Accelerator (roller coaster)
An Accelerator roller coaster is a type of high-speed launch coaster characterized by its use of a powerful launch system, typically hydraulic, to rapidly propel trains to top speeds. This launch system differentiates them from traditional roller coasters that rely on a lift hill to gain initial momentum.
Characteristics:
- Hydraulic Launch: The hallmark feature of Accelerator coasters is their use of a hydraulic launch system. This system utilizes powerful hydraulic motors and cables to quickly accelerate trains from a standstill to their maximum speed in a matter of seconds.
- High Speed: Accelerator coasters are known for their intense acceleration and high top speeds. These speeds often exceed 100 miles per hour (160 kilometers per hour), providing riders with a thrilling and intense experience.
- Tall Structures: Many Accelerator coasters feature towering structures, particularly the top hat element, which involves a steep ascent and descent. These structures contribute to the overall height and prominence of the ride.
- Compact Layout: While some Accelerator coasters have sprawling layouts, many feature relatively compact designs. This design choice allows for a focus on the launch and immediate high-speed elements.
- Airtime Hills: Though primarily focused on speed and launch, some Accelerator coasters incorporate airtime hills, which provide brief moments of weightlessness.
- Over-the-Shoulder Restraints (OTSR): Due to the high speeds and intense forces involved, Accelerator coasters typically utilize over-the-shoulder restraints to ensure rider safety and security.
- Launch Track: A dedicated launch track is a critical component, providing a straight and level section of track where the train is accelerated.
Operation:
The operation of an Accelerator coaster typically involves the following steps:
- Loading: Riders are secured into the train with over-the-shoulder restraints.
- Launch Preparation: The train moves into position on the launch track, and the hydraulic launch system is prepared.
- Launch: The hydraulic launch system engages, rapidly accelerating the train to its top speed.
- Circuit Completion: The train navigates the remainder of the track layout, which may include hills, turns, and other elements.
- Braking and Return: The train enters a braking section to slow down and return to the station for unloading.
Manufacturers:
Intamin AG is a prominent manufacturer of Accelerator roller coasters, having developed and installed many of the most well-known examples of this ride type.
Significance:
Accelerator roller coasters are a popular attraction at amusement parks and theme parks worldwide, offering a unique and thrilling experience for riders seeking intense speed and acceleration. Their innovative launch systems and impressive speeds have made them a significant part of the roller coaster industry.
