Gravity ... Lord of Light:
Matter vying for the same space.
Consciousness IS the space.
Matter and space support each other
Like a dream void of substance,
 Or a fragile bubble,
Held apart only by a breath.

How to lose weight without throwing away the ship
– or the passengers

Rockets must lose 90 percent of their weight in fuel just to thrust the ship into orbit. Sometimes they lose human life. Are there other ways to do this without the waste and risk? Dean built a centrifugal force engine that lost 5% of its weight while running on a floor scale.[10] According to many physicists, even that slight weight loss would have been enough to have made us a space-faring race. So why aren’t we walking on the Moon and Mars today thriving with an interplanetary economy?

Sadly for Dean and the rest of us the political atmosphere of the 1950s, and resistance from the scientific community enchanted with the fireworks of rocket propulsion, grounded the Dean Drive.[11]

Centrifugal force from a 3-frame system

Centrifugal force from a three frame system: Taking advantage of the third derivative effect.

The Reciprocating Impulse Drive (RID)

Inertial propulsion engine E-8 is a two-cycle, 10 Hz reciprocating impulse drive (RID). It weighs 40 lbs and loses over 27 lbs while running on a floor scale (two different brand-name bath scales) without ejecting mass - using just 160 watts of power. This is a steady weight loss, not a bouncing scale or resonating dial effect, from a dependable centrifugal force engine that will not fly apart. Though my earlier inertial propulsion prototypes run horizontally using “stick-slip” (friction as a back-stop) because they are single-cycle units (E-4 and E-6), a multiple-cycle unit like RID can overcome its inertia vertically because there is no time for “slip”. Also, in-line spring-loaded floor scales have no “stick” to them. To top it off, this engine has built-in acceleration detectors that unmistakably display on the front panel continuous thrust. Dust particles on the top-plate dance so fast, they clearly float above the engine from the centrifugal force of its whirling “elliptics”.

Power supply PS-3

PS-3 is a custom dual DC power supply for inertial propulsion engine E-8 (RID). Hand-built from scratch by the author in 1992 for E-4, then beefed up in 1996 for E-8, PS-3 delivers upwards 300 watts if needed. However, RID uses only about half that to lose over 27 lbs.

Unlike prior art this drive is lightweight and has no complicated moving parts to quickly wear-out and break, nor requires regular lubrication. It runs on man’s most convenient form of power – electricity so it is clean and quiet. Because RID’s internal forces align with the direction of travel it’s resilient and dependable.

A megavolt solid-state Impulse Drive could cyclically knock-up electrons of an engineered substrate creating upward drag on its nuclei for levitation.

This impulse engine is composed of two carriages that are suspended by springs on the four rods of a mainframe in-line with a control platform. Each carriage holds two counter-spinning eccentric rotors of solid brass weighing 2 lbs each with a 1.5” radius and spin at 300 RPM. This equates to 5 Hz frequency for each carriage which reciprocates, giving a total engine frequency of 10 Hz (cps). The direction of rectified force is upwards within the mainframe.

The Pendulum Test 2008

In May 2009 I installed Revision 6 to allow the engine to gain more ground across the zenith board. See Below. Later this summer I will modify the drive again so that it may carry (not drag) - a load horizontally on frictionless roller bearing wheels and will publish the results on this site.

Electric Satellite Engine

Because satellite orbits decay and sometimes need to be moved about, they require large tanks of retro jet propellant or dangerous nuclear batteries. This means extra weight, space, and limited life. As such, there is an open market for an efficient, electric satellite engine. The required impulse drive doesn’t have to become totally weightless on the ground but it should lose substantial weight while running. RID is a working prototype of such a drive.

The RID’s steady weight-loss equates to about 70% of the engines’ weight and would be like a 185 lb man in orbit suddenly reducing his weight to 55 lbs; he would be shot through space with 130 lbs of thrust. In this case, the engine would propel itself and anything attached to it with 27 plus lbs of thrust.[12] But this is more than enough force to maneuver a two-ton satellite in orbit. Mounted in a 360-degree gimble and guided by a radio-controlled joystick this engine could place an orbiting satellite anywhere – even into deep space and beyond – using solar or nuclear power. Since this drive functions with five separate inertial frames (it has two carriages) it’s exceptionally efficient at 160 watts avg. or just 1/5th hp.

