Concept
Accelerator Coaster
Résumé
An Accelerator Coaster is a hydraulically launched roller coaster model from Intamin. The model usually consists of a long, straight launch track, a top hat tower element, and magnetic brakes that smoothly stop the train without making contact. The technology was developed by Intamin engineers as an alternative to electromagnetic launch systems, such as the Linear Induction Motor (LIM) and Linear Synchronous Motor (LSM), that are found on earlier launched roller coasters like the Flight of Fear and The Joker's Jinx. Unlike the earlier linear induction motors, the Accelerator Coaster's launch system exhibits constant acceleration and is capable of reaching greater speeds.
Accelerator Coasters with the top hat element are known to perform an occasional rollback – when the train is unable to complete the top hat element and rolls back to the starting point – which can occur due to a number of different factors. Despite this, Accelerator Coasters have a great track record for safety and are extremely power efficient, especially compared to older technologies such as the classic chain lift found on most roller coasters. Formula Rossa, the world's fastest coaster, and Kingda Ka, the world's tallest, are some of the most well-known installations around the world.
Despite these world-record setting achievements, Accelerator roller coasters have been infamous for their long terms of mechanical issues with its launch. Examples of these being Xcelerator at Knott's Berry Farm or Top Thrill Dragster at Cedar Point and as of 2022, Accelerator Coasters are no longer being produced.
An Accelerator Coaster's launch system operates on the same basic principle as a Super Soaker, but on a much larger scale. The coaster's power source is several hydraulic pumps, each capable of producing . These pumps push hydraulic fluid into several accumulators. These accumulators are divided into two compartments by a movable piston, one side filled with hydraulic fluid and the other with nitrogen gas. The nitrogen is held in large tanks directly beneath the actual accumulator.

List of roller coaster elements
Roller coaster elements are the individual parts of roller coaster design and operation, such as a track, hill, loop, or turn. Variations in normal track movement that add thrill or excitement to the ride are often called "thrill elements". A banked turn is when the track twists from the horizontal plane into the vertical plane, tipping the train to the side in the direction of the turn. Banking is used to minimize the lateral G-forces on the riders to make the turn more comfortable.
Thorpe Park
Thorpe Park Resort, plus connu sous le nom Thorpe Park, est un parc d'attractions situé dans le village de Thorpe entre les villes de Chertsey et Staines-upon-Thames à Surrey, Angleterre. Il appartient et est exploité par le groupe Merlin Entertainments et contient des attractions, un hôtel thématique, divers événements et contient également Stealth, la plus rapide montagne russe du Royaume-Uni. Après la démolition du domaine Thorpe Park en 1930, le site est devenu une gravière gérée par Ready Mix Concrete (RMC).
Montagnes russes lancées
Les montagnes russes lancées (en anglais : launched coaster) sont un type de montagnes russes qui ont la particularité de projeter leur trains à la place des traditionnelles remontées à chaînes. Les mécanismes de ce type de montagnes russes restent multiples (LSM, catapultage, LIM, hydraulique, pneumatique). vignette|200px|droite|. Freeze à Six Flags St. Louis.
