Woodward Effect (W-E) Requirements
  • The W-E describes the fact that inertial mass is
    generated by advanced retarded G/I spacetime
    cyclic disturbances between a local mass and all
    the rest of the mostly distant mass in the
    universe or Far Out Active Mass.
  • This Wheeler-Feynman Absorber interaction is a
    Radiation Reaction like spacetime-disturbance
    that is effectively instantaneous in nature.
  • There are three (3) main criteria that must be
    met AT-THE SAME-TIME locally to evoke the W-E.
  • 1 - The atomic ions in the local mass must be in
    an accelerated state (d-velocity or
    d-acceleration /dt).

3
Woodward Effect (W-E) Requirements
  • 2 - The time rate of change of mass density rho
    (r) must be non-zero. I.e., the accelerated
    mass dr/dt 0.
  • 3 - The changing mass densitys ions MUST be
    exchanging energy (dE/dt) with the
    semi-stationary ions in the Unit Crystal Cell
    (UCC).
  • Since E mc2, we can combine dE/dt with dr/dt and
    just track dr/dt, with the understanding that all
    mass energy flows (in both the positive and
    negative time senses) to ALL parts of the
    universe must be accounted for.
  • This means that to obtain the W-E, the ions
    dv/dt or da/dt, dr/dt and dE/dt in the mass, MUST
    ALL be non-zero and synchronized in the local
    frame in the appropriate manner.

PZT Ceramic Characteristics
  • Piezoelectric Lead Zirconate Titanate (PZT) A
    Perovskite Ceramic
  • In the perovskite unit cell, lead ions occupy
    the corners (A sites), oxygen the faces (X
    sites), and titanium/zirconium the octahedral
    voids (B sites).
  • The titanium and zirconium ions are smaller than
    the octahedral void and can be displaced by
    applying an electric field or mechanical load.
    This is how polarization occurs. The oxygen ions
    will be displaced in the opposite direction of
    the titanium/zirconium ions.
  • The maximum displacement allowed by the crystal
    structure is termed the polarization saturation.
  • Ferroelectric materials are those in which the
    polar axis of the crystal can be changed by
    applying an electric field.
  • The spontaneous polarization can be observed by
    the positioning of the Pb2, Ti4/Zr4, and O-2
    ions within a unit cell.
  • Pb2 is located in the corners of the perovskite
    structure which is of tetragonal symmetry. The
    dipole moment can be seen by the displacements of
    the O-2 and Ti4/Zr4 ions.
  • A PZT ceramic is made up of unit crystal cells,
    that make up crystal domains, which comprise
    micron sized single crystal particles that make
    up the ceramic material.

Titanium (Ti) ion and brown Zirconium (Zr) ions
in middle lattices. They and their surrounding
Oxygen (O) ions oscillate up an down, while the
more massive Lead (Pb) ions are relatively still.
Note that the four face oxygen ions move in the
OPPOSITE DIRECTION in relationship to the Ti or
Zr ions. This tends to cancel some unbalanced
forces.

of its travel at B D, but the exact position of

W-E Rotary Force Magnification
  • W-E exotic matter induced mass reductions can be
    used to produce propulsive Force (Newtons) by
    using Newtons 2nd law, F Mass x Acceleration
  • To maximize F, one needs to maximize M and/or A
  • If one momentarily imbalances a rotating
    flywheel, a net force can be produced.
  • Centripetal Force imbalances unbalanced D Mass
    x Rim Velocity2 / radius
  • Rim Velocity 2p x Revolutions/sec x Radius in
    meters
  • This assumes that when DM0, the rotor is
    balanced.

W-E Force Magnification
  • Centripetal Rim accelerations of 15,000-g
    (147,000 m/sec2) can be obtained for a 15,000
    rpm rate with a moment arm radius of 0.06 meters.
  • Sanity check Current Smart Artillery Shells
    (105 or 155mm diameters) have imbedded micro-CPU
    GPS receivers that survive linear accelerations
    of up to 15,000-g for 10 milliseconds and
    concurrent rotational rates of 300 revolutions
    per second, which implies constant radial
    accelerations of up to 19,000-g.

40
W-E Force Magnification-2
  • Conclusion The 15,000-g Rotary UFG assumptions
    are reasonable and doable by placing the mass
    fluctuation at the rim of a 15,000 rpm flywheel.
  • If we have a W-E induced DM of 0.10 gram in a
    UFG, the unbalanced force 0.00010 kg x 147,000
    m/sec2 14.7 Newtons or 3.30 lbs
  • If DM 2.22 grams, F 0.0022 grams x 147,000
    m/sec2 323.4 Newtons or 72.8 lbs.
  • If DM 10.0 grams, the unbalanced force 0.010
    kg x 147,000 m/sec2 1470.0 Newtons or 330.5
    lbs.

W-E Force Magnification-3
  • You might now ask how do we keep the rotating
    imbalanced force pointing in a single and usable
    direction?
  • Attach multiple UFGs on the outside RIM of the
    flywheel and commutate them on and off with
    microseconds-to-milliseconds switch timing as
    required to keep the generated imbalanced force
    vector pointing in the desired direction.
  • Then use two (2) counter-rotating flywheel-UFG
    assemblies together to nullify the flywheels
    torque.

44
Linear Rotational UFG Development Issues
  • Consistent PZT generated mass-reduction signal
    over time. Tested PZT ceramic materials have
    detrimental time, temperature and power history
    dependent characteristics, which are obtained
    only though very extreme operating conditions.
  • Engineering 200-to-500 kHz Ultrasonics systems
  • Development of Closed Phased Locked Loop Tuning
    of PZT mass reduction resonant frequency.
  • Increase of PZT mass-reduction signal per unit
    input power. (PZT mass-reduction increases with
    the square of the operating frequency input
    power.)
  • Rotational drive electronics rotor integration.
