TTD Question

I was wondering if anyone know the circumfrine of the hydraulic drum for TTD. I'v been looking around for it but it seems that they like to keep info like that confidential. Thanks

Why, building one yourself?

What I was doing is designing a "fantasy" rocket coaster on autocad and was interested to find out how many time the drum would have to turn in order to reel in the amount of cable as fast as it does. If i can find out what the radius or the circumfrince is i can figure it out with a little mathematics. I was just curious, couldn't find it anywhere on the net with searchs and figured maybe someone here would know. If you want to close this thread thats fine i understand its not really that important, but at the same time it would be information that i would like to obtain.

Thanks

In some news report back in 2003, Monty Jasper was quoted as saying that the drum spins up to 500rpm. Equating 500rpm and 120mph gives:

d=(120*5280)/(500*pi*60)=6.723ft or 6' 8.672"

I personally am 6'2", and having stood next to the drum in the hydraulic room, I can attest to the fact that it is a little bit taller than me.

While that probably isn't the precise dimension, it should be enough for you to create a reasonable autocad model.

wow. math can be cool. too bad I don't understand what u did :)

Purdue University Engineer..

remember that TTD's actual launch speed is variable. Most times I was there I saw between 122-124. I think I saw 121 twice. IIRC, it rolled back both times, too.. hmmm...

It's also made it over at 119 before ;) Wind can be a b***h. But there are definitely days that it averages 122 or higher.

The geekiness (is that a word?) never ceases to amaze me.

I'd think that the number provided should be a good estimate to make a "fantasy" coaster... and gee if it don't work spin the drum a little faster... or bang on it all day?

Well thanks alot guys, i reason that i asked this was becasue the drum that i had designed had a 31' diameter, witch gives it a 92' circumfrence ( spelling) with all of the mathematics done to it equals about 500mph, for 4 seconds witch is rediculis (spelling). So i figured i would ask the pros. thanks alot guys i can refigure everything to be more realistic.

Yea, lets not get too picky because he did say "While that probably isn't the precise dimension, it should be enough for you to create a reasonable autocad model."

What is the formula for the circumfrince of a circle? Or the circumfrence, for that matter? "Witch" may be something like the circumference? Sorry, MForce, just having some "ridiculous" fun with you. Couldn't resist.

And one thing I want to see on this site is mooooooooooooore--- decimal places. A mere three will never do. Pshaw!
