New inversion?

Wednesday, June 6, 2001 7:50 PM
Hey i was wondering if you could make up a new inversion, what would it be like? I always have wanted to see a loop do the opposite of going down instead of up into a loop. Like an upside-down loop. I have also wanted to see a new inversion on an SLC or flying, I started making it on Solid Works. It starts out coming out of the station into a small helix with an inversion in it. Kinda complecated but if you could see it, you would understand.

I'd like to see a tophat inversion with an inline twist in the middle of it.


On a suspended coaster with a vertical drop, 1/2 of an inline twist just before it, so that the car is on the opposite side of how you approach the drop. This could work on a sit down too, like the old Z-Force (is it Flashback @ SFoG now ?), except that instead of leveling out right away, it would keep dropping like Oblivion (kinda like a airplane stalling)!


Imagine the spiral side of V2, except that the track continues, arching over the top and back down a 2nd spiraling track !

I could spend hours and hours thinking about this. I suspect this is gonna be a long thread.

sfmm, a loop going like that would pull WAY too many G's. Think about it, you would be forced out of your seat against the shoulder harnesses...OUCH

Sfmmlord, I have had similar ideas, but have only tried them in RCT!!! And yes the G's can be high! I wondered why X Flight doesn't incorporate sending riders around the outside of the loop. But after riding it, I am glad they didn't!! Just rolling over was hard on the legs where they rest on the restraint. I think with different vehicles it would be possible. B&M inverts go on the outside and don't hurt because your G's pull on your butt!
Scale model coasters and rides.....

Nope, Flashback is SFMM.

Why can that never happen?

I got one. I call it the Knot. For a brief demonstration (heres how it goes):
1/2 barrel roll
1/2 corkscrew into
half loop and a
barrel roll
I thought of this playing with a bendy ruler one day in math. I can recreate a lot of inversions just by showing you that.

I want to see more loops like the one on Mahatten express in Las Vegas. It's similar to a dive loop, only before you go down the loop, you travel upside down on a straight-away for awhile before going down.

My idea is to have two full loops side-by-side, (not one in front of the other), but as you come out of one, the track twists a little to take you into a parallel one.

Yeah, you're was at SFoG before that. I forgot they moved it again.

Aren't B&M coming up with a new inversion for AIR?, I remeber reading something like that.

I heard that AIR will have just the one, world-frist inversion - I hope its not true - but look at the short length of track, it has less than 6 turns in it and its compact. Still cant wait though.

Martling, the side-by-side loop thing that you're talking about has been done on Texas Tornado at AstroWorld, and it is GREAT, especially with the 80 degree twisting spiral drop that precedes it! But my idea which has yet to be done is an element that I call the "twisted S curve". It looks like a normal S curve, until you examine it more closely, and then you realize that it has an inversion in it. You begin with a 180 degree turn that's banked at 90 degrees in the center, but on the exit path it keeps banking over to turn you upside down, instead of returning you to an upright position. Then you enter another 180 degree turn in the opposite direction, which is a mirror twin of the first 180 degree turn, so by the time you exit the element you're right side up again, and you've been turned upside down in the middle of the S curve. I don't know if it could actually be done, due to the strong lateral G's that it would produce, but what a ride it would be! I hope a new coaster gets one soon!

I've thought about the upside-down loop thing too, but that would pull more G's and hurt even more than SFGAm's Shockwave! (I'm not a big Shockwave fan.) In fact, it would probably kill lots of people. I'd like to see any inversion on a would rock with the swaying cars and all.
