Catapult Launch on Roller Coasters: Instant Acceleration

How It Works

1. Train positioned on inclined launch track.
2. Flywheel or piston stores energy (hydraulic/pneumatic).
3. Release propels train 0→top speed in seconds.
4. Train transitions to main circuit.

Famous Examples

• Xcelerator (Knott's): 0–82 mph in 2.3 s (hydraulic).
• Top Thrill Dragster (Cedar Point): 0–120 mph in 3.8 s (pneumatic).
• Do-Dodonpa (Fuji-Q): 0–107 mph in 1.56 s (dual hydraulic).

Catapult launches deliver intense G-forces and adrenaline, defining modern "launched" coasters.
