X-Car Posted July 9, 2010 Posted July 9, 2010 I'm working on this Bugatti Veyron coaster. It goes 253 mph, soon to be 270mph, because Bugatti just recently released the Sport Veyron which goes even faster. I plan on theming the hell out of this ride and adding stands along the mid course straight. This is just a video of the progress that I'm making on the ride.
davisal771 Posted July 10, 2010 Posted July 10, 2010 While this looks AWESOME... I'm confused on a few things. 1. How are you getting the train to go 250 MPH? I thought the simulator capped LIM speeds at 126 MPH. 2. How is this going to be survivable? This could be fairly dangerous in those turns. You can't put more 5gs on a rider. Those turns are looking like 8+. I'm anxious to follow this, and see where it goes
X-Car Posted July 10, 2010 Author Posted July 10, 2010 ^ 1. The unregistered version of the construction kit has a tool (The Power Tweaker) that allows you to put in speeds as high as you want...as well as forces as high as you want. 2. The G's never go above 5.9. If you watch in 1080p, you can see the force values pretty clearly.
Sasquatch Posted July 10, 2010 Posted July 10, 2010 5.9Gs would be fine for an instant... but 20 seconds or so?? What's with the huge helix??
X-Car Posted July 10, 2010 Author Posted July 10, 2010 The track barely fits on the map. I have to have the helix... I trimmed it down half way through so I could have a twister layout towards the end of the ride. Just look at the comments for the video on youtube; I've explained it a few times already.
Pingu1651 Posted July 10, 2010 Posted July 10, 2010 And now presenting, the world's biggest helix! No, I'm just joking. If I may make a recommendation though, DON'T bank the turn exactly 90 degrees. Make it a little less so you can take some of the vertical G's away and add some laterals. You can probably safely hit 3.5 vert and 1.1 lat. I don't really know though.
davisal771 Posted July 10, 2010 Posted July 10, 2010 I should get the construction kit. I didn't even notice the force values. I should have paid attention to those. This could be a really intense, crazy coaster.
X-Car Posted July 10, 2010 Author Posted July 10, 2010 ^^ It actually doesn't hit 90 degrees during the turn. I think the highest it ever gets is 75 or 80. The thing about G's... Vertical is only measured vertically relative to the train....(obviously)...and lateral is measured horizontally... So, if you change the track from 5.9 vertical G's to 3.5 vertical and 1.1 lateral, you still put the rider under 5.9 G's, it's just divided between two accelerometers. If there was a third G-force measure in the direction of the net G-force, it would still read 5.9. Although, if I did that, people who only look at the color of the numbers would not be commenting on it any more. It's not really meant to be real and I can't really change it now, so I won't. Another reason why this ride isn't realistic.... Each wheel of a car full of people who weight 150 pounds would be under roughly 3835 pounds of force during the 5.9 G turn. This combined with 253 mph = destroyed wheel barrings.
mightbeawannabe Posted July 10, 2010 Posted July 10, 2010 ^ But remember, NL doesn't show rotational Gs but combines them with the lateral so there are really four different types of Gs put on a rider. Rotational, Lateral, Vertical and Acceleration. Also, 150 lbs. a person for one load bearing wheel with four seats per car is a little unrealistic. There are ginormous people called ACERs and the love to try to fit in those seats so the weight per seat is nearly 300ish lbs. maximum. But you also need to factor in approximately 1/4 of each carriage's weight (frame, wheels, harnesses, seat, hydraulics, etc.) for each seat of the train (plus an extra 1/6 for the leading car) and then you have the minimum amount of weight/force that will be required for track and support integrity. But, there are more things to calculate. The duration of the amount of force, momentum, kinetic energy of the train.....By all means, have fun with it! But I am certainly no expert.
jarmor Posted July 10, 2010 Posted July 10, 2010 I would have thought a 253+ coaster would be more than one stretched out helix. I understand the thrill and excitement of going that fast but if you dont have the space to make the layout able to take advantage of the speed it leave a ride like this...
andyuk200523 Posted July 10, 2010 Posted July 10, 2010 Interesting layout - however.....5g Launch!?!?!?! How many necks do you wanna snap with that? Also the hydraulics required for that speed in that short period of time would never work if Intamin made them
