ABSTRACT
This Angular Momentum Engine uses Servo Motors, con
nected to a planetary gearbox, to spin-up a high speed inertia
load, a ‘point mass’ spinning horizontally around a vertical
axis, like the ball on the end of a string.

changing direction. Accelerations are caused by net forces on
an object. In the case of an object moving in a circular path,
the net force is a special force called a centripetal force.

RELATED U.S. PATENT DOCUMENTS
APPLICATIONS
[0001] This patent application claims a Continuation in
Part to application Ser. No. 13/199,849 ?led Sep. 9, 2011 Title
of Invention Angular Momentum Engine.
BACKGROUND
[0026] From the perspective of Man ‘A’ on the train, he is
moving east at a constant speed of 3 feet per second in the
opposite direction the train is moving and stationary relative
to Man ‘B’ standing at rest, motionless on the train platform.
[0027] From the perspective of Man ‘B’ on the train plat
form, Man ‘A’ on the train is stationary relative to him, and the
train is moving at a constant speed of 3 feet per second to the
west.
[0028] In this patent design, the ‘planetary gearbox’ and
‘point mass’ are accelerated to a constant relative rotational
[0002]
State of the art Motion Control System and equip
ment are used in controlling the Angular Momentum and
positioning of a ‘point mass’ rotating horizontally around a
vertical axis to change the rotating ‘center seeking’ centrip
etal force to a linear ‘center seeking’ centripetal force. FIG. 6
[0003] This invention uses this linear ‘center seeking’ cen
tripetal force to accelerate a vehicle such as a commercial
automobile. The design is new relative to how the forces are
created and used but the technology has been solidly
embraced in the laws of physics for many decades.
[0004] While it is common place for an engine to create a
force to push a vehicle, or an equal and opposite reaction to
propel an aircraft, this linear ‘center seeking’ force pulls the
vehicle. Such changes to normal are exhibited throughout the
speci?cations and therefore requires a perspective relative to
a changing environment.
velocity counter-clockwise. The ‘point mass’ is then acceler
ated to the same constant relative rotational velocity but in the
opposite direction of the gearbox, clockwise. FIG. 1 FIG. 2
[0029] From the perspective of the ‘point mass, it is rotating
clockwise at a constant speed but in the opposite direction the
gearbox is rotating and stationary relative to an ‘Observer’
standing at rest, motionless.
[0030] From the perspective of an ‘Observer’ the ‘point
mass’ is stationary relative to him, and the gearbox is rotating
at a constant speed counter-clockwise.
[0031]
The ‘point mass’ is now moving at the same speed
counter-clockwise as it is clockwise and therefore to a sta
tionary observer the point mass appears not to be moving
relative to him. This positioning of the relative velocity and
relative motion of the ‘point mass’ to a stationary reference
point results in the ‘center seeking’ centripetal force being
changed from rotational to linear.

BRIEF DESCRIPTION OF THE INVENTION
[0032]
This change of the ‘center seeking’ centripetal force
from rotational to linear will be referred to as the ‘spin-up’ in
future references.
[0033] A point mass is used in each system, ‘Point Mass 1’
in FIG. 1, ‘Point Mass 2’ in FIG. 2 to balance the rotational
forces. FIG. 3 depicts an overlay of FIG. 1 and FIG. 2 illus
trating the two point masses are 180 degrees apart at all times
and also that the ‘point masses’ rotate in the same direction
whether their motion is counter-clockwise, clockwise, or at
rest relative to a stationary reference point during spin-up.
[0034] Balancing the rotational forces allows the system to
spin-up vibration free and also provide a neutral position after
spin-up where the net linear ‘center seeking’ forces are bal
anced. FIG. 5a
[0035]
This balancing of forces is needed during times
when the vehicle is stopped, an accelerating force is not
required, or when the vehicle is on a downhill incline. Pro
viding full to partial power is as simple as moving the ‘point
masses’ to the power position.
[0036] ‘Point Mass 1’ and ‘Point Mass 2’ move a maximum
of 90 degrees to apply full forward or reverse power. Mini
mum power is 1 degree, maximum power requires a move
ment of 90 degrees as illustrated in FIG. 5b, FIG. 50.
DETAILED DESCRIPTION OF INVENTION
[0037]
The planetary gearbox is utilized in changing the
relative velocity and relative motion of the ‘point mass’ to a
stationary reference point.
[0024] This invention changes rotating ‘center seeking’
The synchronous spin-up applies a counter-clockwise torque
centripetal force to linear ‘center seeking’ centripetal force
simply by changing the relative velocity and relative motion
to the ‘planetary carrier shaft’ by Servo Motor 1 & 3 and to the
of a ‘point mass’ to a stationary reference point.
[0025] As an analogy Man ‘A’ sitting on a train while its
leaving the train station is accelerated to a constant speed of 3
feet per second to the west. He stands up and walks at the
same constant speed of 3 feet per second, but in the opposite
(ring, planet, sun) of the planetary gearbox which results in
direction to the east.

