it dows.

It's amazing how building a launched coaster makes everyone a physics professor. If you don't really know what you're talking about, don't say anything at all. That's the Silver Rule, it's not quite as imortant as the Golden Rule, but it's close.

What do you mean? This is the exact same system that Xcelerator uses to launch it's trains.

On one end of a closed chamber, there is a cesspool of hydraulic fluid, while on the other end, there is tank with liquid nitrogen. In the middle of these two substances is a piston. During the launch sequence, hydraulic fluid is flooded into the piston chamber, then the liquid nitrogen is flash-boiled, creating a massive amount of heat and pressure. The nitrogen gas forces the piston forward and sends the hydraulic fluid through a turbine. The turbine connected to a cable that is hooked below the train spins very fast and causes the train to accelerate to its maximum speed.

What is it that we don't know about the launch system?

You are correct. Some people here have no clue what they're talking about. First off it was the backwards launch, now this. Use common sense.

On the promo video it said it was a catapult launching system.I was wondering is this the same system as the hydraulic?

No.. in fact, they decided against the hydraulics and replaced it with a giant rubberband stretched between two posts.

Go watch the promo it says it has a catapult launching system not hydraulic.

Go grab a dictionary and look up the word sarcasm.

I'm pretty sure they're using 'catapult launching system' as a term for the general public. It's the same thing.

I was actually thinking about if a coaster could just use a giant rubber band to shoot a train.

Easing the G-force a little if only for a split second seems like it might help prevent injury. Also at the end of the launch if it goes from 2 G's to 0 G's you would get the same snap affect but in the opposite direction it seems.

Doesn't work. I made a modelf of Wicked Twister and tried that and it didn't work.

Acceleration doesn't have to increase in order for the speed to increase. Actually, you guys should learn a bit about vectors, lol. Maybe then you'll understand quite a bit more about this ;)
