Helix is be a roller coaster with many
exciting elements, as you may guess from the video. The ride
starts in a high position, at the foot of the AtmosFear tower. During
the first part of the ride, the train uses the initial gravitational
energy, before reaching the first launch.
The launch uses electromagnetism: LSM - Linear Synchronous Motors - in
contrast to the hydraulic launch of the Kanonen roller coaster. This
technology may inspire a new interpretation of Einstein's first paper on
relativity "Zur Elektrodynamik Bewegter Körper" - "On the
Electrodynamics of moving bodies". A variable magnetic field in the
track pushes the magnets on the train. For the launch to work, the
change in magnetic field must change faster and faster, as the train
accelerates - in a "train accelerator". Of course, also the brakes are
magnetic, like the brakes in Kanonen.
The picture shows the accelerometer data during the testing in April
2014. The accelerometer was lying down on the seat to the right in the
first row. The numbers in the figure refers to the
photo in the blogg.
