GEOMAGNETIC LEVITATOR DEMONSTRATION VALIDATION PROCEDURE
The Free Flying Magnetic Levitator, U. S. Patent
4,874,346, can be validated as a useful aerospace propulsion system
in the earth's magnetic field, first if it is built
with superconductors using cryogenics and second if it is built
with
ferromagnetic materials at room temperature. There
are 3 demonstrations to establish the basic propulsion principles.
The first demonstration is that of a typical
solenoidal electromagnet hanging from a power tether. It exhibits no
translational
force and no coupling efficiency. The second
demonstration is that of a straight length of electrical conductor at right
angle
to the earth's magnetic field, also hanging from a
power tether. It translates but since the forces on all sides of the
supply
lines, the tethers and the conductor line balance
each other there is no net translational force and no coupling
efficiency.
The third demonstration is that of a toroidal
winding of the same weight and thickness as the length of conducting line
in
demonstration number two with it's thickness at
right angle to the earth's magnetic field, also hanging from a power tether. It
translates significantly more than demonstration
number two showing that it has near to full coupling efficiency and real net
translational force.
showing that NASA's Superconducting Wind
Tunnel Magnet could deliver a thrust to weight of 2.5 and specific
impulse
of 360,000 seconds in a 0.5 gauss radial magnetic
field and if it was a toroidal winding the same performance in the
earth's magnetic field.
Once validation of the basic propulsion
principles are established demonstration of launch vehicle quality of
performance
will be available using ferromagnetic materials at
room temperature.
SPACEPLANE APPLICATION FEATURES
Using an oxygen liquifier, aviation fuel, an engine
driven dynamo to charge the batteries of a Geomagnetic Levitator
propulsion system, a Commercial Spaceplane could
operate silently out of any airport with a 5000 ft runway with no
exhaust plume, fly out at subsonic velocity and go
to orbit. Old 727's could be cheaply retrofitted for space travel
with no heat shield tiles and no reentry problems
because high specific impulse allows for retro propulsion to
deorbit
and land.
Right now, all the equipment is in hand to test
a very small reusable levitator launch vehicle. We are currently
.
exploiting this technology.
