Gyro-X Update
Including Details of the Tuscan Gyro-Stabilized, Half-Track, Trail Bike

Several people have written to me in recent months about the Gyro-X project, adding their knowledge and observations, for which I am very grateful. I have edited their comments for presentation purposes, so that they can be shared with others who are interested in this subject. -- Stephen Cobb

Tuscan -- Gyro-Stabilized, Half-Track, Trail Bike

We learned about this fascinating off-shoot of the Gyro-X project from Richard R Fuller of Jacksonville, Florida. Richard's father was one of the founding associates with Gyro Transport Systems (GTS). His name was Richard H. Fuller and he was the purchasing analyst for them. The younger Richard Fuller contacted us while searching the web for material on GTS which until very recently he thought was called Tuscan something. He was only 14 when the company started in Salt Lake City, Utah. He reports that within two years the company was disolved, ending hopes of moving to Ponce, Puerto Rico to build the manufacturing plant.

However, during that time, when the company was located in Northridge, he met Alex Tremulys, Tom Summers, Al Crane, and Ed Davis. When the company dissolved, Richard's father was offered a job at American Airlines and the family moved to Tulsa. But the younger Richard kept a lot of materials, including an 8x10 glossy of the Gyronaut X-1 signed by Alex Tremulus to his father, and the product brochure for the Tuscan. Richard kindly scanned the brochure for display on the web.

The Hellfire Connection

A considerable amount of very useful background information was supplied to me by Jerry Goldstein, who also filled in some details of the Gyro Hawk kit car. Here's what Jerry told me:

"What happened to the Gyro-X was relayed to me by Tom Summers when I tracked him down in 1991, after realizing the need for a small, enclosed and stabilized motorcycle. An old timer had seen the Science & Mechanics article and I researched it. I found Alex Tremulus just before he passed away and through his wife was able to get in touch with Tom Summers. I visited Tom and we talked about the article.

"Tom had his own gyroscope company in the fifties, and contracted with the US Forest service to build several prototype mechanical mules for carrying ore from copper mines located on US forest preserves that were remote and inaccessible except by pack mules. The idea was to build a mono-trak vehicle that could access the mine through the wilderness without having to build roads through the prime forest. Tom developed several testbeds, generating considerable interest and attracting Alex Tremulus and a group of investors from the University of Utah who wanted to build a prototype passenger car using Toms designs.

"An investment group was formed and a prototype built. The car was built in Los Angeles. The body design is by Alex Tremulus who also styled the Ford Thunderbird and the Ford Gyron (note: we plan to add more about the 2-wheeled Gyron soon).

"The car prototype actually used the powerplant from one of the ore mules which belonged to the US government. Tom maintains that the investment group attempted to steal his patented designs and go ahead on the project without compensating him. He sued the group and effectively killed the project, but it left him ruined financially.

"He was retired from Tally Corporation in 1988 when it was acquired by Hughes after old man Tally died. The new owners found Tom " wandering the halls" and put him out to pasture, not realizing he was the foremost inertial guidance engineer of the post WWII era. Toms design of the Hellfire missile guidance system is still in use today. Tom tried unsuccessfully to bring the gyrocar to reality several times over the period from 1968 until his patents expired some twenty odd years later."

Jerry feels that Tom is something of a national treasure, and an unsung hero. "He invented the vertical sensing device that became the key to the success of the Norton bombsite in WWII. The Germans tried to entice him into sharing his information with them but the U.S. Gov't put Tom to better use here. Tom had his own gyroscope company in the '50s and was a pioneer in the field of inertial guidance. He held over 100 patents. Tom worked for Tally corporation in the '70s, perfecting the guidance system of the Hellfire missile for which Tally was a prime contractor. His effort to produce the gyro vehicle began with the ore carrying "mules" that provided the powerplant and gyro for the car that appeared in Science and Mechanic in 1968."

Several readers of this page have suggested that the Tuscan was not in fact gyro-stabiized. After considerable reflection I agree that it is unlikely the model pictured here used a gyro. However, we are told in the Science and Mechanics Gyro-X article that Gyro Transport Systems was working on a gyro-stabilied trail bike for the US Forest Service and I'm speculating that it was a modified version of the Tuscan. As always, I am happy to hear from anyone who can shed light on these machines. Email me as webbloke at cobb dot com or leave a comment at the gryocar blog.

Lit Motors

lit

Lit Motors Inc. is a San Francisco-based company that designed conceptual two-wheeled vehicles, including a fully electric, gyroscopically stabilized vehicle.[1]

Founded by Daniel K. Kim in 2010, Lit Motors designed concepts for two-wheeled vehicles with a focus on innovative technologies. They have released information about two projects: the AEV (auto-balancing electric vehicle) often referred to as the "C-1" and the Kubo cargo scooter. The inspiration for Lit Motors came to Kim in 2003, when he was nearly crushed by a chassis while manually assembling a bio-diesel Land Rover Defender 90.[2] Kim decided to "chop a car in half" to create what is now the C-1

https://en.wikipedia.org/wiki/Control_moment_gyroscope#Single-gimbal

Single-gimbal -- The most effective CMGs include only a single gimbal. When the gimbal of such a CMG rotates, the change in direction of the rotor's angular momentum represents a torque that reacts onto the body to which the CMG is mounted, e.g. a spacecraft. Except for effects due to the motion of the spacecraft, this torque is due to a constraint, so it does no mechanical work (i.e., requires no energy). Single-gimbal CMGs exchange angular momentum in a way that requires very little power, with the result that they can apply very large torques for minimal electrical input...

Exclusive: This Is the Gyro-Stabilized, Two-Wheeled Future of Transportation

...In its current form, the two gyros each put out 266 pound-feet of torque as they spin, keeping the C1 upright no matter the speed or angle. In final production form, the combined force of the pair of gyros will max out at around 1,300 pound-feet, enough to keep the C1 vertical while stopped, at steady-state cruising and planted to the road at a maximum lean angle of 45 degrees.

The ability to simply pull the entire gyro setup from the chassis is a design decision that will make it to production, allowing the C1 to be serviced quickly and efficiently, much like the battery pack mounted to the floor of the Tesla Model S. It also helps when something goes awry during its maiden voyage in the eager hands of someone outside the Lit Motors studio...

us45820439
Gyro stabilized remote controlled toy motorcycle having good stability and control without using ground contacting auxiliary wheels or the like. The motorcycle comprises a chassis supporting a fixed angle rear wheel drive and associated motor and a castered front wheel. A gyro wheel having an axis nominally parallel to the axis of the rear wheel is mounted in a gimbal with a vertical axis in the forward part of the chassis and connected to the front wheel fork and post to turn the front wheel responsive to the rotation of the gimbal relative to the chassis. The chassis further includes a radio receiver, battery power and a steering device, such as a motor and slip clutch for torquing the gyro wheel gimbal. To turn in a first direction the gyro gimbal is torqued in the opposite direction, initially causing the front wheel to also turn in the opposite direction. As the motorcycle and the gyro lean into the turn, a correcting torque is generated by the gyro and caster of the front wheel, overcoming the initial steering torque to maintain the proper steering angle and balance for the motorcycle. Various embodiments are disclosed.
