Airtime

Why is it still so hard for people to grasp that hydrolic launched coasters are completely different from the LIMs on WT? When it comes to hydrolics, its a one time deal.

Enjoy your ride on the Big Bad Bug

If there was a new way...I'd be the first in line.

Yeah, please double check my lapbar before giving the thumbs up!!!

This ride will have great "ejector" air. It wont last a super long time but it will be intense! That is why Knott's has their "staple" rule. They push down pretty damn hard on the lapbars on Xcel and I'm sure they will do the same here. And they also will not lauch the ride until everyones head is against the headrest and all hands are on the grab bars infront of the riders.

Why is it that people still can't spell the freakin' word "hydraulic?"

Spell it with me, kids...

No Spot, there will not be any air time "separated by negative Gs".Rest assured Intamin will give us zero G thoughout that downward curve. And also Majin Heero, STE's airtime IS because the train is going straight up and then straight down not necessarily because it is stalling. Scince the train on vertical track is slowing or falling due to gravity at the same rate as its riders, they feel airtime. So anything moving along a vertical peice of track regardless of up or down will experience airtime provided that there is no mechanical accel. or deccel. devices. Zero g going up, zero g going over, and zero g going down from pull-up to pull-out, AIR TIME...For those with question whether the twist coming down will have any hindering effect on the airtime felt on this ride, the answer is no, not enough to be noticed. WT sure doesn't have that problem.

Ok these numbers arent exact but they are close enough to be somewhere in the vicenity of half a second. I am confident that airtime will be experienced from pull-up to pull-out. The track goes vertical around 150 feet / 45.7 meters, velocity at this point and at that height on the other side of the track should share the same velocity roughly at 40.4 meters/second (mph isnt relevant lol). Distance from this point to the top of the hat is 81.3 meters vertically. Bare in mind im only figuring this through the Y vector (Vertical Motion) assuming that the curve at the top is zero g and most likely is. Scince the vertical velocity deccelerates to 0 from 40.4 Meters/Second, you can only figure it out if you get the average velocity (40.4 + 0 / 2) which comes to 20.2 m/s. (v=d/t) multiply "t", (vt=d) divide "v", (t=d/v) and plug in. 83.1 / 20.2 = 4.1 Seconds on the way up. it looks they will be roughly the same on both sides so multiply that by 2 and you get 8.2 seconds of airtime. Shattering yet another world record.

I thought that one boast of S:TE when it opened was 10 seconds of airtime...

Also, I would think that MF might have over 8 seconds of airtime.

Launch: Tophat: Twistage: Brakes...

...Denial is an ugly thing.

Fluid Coasters - It's very early in the morning as I am reading your posts but I am pretty sure that your logic is quite flawed.

I believe that "airtime" as defined by coaster enthusiasts relates to the floating feeling that you get when a coaster reaches the crest of a hill and it changes direction (from up to down) and your body wants to still keep moving up. The change in vertical velocity (i.e. the vertical acceleration) that the train is experiencing has to be greater than 1G (9.8m/sec/sec or 32.2 ft/sec/sec) in order for "airtime" to be experienced. The vertical acceleration is determined by a combination of the "forward" velocity of the train and the radius of the tophat.

The pull up and pull out radii will NOT produce "airtime". Also, if the velocity of the train is too slow at the crest of the tophat, there will be no airtime experienced there either (Do you experience "airtime" at the crest of the lift hill on MF or MAGNUM when you are in the front of the train? - NO!!).

I'm pretty sure that this is correct.

CoasterBob....wrong!

Have you ridden Xcelerator? The front seat gets a great pop of air entering the crest of the tophat and continues with a mild floating sensation down the other side. The back seat gets crazy air right about when the seat passes over the apex. The airtime coupled with the lateral in the twist was just awesome in the back. I rode in every seat multiple times as it was a walk-on back in October. Back seat all the way.....

And it looks like the CP version may have a slightly tighter apex....maybe to increase the airtime for everyone?!?

Coaster joe - Thanks for the comments relating to your real world experience on Xcelerator. My head is much clearer now (I never should have made that previous post @ 2:30 AM).

Of course it makes sense that there would be airtime potential on the way down. It even makes sense that there will be airtime in the vertical portion of the pull up. That's what gives S:TE its very long airtime!