gear is increased synchronously from —3000 to —4000 rpm.
The addition —1000 rpm to the ring gear using a 1:3 ratio
speed increaser gearbox, moves the ‘point mass’ to the same
of high centripetal forces generated from the product of a
relative rotational velocity, but in the opposite direction of the

minute with a 50 foot radius. As indicated above the centrip

[0039] The ‘point mass’ is now moving at the same speed
counter-clockwise as it is clockwise and therefore to a sta
tionary observer the ‘point mass’ appears not to be moving
relative to him. This positioning of the relative velocity and
relative motion of the ‘point mass’ to a stationary reference
point results in the ‘center seeking’ centripetal force being
changed from rotational to linear.
[0040] The centripetal force generated is the result of its
mass><velocity2/radius. The centripetal force calculation is
small mass at high revolutions per minute with a 6 inch radius,

used to control the point masses movement from neutral for
minimum to maximum power. A movement of 1 degree for
minimum power to a maximum of 90 degrees for full power.
On a ‘simple planetary gearbox’ when the planet is
held and the power input is to the ring gear, power output is to
the sun gear, rotational speed is increased and rotational
torque is reduced. The rotational direction power output is in
the opposite direction of the drive member. FIG. 4
[0042] This patent design has only one change to this
simple planetary gearbox outlined in FIG. 4. In a simple
planetary gearbox the carrier is held stationary at 0 rpm while
in this Patent Design the carrier is held stationary at —3000
rpm in this example. FIG. 5d Increasing the rpm to the ring
gear above —3000 rpm to —4000 rpm, with a 1:3 ratio speed
increase gearbox, results in rotational speed being increased,
rotational torque being reduced, and the rotational direction
power output in the opposite direction of the drive member
identical to a simple planetary gearbox as shown in. FIG. 4
FIG. 8
[0043] To a stationary observer looking at a ‘simple plan

a stationary observer looking at this ‘patent design gearbox’
the ‘point mass’ appears to be stationary but is also rotating at
+3000 rpm. FIG. 5e

1. This invention ‘Angular Momentum Engine’ changes
rotating ‘center seeking’ centripetal force to linear ‘center
seeking’ centripetal force.
This change in force as indicated in [0035] is accomplished
by changing the relative velocity and relative motion of
a ‘point mass’ to a stationary reference point.
The linear centripetal force generated in this ‘Angular
Momentum Engine’ can vary as the centripetal force
[0035] is a product of the mass times the velocity
squared divided by the radius.
When these forces are used in pairs [0036] the ‘point
masses’ can be used to provide a neutral position where
the centripetal forces are balanced and also provide
minimum to full power, forward or reverse, by moving
each ‘point mass’ plus or minus 1 to 90 degrees from the
neutral position.
The linear centripetal force [0035] can be used to power
land, sea, as well as space vehicles.
This design allows the variables, the point mass, point mass
velocity, radius of the point mass arm, pulley ratio, and

This design allows the variables, the point mass, point mass
velocity, radius of the point mass arm, pulley ratio, and the
tion from a few pounds to millions of pounds of Cen
gearbox ratio to be increased or decreased to ?t the desired
centripetal force needed for a speci?c application.
[0045] If you double the point mass or radius the Centrip
etal force doubles. If you double the speed the Centripetal
force quadruples, Forces from a few to millions of pounds of
centripetal force canbe generated. FIG. 9 illustrates examples

Doubling the mass or radius doubles the Centripetal force,

current.
