Inertial Drive Device Using FHM to Convert Variable

                      Angular Momentum into Linear Momentum

Purpose:
         The purpose of this device is to produce differential/off-set angular momentum thru rotary motion and centrifugal force. The centrifugal force is far greater during one-half of the rotation cycle than the other, thus producing a net linear directional force. Even though the masses describe a symmetrical closed loop during rotation, the magnitude of the centrifugal force over time differs significantly during the rotation cycle.

Device Description:
- The device consists of two main platters in a stacked system.

- Each platter is attached to a heavy fixed drive shaft that is attached to the top plate and bottom mounting plate by heavy roller bearings.

- Attached off-set on the main platters are two to four drive gear sub-platters with off-set masses, which makes each of them eccentrically balanced.

- The geared sub-platters are driven by a fixed gear that is mounted to the mounting plate by a flange that allows the drive shaft to pass through it to the mounting plate bearing.

- All gears are the same size and have the same number of teeth so that each sub-platter gear makes one rotation per revolution of the main platter.

- The eccentric weights are configured as in Fig. 4 to produce the desired effects.

- The bottom end of the drive shaft is attached to a conical mitre gear that is one of a set of four (can be expanded to six for two additional right angle sub-platter systems (two plane system).

- The conical mitre gears comprise a differential that produces counter-rotation in the two main platters.

- Two more conical mitre gears can be added for two additional right angle mounted sub-platter systems.

- One or both of the side conical gears are driven by a variable speed motor(s), but if additional sub-platter systems are added, the motors would drive the main drive axle.

- A more advanced device can have the off-set weights in the geared sub-platters able to move via solenoids from the hubs to the rims of the sub-platters, thus producing variable eccentricity in the platter-gears while in motion. In this configuration the device can be brought up to speed in a fully balanced condition, then gradually (and variably) have the eccentric flywheel condition engaged at varying levels of eccentricity (see Fig.4.b).

- It would also be interesting to see if substituting Neodium-Iron Boron magnets for the masses in this device could produce enhanced propulsion effects; i.e., produce rotating magnetic fields, which could  interact with static electromagnetic coils.

      Dual counter-rotating platter system with four sub-platters/gears that have an eccentric center-of-gravity and complete one rotation per revolution of the main platters. The following figure is of one platter from a stacked platter configuration:

This system can be expanded to include two or more platter subsystems at right angles to each other (3 planes: pitch, roll, yaw)

Fig. 4: Sub-Platter/Gear cg Positions / Momentum per Rotation of Main Platter - åmv1 = å mv2, but åma1 >> å ma2. Momentum is proportional to the masses distance from drive axle (Iw ~ r²) . 4a. - immovable /fixed cgs on sub-platters. 4b. - cgs move to center of sub-platters during ¾ of cycle, extend to rim of sub-platter during remainder of cycle. This would enhance the off-set momentum for 1/4 of the cycle while reducing momentum during 3/4 of the cycle. The shape of the mass-position track of this device exactly resembles the track of Tesla’s “Flying Stove” device.

Magnetohydrodynamically Driven Liquid and

Plasma Inertial Drives

INTRO:
        Directional inertial drives can be created by forcing conductive liquids (i.e., mercury, magnetic/ metal slurries, ferrofluids, super-fluids) or plasmas to counter-rotate in ovoid tube raceways that are both geometrically shaped and off differing diameter to create differential momentum via the Venturi Principle and varied angular momentum.   Propelling the liquid or plasma in such a device can be done by magneto-hydrodynamics, so that the only moving parts are the conductive liquid or plasma. Total momentum is conserved within such a system, but directionality is not; i.e., action momentum is more-or-less linear and central while reaction momentum is distributed as a series of radial vectors. Multiple paired tube arms are used in such devices. Such a device has a great advantage over a rigid mechanical system (designed for the same purpose) in that angular momentum and gyroscopic action are continuous and flexible (though varying) in such devices, plus there are little or no moving parts to impart friction or mechanically fail (no friction if a super-fluid is used).

OVOID / TOROIDAL DRIVE:
         The following schematic is of a gyroscopic/hydrodynamic device that uses a high velocity circulating conductive fluid to produce net linear directional momentum from cyclic changes in the angular momentum of the fluid. It consists of four (or other even number of) joined closed-loop ovoid /egg-shaped tubes that vary in diameter to produce different fluid velocities. A magneto-hydrodynamic coil drive is used to accelerate the fluid in the centrally conjoined tubes which narrow in diameter along the length of the mag-drive section. The accelerated fluid in each arm is then forced around a tight curve (that is still narrow in diameter) to impart maximum angular momentum to it. The fluid then decelerates as it enters the wider and more gradually curved portion of the tube ovoid and imparts reaction angular momentum radially around the larger curve loop. The fluid is then accelerated in the mag-drive section again, completing one cycle. Tubule bundles can be added to both the acceleration and deceleration sections of the ovoid to impart and maintain a laminar flow in the fluid (see Fig.2).  Bernoulli foils can also be added to the narrow curve section of the tube to further enhance angular momentum at that location.

FIGURE 2 - Two Arms of a Multi-Ovoid Device. High velocity and momentum occurs at the tops of the tubes due to mag-drive acceleration and a narrower tube; it then drops to lower velocity at the larger loop ends. Tubule bundles are positioned in the acceleration and deceleration parts of the tube to create laminar flow. Counter rotation of the fluid in paired tubes negates precessional forces in their rotation plane.

        Devices that use plasma instead of conductive liquids can also be driven by high gauss Lorenz Force, similar to that used in a Tokamak or particle accelerator . Such devices can exploit the full benefits/effects of the Critical Action Time (CAT) as mag-driven plasmas can be accelerated to high relative velocities in ultra-high energy/flux fields. The net desired effect of such devices is to create a higher dynamic linear effective mass at one end of the device and a lower effective mass at the other end [Critical Action Time µ Angular Momentum differential], thus creating a hypothetical directional field effect.

        The last schematic is of a device that is a geometrically shaped/distorted torus that circulates the conductive fluid or plasma at right angles to the torus (created by rotating Figs.1 or 2 thru 360°). This device is / can be completely surrounded by the magneto hydrodynamic propulsion coils. Such a device would have both properties of electro-magnetic force effects and inertial mass/ momentum.
