It would be cool if you roll out of the station and climb 90degrees and get launched straight up. It would probably take a 50000 hp motor to do it, but i think intamin could design it great enough. the launch cable would have to be on a pulley to be able to go up then back down to the motor room on the ground. it would be awsome launching from 0-130 in less than 3 seconds vertically!

Let them learn how to launch strait first
you need to learn to walk before you can run

VTBC has a launch going up at 90* and its very cool.. But I dont see the need to go 130mph up... Unless your going to have like a 600foot tophat....

yeah i can see them trying to make the 600 ft tophat in the next few years. *rolls eyes* im not kidding. i think they will try. they need to get freaking kingda ka and top thrill dragster to work first.

the G forces would destroy someone.

^Anyone heard of the space shuttle? There is no way a coaster would have more g's than that and The shuttle usually doesn't destroy people...

No, Volcano doesn't have a vertical launch. They're both (almost) level. The second launch is right before it re-enters the mountain, after that huge turnaround.

You all missed some points.

First, the "destroyage" of G-forces totally depend on duration. Simply sit down on a wooden chair and you'll get 10++ Gs in your "bottom spine". No joke!

Second: The minimum required acceleration for gaining speed on any vertical launch is just "anything more than 1.00 G". So by having the "usual" launch forces (and durations) of 1.4 - 1.7G on a vertical launch, there is both way enough speed *and* height gain for quite a large coaster.

Third, since you would go directly upwards, there isn't even demand for high speeds, since the height gained then will provide lots of potential energy itself. No need for a long and forcefull launch even.

My conclusion, this could easily be done, in case some manufacturer actually would want to do it.

What the hell does that mean?

btw, a vertical launch will be awesome!
although i don't hope they're gonna make it a shuttle cuase then it will suck!

It can't be done easily. Before spitting such radical ideas such as to get a Rocket Coaster to launch from a vertical "riders facing the sky" position, you have to understand how the launch mechanism works on this coaster. The train would first have to be locked into its position somehow so that it doesn't roll backwards or (downwards) before the launch. Then the launch itself...you have to have a certain amount of track length for the actual launch and then another stretch of non-launch track to kill the train's speed before it crests the top. So even a 80 mph vertical launch would result in the need of a 400+ foot first hill. In addition, it requires much more power to launch a vehicle vertically than it is to horizontally.

It has lims going up out of the Volcano....

/\ Yeah, but Volcano really doesn't have any correlation between the concept launch we're discussing here...

Volcano is already moving at 70 mph before it even hits that vertical stretch of electromagnetics to get it up and out of the mountain at 155'.

This guy who made this thread is proposing a Rocket Coaster that launches from a standstill vertical "face up" position...

I think its possible but not likely. I'm not sure but I think the set g force would have to be 1 more than the normal flat g-force. I may be wrong but I think the formula is [(sinA)*G]+1. Take that and plug it in for this scenario; 90deg, 1.5g launch. [(sin90)*1.5]+1=2.34g. Thats what the motors would have to be set at. Look at TTD/KK reliability, they're set at 1.5 or around I think, adding 1g to that would make it even MORE unreliable.

Maybe in 2103 it will happen.

[quote=raser]^Anyone heard of the space shuttle? There is no way a coaster would have more g's than that and The shuttle usually doesn't destroy people...[/quote] Actually, coasters have more G's than space shuttles. Space shuttles have only a 3.something G launch, while we have rides like dodonpa reaching 4, so we in fact have made coasters more forceful than shuttles.

/\ Well, it's like this...We have coasters that produce more G-force than the Space Shuttle, but those are only for brief moments (a few seconds at most). The Space Shuttle sustains a 3.0 to 3.5 G-force for MANY MINUTES during take-off. G-forces can be tolerated by the body, but it all depends on how long the body is subjected to the G-force for.

^ Exactly, you can hit 7gs but you can't hold 5 let alone 7.

Look at Red's post. He explains everything perfectly in it.

What everyone needs to realize is that the current hydraulic launches are powerfun enough to do what you are asking, and that they do not need to launch at the same speeds because of the fact that they are going up already. Give me a launch that takes me up at 20-40 MPH up the side of Ka to the crest, and on the way down I'll be going around the same speed, if not faster.

__________________

Volcano's LSM's are level, the first launch segment following the 90 degree turn are all level and so are the second boosters follwoing the 180 degree turn before entering the mountain.

Montu pulls more g's then the space shuttle... Pulling more g's then the space shuttle isn't a very extreme thing to have happen, the duration is shorter though.

That'd make for a pretty dull launch...

__________________

Yeah, both of Volcano's LIMs are definately (almost) level. There are no LIMS while going up. The track twists slightly while going vertical, so there's no way of having lims there with the magnets that are currently on the train.

Why would you want to launch up anyways? You'd have almost no sense of speed or height or even going up. If you've ridden a space shot, you know what I mean.

Because it's different.

Well the people who were talking about the space shuttles i remember hearing that the astronauts experienced 5g+. I think we should wait for intamin to perfect the launches that go at a 5 degree angle(or somthing like that)before they start thinking of launching at 90 degrees.

[quote=redunzelizer] just my 15.696 m/s²[/quote][quote=Cephas]That'd make for a pretty dull launch...[/quote] Ok, so let's see then...

V0 = 0 m/s [I](start speed)[/I]
A = [I]15.7 [/I]m/s² [I](acceleration)[/I]
T = 3.6 s [I](duration of acceleration)[/I]

thus resulting speed: V1 = 56.5 m/s ( ~ 126 mph)

That's (in simplified and averaged calculus) pretty much about what Kingda Ka should deliver (when operating). It says KK will do [I]"0-128mph in under 4 seconds"[/I]. ;)

So Cephas, just in case these [I]15.7 [/I]m/s² make [I]"a pretty dull launch"[/I] for you, we can only assume that no one on this planet will be able to help you anymore...:D :p

P.S. And don't even try to use such high numbers on any vertical launch, as in current discussion. You would have go upwards *another* few hundred feet to master any top hat then...:eek:

I get a concept for the ride, theme it towards space, have the train look like a shuttle and have it roll into a verticle section of track. Next the track moves with the train on it towards the launch tower while the riders are on it. Once at the tower the track locks in place and the countdown starts, once the countdown gets to zero you hear liftoff and away you go...

sin90º is 1, so it would be 2.5g's.

But anyway, there is no way it would go 130 mph vertically, that sounds like something a six year old would say.

What about using a weight launch with a bunch of pulleys?
