from 0 to 112 mph (180 km/h) in 1.56 seconds. S&S has brought back pneumatic launches in China with OCT Thrust SSC1000 and Bullet Coaster at Happy Valley Wuhan and Happy Valley Shenzhen respectively. Maxx Force at Six Flags Great America marked the return of pneumatic launches in the United States. Other styles Eddy current launcher (LEM) Magnets are placed under the cars and a series of flywheels coupled to aluminum discs is in the launch zone: there is no contact between the two. The system can be used also for speed up intermediate launchers, and for braking, with static aluminum blades, at the end of the ride. Thanks to the energy stored in the flywheels, the power demand for launching is flat. Two operating examples of this technique are the Drifter at Sochi Park in the Sochi Olimpic Park and at FunWorks, Abu Dhabi (manufacturer I.E.Park) Catapult In the catapult launch, a dropped weight winds a cable to pull the train until it accelerates to its full speed. Dropped weights were used in early installations of Shuttle Loop. These rides are often not very tall, and usually achieve speeds of 60 mph (96 km/h). Flywheel Flywheel launches are used on some Anton Schwarzkopf designed shuttle loop coasters and Zamperla Motocoasters. A large flywheel is spun at high speeds and is attached to a cable that propels the train forward. Electric motor and spring tension Arrow Dynamics' Launched Loop coasters, which were popular in the 1970s and 1980s, use a powerful electric motor and tensioned springs to propel a launch car forward. The launch car pushes the train outward to a drop, and then returns to its position. After the train reaches the opposite platform, another catch car works the same way. An example of this is Irn Bru Revolution. Friction wheels Another type of launch is by friction wheels. The launch track consists of a series of horizontal tires that pinch the brake fins on the underside of the train. One example of this is the Incredible Hulk Coaster at Universal's Islands of Adventure.
