Simple Question

[hyyyper]

Simple Question: KingdaKa has a hydraulic lauch, right?
now it comes, isn't hydraulics all about water, does this mean KingdaKa will be launch with waterpower? I thought it was lauch with compressed air?

No hydralics means oil our a type of fluid. [dorkhat]

[hyyyper]

wich fluid does kk use?

hydraulic Fluid

which is like oil [oilwar]

[hyyyper]

but how does it work, is oil pumped into something that rotates and pulls the chain with a hell of a speed towards the tower?

basicly but it actually pushes a cart thing down the track

[hyyyper]

wich connects the chain to the train, right?

no there is no chain the cart thing basicly is the chain

[gouldy]

I though that there was an engine at the end of the launch in a building under the end of the launch and when launching, "something" was pushed through a pipe by the hydraulic fluid, and attached to that "something" is a cable, which is then attached to the cart thing that you speak of, which is attached to the bottom of the train until the end of the launch, at least thats my, probably wrong, understanding

Basic hydrualics which in turn spin a fly wheel

Hydraulic systems operate on a simple principle: Liquids cannot be compressed. This means that if you fill a tube with liquid and put a plug in each end, pushing on one plug will cause the plug at the other end to move an equal distance. So hydraulic fluid, usually some kind of oil (automotive transmission fluid is frequently used in amusement rides) can be used to move force from one place to another. Most often, the fluid is used to move cylinders around, to initiate linear motion, but it can also be used to spin a rotary motor. In any hydraulic system you need a supply of fluid, a supply of fluid pressure, and work to be done. To do this requires pumps, reservoirs, cylinders, motors, valves, and an assortment of other special parts

ok, thanx u guys

no prob

it is kinda hard to follow. I was watching a TTD video and a guy explained how the hydrulics. He said the pump oil up against nitrogen or something and creates like 250Bar.

[hyyyper]

see it like this, take a plastic pipe of .5 to 1 meter, (around 3 feet), put a fitting bolt on the end, fill it with fluid and push another fitting bolt on the beginning, than push the bolt into the pipe and the other one will shoot out the other side, if you attach the shooting bolt to a coaster train, it'll reach very high speeds.
if i said something wrong, correct me

No

To prepare the system for launch, the valve (41) is set into the closed position as shown. The fluid pump (39) pumps hydraulic oil (red) from the reservoir (38) into the cylinder (32). The cylinder (32) is a large hydraulic accumulator similar to the ones used on the lap bars. Except that while the lap bars are equipped with bladder accumulators containing essentially a Nitrogen filled balloon, this cylinder contains a piston (36). The chamber (34) at the bottom of the cylinder is filled with Nitrogen, but notice that in this case it is connected to a group of gas-filled bottles (35). As the cylinder (32) fills with oil, the piston (36) is forced back in the cylinder (32), compressing the Nitrogen gas (green) out of the chamber (34) and into the bottles (35).

Once the cylinder (32) is filled and the train (2) is in position, the system is ready to launch. This is accomplished by opening the valve (41) which allows the oil (red) to flow rapidly through the lines to a reversible hydraulic motor (22). The fluid flows rapidly because it is under pressure supplied by the gas charge (34) in the accumulator. The accumulator can release all the energy stored in it by the electric pump (39) very quickly, operating at a much higher volume than the electric pump (39) can produce. As the hydraulic motor (22) turns, the fluid is returned through the check-valve (37) to the reservoir (38). The hydraulic motor (22) is mounted coaxially with and attached to a cable winding drum (24). The launch cables (28, 29) pull the launch pusher (14) which shoves the train (2) down the launch track. Once the launch is completed, the valve (41) is closed to allow the accumulator (32) to recharge. Valve (40) is shifted to its schematically right-hand position to allow fluid (red) to flow as shown by the arrows, supplied by the pump (40a) or other means (pump (39) could be used as well). Notice that this reverses the fluid flow through the motor (22). This reverses the direction of the motor (22) to reset the launch carrier. The exact operation of the motor (22) is not clear at the moment; it is not specified in the patent, and neither Cedar Point nor Intamin has so far been forthcoming with details.

yeah, that basically what he said! I think!

Thats quite interesting, and i learnt alot from that. [:D]
