If you all have any questions pertaining to anything that you see in the updates, please let us know and I'm sure somebody can give you a thorough answer...

I forgot to add these...

Sally Corp had a demonstartion of the new shooting ride coming to Legoland California. It was your pretty typical Sally shooting ride, but this time it shot water back at you!

Sorry about the blurry photos, the lighting wasn't that great inside the expo.

Do you care to extend on what Sandor Karnacs said about Maverick's heartline roll?

[Michael]

I enjoyed the update, however I was disapointed that Intamin AG had nothing about Farenheit :(

[Mike T]

In regards to Maverick:

Sandor had the opportunity to ride Maverick 8 times with the heart-line roll, and it was from the tests that were the decision maker on Maverick’s delayed opening. On paper and in computer design programs, the roll functioned to Intamin specifications:

That is: that a ride’s force has a margin of error in a 20 millisecond time window. This means that no matter how high the force (generally not too extreme, but you get the point) the rider will not feel its presence if it is under that 20 millisecond time frame.

Maverick was designed with moderate forces in mind, nothing too extreme; and that goes with saying about the heart-line roll too. When the ride was being tested back in the last week of April of 2007, an accelerometer was attached to a train to determine force values that could be matched up with the initial design in the computer program. It was determined by the accelerometer that the heart-line roll was pulling a centrifugal force that was drastically higher than what was expected from it. The roll also sustained that force for 40 – 60 milliseconds, meaning that riders would be able to feel the roll’s uncomfortable forces.

Now before we jump to conclusions, it must be added that the roll could be ridden by a human, but for the nature of the attraction that Cedar Point was dealing with, it was not necessary. Sandor laughed when asked about the heart-line roll, giving the impression that it was extremely intense.

It was his decision to remove the roll, not as a safety precaution, but more so as a cost saver to Cedar Point. Because of the roll’s intense forces, the trains would have taken a drastic beating, and over time they would need to be replaced. Sandor said that had the roll stayed, Cedar Point would have to replace 6 trains every 5 years (keeping in mind that these trains have to react to an electro magnetic field, making their costs high as well). According to the post calculations, the trains would have been brutalized by the roll, and that was the reason for the amendment in design.


As for Fahrenheit:

A unique feature about the attraction is that due to its vertical lift feature, the ride will not include anti-rollback devices. As compensation, the ride will be driven by a double lift chain, and in the instance that one fails, the other will casually bring the train to the top. Although this sounds a bit risky, the design standard is completely safe, because the trains being carried up the lift are not only smaller and lighter, but are being carried by an overly compensated driver that is meant to carry loads that are many times the size and weight of a single Fahrenheit car.