FluidCoasters - Apologies to you. I don't know if all of your math is correct but your premise is sound (at least I think so now).

------------------

No, I think there are still some flaws in Fluidcoasters' logic. The airtime won't start right when the track goes vertical - rather it would start when the track begins to curve in towards the top with a radius, which doesn't happen until after the twists are completed. Another thing you have to consider is that the train won't have zero velocity at the top - it has to make it over. This would decrease your calculation for time.

CoasterBob, in this case, if the radius of the tophat was the same throughout, you would actually experience more airtime before you reach the crest because you would have a greater velocity. However, it looks to me like the radius changes to coincidide with the velocity changing and produce roughly the same amount of centripetal force/acceleration throughout.

It depends what you mean by airtime. When the track is vertical, riders will experience zero Gs, just like on Wicked Twister.

It's great to live in Ohio!

Yeah that's true, but really you don't feel the zero Gs on WT until right near the top, when you are almost stalled. Anyone who's been on Xcelerator: do you get the zero G feeling when you're going straight up, before the curve to the tophat begins? It would seem to me like you are still going fast enough to not feel it... but I haven't experienced it.

------------------
L-TH-TW-B... "Meh"

The only way to get exacly 0 G's at the tophat is to go an exact MPH to pull just enough up on you to feel like you are weightless. Some people think airtime is being pulled out of your seat for that you need more MPH making the crest a sort of launch out your seat area. In my opinion being completely weightless at the top would feel much better but is very hard to produce consistanly. But hydolics may be very consistant. I rode Xcelerator over 20 times and it has pretty good floaty feeling but it could be better. By the way guys the up and down and crest airtime are going to be NOTHING compared to the launch. You have no idea untill you have been hydrolicly launched. Really, it is one of the best feelings ever. I KNOW I CANT SPELL, LEAVE IT ALONE.

It's really not that hard to learn how to spell "hydraulics" or "hydraulically". It's just ignorant to continue spelling it the way you do after you are corrected countless times.

It'll be just like Xcelerator... you'll be stapled into your seat, you'll launch up the tower, and get airtime without the "air". Your ass will be in your seat, but your upper body is getting airtime, if you know what I mean. On Xcelerator, you get airtime down the tophat. So, I bet on Dragster, you'll get a very nice airtime sensation while twisting 270 degrees.

Got One?? said:

yeah it would increase the ride time. and also the wait. think about it... if it launches twice, you can only have one train. sure...no problem with that.

There are the three transfer tracks out there... Not only could it hold multiple trains, but I bet they could be used to shuffle trains around for a multiple launch setup.

sure it could hold multiple trains, BUT ONLY ONE WOULD BE ABLE TO BE LAUNCHED.

Once again Wicked Twister and #16 are completely different rides and yes this ride will have airtime how much is not certain to me at this point. My guess is about 3 seconds but it all depends on the speed of the train going over the top hat. and i'm not sure about when your going down the drop but going up i don't expect any negitive g's at all because of the simple fact that your gonna be so pressed up against the back of your seat from the 110 mile per hour launch that you won't be able to get any till you start to slow down. Please don't hold me to any of this it is my opion alone and i'm not a big physics person so these are only guesses.

Blue train always wins. . . . .Unless the red train cheats!

Airtime is anything that is considered negative g's, no matter if you feel like your floating in space or if you feel like your going be thrown into space, and to get perfect air time (accord to discovery channel and NASA) you need to go up a 45 degree slope and then crest over and back down to another 45 degree slope which is what they do in the planes for training and what they did for Apollo 13's shots is space to make them look like the actors where really floating in space. Sorry to get off subject but I was just trying to prove a point.

Actually I was kinda hoping for negative G's at the top. Having the ride trying to throw you out of your seat when your over 400 feet up in the air would be one heeluva scary experience. But, They probably won't want to do that for safety reasons. The train will begin its vertical stall imediately after pull-up. Zero G's all the way up through the top hat because the speed will be set so that Zero G's are experienced at the top hat. On the way down it's a free fall. Zero G's. It doesn't look like it's going exactly straight up untill it reaches 200 feet to me. I'd say from 150 feet to 200 feet there would be just a little gravity easing off to zero gravity.
