I don't see a need to accept any unusual conclusions such as claims of
antigravity to see the value of electrohydrodynamics to flight.
Remember that if this has been top secret for 40 years, then there
might be flakey props mixed in with real props. 

How does an electric wind device work? First there is a pointed or
edged shape to concentrate the electric field gradient. Then there is
a high DC electric field potential, say 7000 volts. The gradient must
be under any conditions less than the breakdown gradient of
approximately 3MV/meter, otherwise the sparks will cause intermission
of the effect. Then if conditions are right you get a steady plasma
cloud generated around the edge or point where the gradient is
highest. It is faintly glowing purple or bluish. 

If the point is charged negatively you get a negative plasma
cloud because the positive ions are stripped away in the high gradient
field. The negative cloud blows away from the point and follows a path
that leads to ground. The current is on the order of 100 micro amps
and the power is about 4 watts in experiments I have done. You can buy
a -7000 VDC power supply from the local Minolta or Xerox repair
or sales office. I paid $40. They also have very fine 2 mil tungsten wire
that is very for studying this effect. The repairman gave me 6 feet
for nothing. 

What is an electrogas device? It is a generator that makes higher
voltages from smaller voltages and uses any compressed air source for
power. Here is a possible design, though if you understand the basic
principles, conception of many variations is possible. 

Take a metal tube about 0.75 inch in diameter and at least 2 feet
long. Find a way to stretch a fine wire down the central axis of the
tube, using only electrical insulators for support. Connect the
-7000VDC source to the wire and the tube to ground. Blow air
continuously down the tube. One way to do this is to hold it out the
wind of you car while it is moving. Connect the gorund to the frame of
the car. 

What you can expect to happen is that the wire+tube device will
generate a continous source of positively charged air that will not
initially be able to overcome transverse convective air velocities in
time  to be able to make a connecting path back to the frame of the
car, that is ground. Because the capacitance of the car/earth is very
low, on the order of femtoFarads (not a good capacitor) only a few
micro coulombs is necessary to attain the 3MV/meter gradient necessary
for spark discharge. This effect resembles a Van de Graff generator.
It is powered partly by the engine of the car which pumps the charge
away from the car, and partly by the -7000 VDC power supply which
pumps the charge accross the gap in the wire+tube configuration. 

Now imagine that this is not a car but instead a jet aircraft which
can easily be several kilometers away from the earth. Also imagine
that the single small tube with a powersupply of 4 watts is replaced by a
more ambitious system several thousand times more powerful supply and
which is boosted by the jet engine exhaust. The current leaving in the
jet exhaust could be on the order of 0.1 amps (100,000 microamps). But
this system cannot increase in charge forever because its capacitance
is low wrt the earth.

What happens next is that any exterior sharply curved edges will have
a high electric field gradient. The leading edges would then be
exposed to oncoming neutrally charged air. The high gradient would
create a plasma around the leading edge. There would be an oppositely
charged cloud trailing in the jet exhaust, and the path of the leading
edge charged particles would take them in the direction of the tail.

Meanwhile the potential gradient around the top and bottom surfaces of the
wing would repel the plasma fluid in a direction perpendicular to the
usual streamlines. This has little effect on the lift or drag as
currently conceived. 

The leading edge effect is much stronger and creates a pressure wave
that extends forward from the leading edge further than the leading
sonic pressure wave. Thus the sonic boom could be reduced. 

Also additional electrogas devices could be built into the leading
edge surfaces just aft of the front edge but just before the wing
tapers. These electric winds would assist the air in overcoming the
adverse pressure gradient that often results in seperation. Thus drag
could be reduced. These added EG devices would work in concert with
the more powerful ones such that if these ions could not complete a
path back to the surface of the wing, the charge of the entire body
would be increased. If this works, then it would be possible to
construct lifting bodies with unusual non-aerodynamic shapes, vis the
stealth fighters. 

The plasma sheath that surrounds the plane would form a radar
reflective surface due to it's lack of features. 

Also any such aircraft would need moving air, and would have to attain
some altitude before the effects would work well. Thus conventional
lift would be necessary for take off and landing.