Brass vs. Tungsten Rotors

Both rods are the same height, 3.5”. On the left is a brass rod 1.0” diameter and weighs 375 gr. On the right is a .9375” diameter sample tungsten rod weighing in at 669 grams - almost twice as much as the slightly larger brass rod. Tungsten is usually refined as a powder, then cast and compressed under high temperatures. It machines like cast iron and comes in “one inch” diameter rods as shown above – ideal for Dean Drive rod-rotors because the massive bars take up less space, resist corrosion and keep a high sheen for low aerodynamic friction. Because of the prohibitive cost of tungsten, E-8 has brass rotors.

Mission to Mars

The RID was designed to lose weight only and impel payload already in orbit. However, from the Moon’s surface RID would lift-off and attain orbit with 20 lbs of thrust because the Moon’s gravity is one-sixth g. Though the weight of the engine and its rotors are reduced, the rotor's inertial mass are not and provides the same force as on Earth (a dumbbell in space has the same intractance as it does on Earth but without the weight). From the surface of Mars RID would lift-off with 12 lbs of thrust, Mar’s gravity being about one-third g.

Balance Beam Test

The Balance Beam Test

Though a dramatic demonstration, this test is too demanding on the prototype and stresses gears and linkages to the point of breakage; Even though it is a rigid beam, the engine has to work against the reactive bounce-back of the beam from the weight stack with every impulse.

Mars’ orbit swings it close to Earth once every two earth-years where there is a 6-month window of space travel. With conventional rocket powered spacecraft a manned trip to the red planet would take the full 6 months, then a 12-month wait for the orbits to conjunct again, then another 6-month trip back home to Earth.

Eight RID engines (8 E-8’s) ganged together in free space could safely thrust humans to Mars within a month at a fraction of the cost of dangerous rockets. Once activated, in a short period of time, the spacecraft would impel smoothly to a very high rate of speed. To slow and brake the craft, the 16-cycle engine would simply be turned 180º then reactivated – all mounted safely inside the ship for ease of maintenance and omni-directional control.

Out-Running Gravity

A.   Engine at rest and loosely tethered RID on standby weighs 40 lbs and adaptor table weighs 9 lbs totaling 49 lbs. Note position of brass rod-rotors and spacing between the carriages.
B.   Engine is running with carriages desynchronized (180°out of phase with each other, or normal phasing) producing a steady weight loss of over 27 lbs, the scale resolving at under 22 lbs. Note brass rod-rotor’s position relative to carriages (also with engine off, these rotors would normally drop and not rest horizontally). Unfortunately camera flash overwhelms the LED indicators on the control panel. Photographed with Kodak 200 speed film.

Slingshot to Saucercraft

Shortly after the dawn of man – long before we invented the wheel – we harnessed the centrifugal force of the rotary slingshot. Since then there’ve been no further developments of the potential energy that physics terms “angular momentum”. It has remained locked up in rotary motion. Hold a spinning gyroscope and twist it perpendicular to its plane of rotation and you’ll feel a delayed but powerful reactive force between its two inertial frames. This is the potential that is temporality stored in angular momentum. But in gyroscopes and flywheels this potential is spread evenly about the rotor’s orbit.

Author's proposed hovercraft engine system

Electric Flight: Concept drawing of a trans-orbital electromagnetic hovercraft utilizing radial vectored rotors to produce lift. A Ferro-fluid guidance system about the perimeter tilts the craft in the direction of destination and also by slowing down the rotors in that quadrant. The radar dome on top of the canopy also houses the emergency parachute and a communications link. Solar panels line the top half of the craft to help power the electric saucer.

Eccentric rotors, on the other hand, do not have a smooth, even angular momentum so can be configured into oscillatory motion whereby surge can manifest along the plane of rotation. Then, by shifting this two-frame oscillator complex within its third-frame housing to increase the CAT, angular momentum can become kinetic and the rotor’s centrifugal force is no longer balanced by a centripetal. For a brief moment in an eccentric rotors’ cycle, these two opposing forces are separated and a powerful burst of energy is efficiently released at the expense of electricity. One day soon – like the horse and buggy – tires, roads and bridges will be remnants of the past, thanks to Norman L. Dean's inertial propulsion drive.
