Here is a description of
my science project:
My goal is to use gyroscopes to float a payload.
I plan to test my theory that one set of 4 gyroscopes can be kinetically leveraged against 4 other gyroscopes to create an independent internal center of mass that facilitates the transfer of angular momentum to linear momentum to float a payload.
My experiemnt does not violate "Conservation of Momentum" laws, as it uses a profound combination of oscillation thrusters, reaction wheels (momentum wheels) and levers to float its payload.
The experiment consists of 2 sets of 4 levers symmetrically connected at 8 hinged fulcrums which are fixed pivot points. These fulcrums support the load surface and are kinetically connected to 2 hub planes supporting the 2 sets of spoke levers. Each of the 8 spoke levers is equipped with its own motorized gyroscope on the outer end of the rimless spoke. Each spoke is supported midway by a hinged fulcrum leg extending from the payload surface above (or below) the levers.
The center of the device is comprised of 2 hub planes moving together and apart by a symmetrical one piston high torque engine. The 2 hubs are kinetically connected to the load surface by only these fulcrum hinges. Four hub ends of the spoke levers are kinetically connected to the upper hub plane. The other set of 4 hub ends of the spoke levers are connected to the lower hub plane. The hub planes are moved apart and together by the electronically cycled stroke one piston engine mentioned above. This causes the two sets of levers to move against each other.
As the gyroscope motors on the outer end of the spokes spin their corresponding gyroscopes and the hub planes push the two sets of levers against each other, a momentum is introduced at the hinged fulcrums. The movement of the levers transfers the momentum to the load surface by the supporting hinged legs. This second inertial force is created by the hub engine's independently self-contained opposition to the inertial effort of the 2 sets of four gyroscopes also moving against each other. The momentum created is harnessed and transferred to the load. The central opposition is then leveraged by the corresponding and relative resistance to the gyroscope's inertial force at the fulcrums. The independent hub stroke effort also leverages the 2 sets of opposing centrifugal forces at the shared fulcrum hinges.
Experiments with the direction and speed of the gyroscopes' spin will continue with future prototypes. For the sake of stability, it is suggested that the gyroscopes adjacent to each other have symmetrically opposite spins to neutralize their inclination to tilt when a load is applied.
Leveraged buoyancy is the means to the machine's proposed non-canceling properties. The opposing forces of the device are strategically designed to push the device away from the ground using a virtual or quantum stairway.
The lower set of gyros use strategic speed, direction and kinetically leveraged design to introduce a propulsion into the opposing force of the upper set of gyros.
A non-inertial retraction system is prior art for the DreidelSpoke :
Pneumatic Muscle Actuator (PMA)Webpage
"The Pneumatic Muscle Actuator (PMA) is a silicone tube reinforced with a braided Vectran fiber that is inserted between the cargo slings and the parachute confluence point."
"A stick trigger hanging beneath the platform strikes the ground and activates a generator that expands the actuator with a hot gas. When the actuator is inflated at about 20 feet before impact, its diameter increases while its length decreases by 35 percent, pulling the cargo up toward the parachutes and reducing the cargo's landing velocity."
I welcome any person's constructive input. And, of course a contribution for DreidelSpoke prototyping and research is always welcome. Please note that your contribution is not an investment.
Below is a top view and a closeup of the latest DreidelSpoke animation.
This version will use electromagnetic muscle actuators to cycle its push/pull drives.

Below is an earlier CAD drawing of the DreidelSpoke .
This version used a motorized slider crank mechanism to cycle its push/pull drive.

"If you give me a lever and a place to stand,
I can move the world."
