Manipulating Launches

LIM's and LSM's can be changed so that the speed and the intensity of the launch are different. They can range from launches like Flight of Fear or Wicked Twister, to being used as a chain lift on California Screamin'. Can the air and hyrdrolic launches do the same?

I am sure that they can change the speed on a launch, because if you noticed Wicked Twister did not go as high on the spikes as when it first opened, I think they lowered the speed to reduce damage to the bad welding jobs. Or something like that.

It does now.

Alf, read the post again please. :)

Yes they can change the speed on air and hydraulic launches too as they have booth been testing at much higher speeds.

Oh, gotcha, I think I misread it. I thought he was asking if they can change the speeds of LIM launches. Thanks olov.

Didn't they test like Hypersonic: XLC at like 100 MPH? Or am I wrong again?

In one of the recent threads I did some really bad math and calculated that the Thrust Air coasters in testing exceeded something like 15% of their normal operating speed. Xcellerator exceeded it's speed by 30 some percent.

Of course, on the thrust airs (I'm not certain about the rockets) every launch is manipulated by weighing the train, and then using the appropriate speed to launch every train, regardless of load, to the operating speed (to make the big hill).

remember, xcelerator was reported to be able to test at up to 117mph!

Wouldn't the speed of a launch on a hydraulic or pneumatic launch be changed by the amount of stored pressure? You'd be able to change the speed of the entire launch, but not during the launch (as if you'd want to do that). LIMs and LSMs can change speed by changing frequency at any time.

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

While the speed can be adusted on all launched coasters, (actually I don't know about the old flywheels) the speed at the end of launch is pretty critical on any launched coaster except an impulse. Too little speed and you don't get over the hill. Too much speed and the G forces get out of hand.

LIMs can be designed to work a different speeds depending on what you want to do. You can make them behave like a rail gun with many G acceleration, or they are often used for people movers that only go a few miles per hour. Some :LIMs are even used in steel mills to pull metal through extruding dies when it is hardly moving at all. It's are good way to pull a chunk of red hot metal and hold a nice even tension.

No, you are probably thinking of Xcelerator, which was clocked up to 117 miles-per-hour on a test run.

dang, I was wrong again. Oh well, what else is new?

They did test the Japanese Sister ride above speed though. Yeah, Xcelerator tested at 117 mph, theres a video of it testing that fast somewhere on the internet (try asking on ACN), and it does fly over the tophat.

Thrust air coasters have been tested up to 120 mph. Here is link validating my speed

I'm not good with the "technical" terms here, so let me just get this straight here, and please correct me if I'm wrong, or tell me if I'm right:

One type of launch is LIM

Another is LSM (can somebody say what that stands for?)
Another launch is Hydrolic

And another one is compressed air

I'm not quite sure what LSM is (as I stated above) so I'm not sure if it's a type of launch or not. For all I know I could be completely wrong (help me please!:))

Yep. That's about right.

LSM stands for Linear Synchronous Motors. It is the type of lanuch the Superman: The Escape at Six Flags Magic Mountain uses. I think that there are a few Vekoma coasters that use LSM's, but I'm not sure. LSM's are similar to LIM's but there are a few differences. I don't know what they are, however.

I wouldn't see why they couldn't manipulate launch intensity/speeds. In the case of hydraulic launches and air launches, all they would have to do is increase a pressure threshold...but then again, I'm not a mechanic or engineer. :)

Does anyone know the difference between LIM and LSM?

LSM's shriek louder. :)

LIM's are coils of wires that produce waves to move the train.

LSM's use alternating magnetic fields and require a push for the coaster to go.

This is off memory, it may be slightly diferent. Correct me if I'm wrong.
