Return to the Mouse


As the Fall season settles in and the weather turns to more pleasurable temperatures, it's time to pack the bags and head to Orlando to pay homage to the Mouse - in the form of excessive amounts of hard earned dollars. Our previous trips demonstrated the capability of our accelerometer product line. The results of this trip combines synchronized data from an X6-1A accelerometer and a B1100-1 barometer to provide an enhanced appreciation of roller coasters.

Tower of Terror

First up is the Tower of Terror at Disney's Hollywood Studios. The rise and fall of the elevator is an obvious application of the B1100-1 barometer data logger. Below is a plot illustrating the change in height during the ride as well as the RMS g-force experienced during the ride. The Disney Imagineers were not lying when they promised 13 stories of terror. The barometric data, when converted to altitude measurements, shows a 129.2 foot travel for the elevator.

The Astro-Orbiter at the Magic Kingdom proved to be an interesting ride. This attraction whirls guests around in circles while allowing up and down height changes (the classic Dumbo ride themed with rockets). As part of the queue, guests are taken up an elevator to the boarding area (about a 22 foot elevation change). After being stuffed into the small compartment of the rocket, the ride spins guests at 10 times per minute. The spinning motion created a 0.2G centrifugal force. The surprisingly short ride elevated to a maximum of about 15 feet.

Splash Mountain

Br'er Fox and Br'er Bear send guests plunging over 50 feet into the brier patch as part of the Splash Mountain attraction.

Spaceship Earth

The iconic Spaceship Earth ride at EPCOT incorporates exceedingly uncomfortable plastic seats that keep guests awake during a slow journey through the origins and progress of modern communication. The X6-1A accelerometer was mounted to the ride car with double stick tape to ensure a consistent position throughout the ride. This allowed data analysis to calculate the pitch angle of the car during the ride.
