DEAN DRIVES AND DAVIS MECHANICS, Inertial Propulsion and the Manipulation of Time in Symmetrical Systems © 2007, 2017


"The Dean inertial propulsion impulse engine is not amiable to a quick and dirty analysis; it is a dynamic and complex multi-dimensional space drive."

The reaping of centrifugal force from rotary motion for propulsion has stumped us humans for centuries. The paradox, it seems, lay in the way we tend to think about our world at large. In the past, inventors and engineers generally thought in terms of how to make it work by manipulating mechanical matter and energy (preferably electricity). The quest is, and always was, to generate unbalanced impulses from a system that is physically symmetric.

Dr. Davis model of a Dean Drive

Dr. Davis theoretical model (circa 1962) of a unidirectional thrust engine or unbalanced oscillator. A = Oscillator, sine wave or saw-tooth – waveform may be critical. B = Long time signal path. C = Short time signal path. D = Clutch, timing is critical. E = Clutch. F = Frame.

But the enigma of inertial propulsion had a simple solution all along. Maybe just knowing how to do something is not as important as knowing when to do it. Norman L. Dean could think in multiple reference frames and found this elusive force by manipulating time within the cycle of a spinning rotor. But first he had to convert the rotary motion into oscillations. You can use any rotary-based oscillator, even the subtle oscillatory action of the atom may be “rectified” into an unbalanced force simply by diddling with the “fixed vector” t – the flow of time.

Buehler Drive on which the Dean Drive is based

A Fundamental Anomaly: This mechanical oscillator is a balanced system called a Buehler drive on which the Dean Drive is based. It was used in the 1920s as an industrial vibrator to shake fruit and nut trees. It converts 360° rotary motion into a powerful 180° bi-directional force. Why does the carriage swing with the rotors instead of away as would be predicted by Newton’s third law of motion (action/reaction)? The reason: Since the rotors are counter-rotating, side forces are cancelled out and the carriage swings towards the sum of the rotors angular momentum – demonstrating centrifugal force can exist apart from a centripetal.

How do you change the flow of time?

Let’s say your estranged uncle died and left you with 100 brand new cars and they were just delivered to your backyard. You drive one car three miles to a dealer, haggle for a bit, then sell it for a pure profit, but you have to walk back home. You drive another car to the same dealer, haggle, and sell again for a profit and walk back home. You repeat this cycle until you have sold all your cars. By then you have enough money to move to a new home.

Making a Dean Drive




Channeling Rotary Motion: The second step to making a Dean drive is to suspend the rotor axle creating a second inertial frame operating within a third inertial world frame.


That is how a Dean drive works. Your car lot may be likened to a source of electricity. You are the eccentric rotor in a Dean Drive that is shifted when you save time by driving to the dealer. To your neighbor, who is now quite sure you’re insane, your cycle of driving away a new car and walking back remains constant. But to you, time is saved driving to the dealer, you spend that extra time in haggling out a profit, then spend an equal amount of time you did in driving and haggling on your return walk back home.

Cancellation and addition forces hold true for both horizontal and vertical carriage systems.

The system is still balanced, only the time varies within that system. It’s a question of different inertial frames of reference. Likewise, the Dean drive converts energy – from electricity (your car lot) into rotary motion (round-trip) then into an oscillatory action (repeated round-trips), then shifting of the rotor (your drive), the clutching of the rotor (the haggling) to create centrifugal force (profit). The walk back home is within new space.

Levitating Loafers and Cool CAT Fission

As we have seen in any given system, including electromagnetic, action and the subsequent reaction are not simultaneous events. As such, there are time delays between any and all relationships in the phenomenal world. This critical action time or CAT as coined by the late Dr. William O. Davis is a real phenomenon that forces us to take a long look at classical mechanics and even the premise of time. It is during the CAT we can take advantage of motion and do things our ancestors only dreamed of.

