A multi-launch roller coaster replaces the traditional single chain lift hill with multiple launch systems—LIMs (linear induction motors), LSMs (linear synchronous motors), hydraulic launches, or friction wheel drives—propelling the train to high speeds multiple times during the ride.
Instead of one slow climb storing potential energy, multi-launch coasters use sequential accelerations. Each launch adds kinetic energy, enabling:
| Type | Mechanism | Characteristics |
|---|---|---|
| LIM | Electromagnetic induction | Smooth, adjustable, lower maintenance |
| LSM | Synchronous magnetic | Precise, efficient, high acceleration |
| Hydraulic | Fluid pressure accumulator | Extreme power, complex maintenance |
| Friction Wheel | Tire-driven | Simpler, weather-sensitive |
Multi-launch coasters deliver signature attractions with marketable stats (speed, height, inversions) in smaller footprints than traditional mega-coasters—maximizing ROI and guest throughput.
