The best place to get your first look at new theme park attractions often lies within the black and white line drawings on a federal government website. That's where you will find patent applications for intriguing new ride systems, such as Disney's proposed design for a roller coaster with a moving ride vehicle.
Wait a minute, I hear many of you asking, a patent application? For that? Don't plenty of roller coasters have ride vehicles that rotate as they move along the track? Well, you're right. But with patent applications, the how matters much more than the what, and the way that Disney proposes moving its coaster seats is what this patent is all about.
Disney's application, entitled Roller Coaster With Passenger Compartment Motion Powered Through Stored Onboard Energy, submitted April 13, 2017 but just published yesterday, describes a system to power the rotation of coaster vehicles on the track. Disney's system would use energy storage units mounted under the seats that would be charged by elements along the track.
The patent application explains that some existing coasters are able to rotate due to a busbar system that allows their cars to draw power on the track. But those systems aren't effective in corners or steep sections where the cars are moving rapidly, Disney said. From Disney's patent filing:
There remains a need for a new gravity-based roller coaster design that allows a passenger compartment to be provided motion, including yaw, in addition to its travel along the [direction of travel] defined by the track. Preferably, these roller coasters would facilitate maintenance and provide the motion in any section of the track including corners and areas where vehicles are traveling at higher rates of speed while falling due to gravity (or stored potential energy being converted into kinetic energy) and where it is impractical to provide bus bar systems.
The present description addresses the above problems by providing a roller coaster (or coaster-type ride system) in which a vehicle is configured with a drive system for providing motion to a passenger compartment relative to a chassis rolling along a track. The drive system is powered through... one or more onboard storage devices such as batteries, capacitors, supercapacitors, and the like. For example, the passenger compartment may be caused to move... to the left or right from a load/unload position to cause the passengers to face show or visual display features along the ride path....
Opportunity charge stations are provided in one or more sections of the track to recharge the onboard storage devices (such as with a capacitor charging plate in an unload/load station and with a bus bar strip in linear portion of the gravity-based ride sections), and the motion occurs in other sections of the track such as in curves or steep gravity-based ride sections of the track where connection to a bus bar or the like would be difficult and/or costly to implement and maintain.
Here are a couple of those line drawing illustrations of the concept:
So where will see this proposed system in action? This appears to be the best fit yet for the "yaw coaster" in Epcot's upcoming Guardians of the Galaxy ride. (Better than the last patent we saw that fit the same moving ride vehicle on a track concept.) The rotating motion enabled with this system should confirm that this thrill ride will maintain a strong linear visual narrative in addition to the typical coaster thrills.
Putting the moving platform on top of the coaster track distinguishes this ride system from Universal's Harry Potter and the Escape from Gringotts, which essentially placed its motion base units under the coaster track in certain locations. If you really want to dive into the tech, take a look at Universal's patent application for the ride system on its Gringotts coaster.Tweet