The Three Forms of Motion

Linear Motion



Rotary Motion



Dean Drive surge


Mass in linear motion has acceleration vector in opposite direction of the velocity vector

Mass in rotary motion has acceleration vector perpendicular to velocity vector

Mass in rotary surge has acceleration cyclically reversed lagging another 45° from rotary velocity vector

Periodic exploitation of closed systems has countless applications not only in motion, but also in thermodynamics and quantum mechanics. Anyone who’s played “hot potato” knows there’s plenty of time to pass it off onto some unsuspecting player before getting burned because that motion occurred within the CAT. This implies there’s sufficient time to keep matter near absolute zero for efficient super-conduction, or to produce electromagnetic super-storage batteries by taking advantage of matter’s delayed reaction to applied energy.

Why all the fuss to develop an engine that’s not suppose to work in a Newtonian universe? If inertial propulsion becomes fully developed, it would have many important advantages:

1. Inertial propulsion has proven to be 20 times more efficient than conventional locomotion.
2. It runs on electricity, our most convenient form of power, making it safer.
3. Fewer mechanical parts than automobiles, planes or rocket engines – also making it safer.
4. Extends the life of automobiles by eliminating tires, roads and road vibration.
5. Efficient tractors and farming equipment because friction is not wasted on turning tires.
6. Propeller-less and rudder-less boats and submarines for super-efficient water travel.
7. Requires minimal lubrication.
8. Has vertical –take-off and –landing capability and can fly interplanetary.
9. Extend satellite life.
10. Quiet, convenient, clean, and inexpensive.

Norman Dean’s revolutionary impulse drive has applications other than propulsion. The shifting of inertial frames, along with the application of William O. Davis’s inertial delay times may allow us to:

1. Produce recoilless pile drivers, jackhammers, and mining equipment.
2. Employ spatial anchors and spacesuit maneuvering.
3. Develop efficient super-conductors.
4. Store huge amounts of electricity in batteries.
5. Generate flat artificial gravity (AG) panels heavier than 1 g.
6. Focus AG generators for use as tractor beams.
7. Molecular weld any material to any other material with inertial compression (IC).
8. Build “infinite mass” dynamos using IC for the generation of electricity.
9. Create a multitude of other well-spring technologies yet to be realized.

In the field of quantum mechanics we may someday build solid state inertial propulsion engine wafers that levitate simply by applying a voltage to stretch electron orbits on the topside of the substrate.[9] Davis Mechanics has already shown in closed systems, time – the t in calculus, is not a fixed entity like some stone monolith in the sky.[10] Dr. Davis's observations on matter and motion means that someday we may also generate electricity from machines that repeatedly impact atomic nuclei faster than its ability to react, creating a “cool fission” of sorts.

Solid-State Dean Drive principle

The Wayne Burnett Drive which he called "Quantum Radial Vectoring" would entail knocking-up electrons of certain materials into a higher orbit on one side of the atomic nuclei only. Forcing electrons to jump into biased quantum states in a solid material may be done by using laser, nuclear, or ideally, high voltage. If we could pulse a very high dc voltage at a very fast rate, we could stretch the outer electron shells from their relatively concentric orbits once every atomic cycle. This means using extremely high frequencies. If the capacitive load on the material holds without letting the circuit actually conduct electricity (high dielectric strength), the electrons will pull on the nuclei and affect lift on the applied substrate.

We already change the flow of time on a daily basis in electromagnetic systems whenever we modulate a radio wave, shine a laser beam, microwave a hot dog, or pump out a radar pulse. These are monopole systems. Manipulating time in machines that could power hovercraft, saucercraft or other aerospace systems could take us to the edge of the solar system - not in years, but weeks - and may even solve the energy crisis.

Norman Dean’s Patent #2,886,976

Norman Dean’s Patent #2,886,976 of his electro-mechanical inertial drive has intrigued millions for decades, so why hasn’t someone built a flying machine based on its design before now? The problem, as it turned out, was patent rights protection: Dean laid out his art so skillfully that without extensive research, even the most imaginative engineer could not deduce all the variables. For example, what are – and how do you harmonize – the proper shifter timing, clutch timing, stroke length, rotor mass, spring tensions, and the placement of slider switches used to synchronized multiple carriages with rotor cycles (a problem when the system runs for more than a few seconds)?
