Flywheel launches
Store energy in a spinning mass, then dump it into the train in one burst — classic hydraulic acceleration feel.
Some launch systems spin a flywheel to store energy, then transfer it hydraulically to a catch car that tugs the train.
The guest feels a short, sharp acceleration — famous on early hydraulic launchers.
Energy storage decouples the instant power demand from the park grid, but mechanical wear and weather can affect consistency.
Modern parks increasingly use linear motors, but flywheel-hydraulic DNA still shapes enthusiast expectations for “launch coasters.”
