delta-T based pulse unit idea
« on: April 03, 2005, 08:25:31 PM »
( delta-T is an octahedral antenna with coils )

This is something thought of in terms of how a 'UFO' propulsion unit would work.

There's the lift, and also the directional control.

Not tested, so I don't have exact ratios/formula worked out for spacing the coils, or the weight-mass : voltage, or the pulse rates, or the exact means of applying the 'load' for the directional control -

I'm not sure as to how interwoven coils affect each other in-practice, so I'm finding that part harder to ''visualise'', because the pulse required for the lift will of course need to be on-going for as long as whatever is to remain in the air, but to move it along at whatever height it is off the ground at requires an application of the 'load' in the desired direction of travel.

This can be a continuous wound coil(s) unit around the whole perimeter of a typical disk-shaped craft, in this case the pulses will be 'sweep' like. Can also be four at right angles to one another, or 6 at 60 degree intervals, and so forth. These will affect how the craft (or whatever is being moved) changes direction - if you have a 4 coil(s) then it'll only be able to do right angles for example.

Using a typical delta-T style with the 4 coil(s), think of it a three separate instructions to the coils -

there is a background continuous ON voltage - same around the whole craft

one pulse moves clockwise at a specific rate

the other pulse moves counter-clockwise at a rate determined by the rate of the clockwise pulse


eg, for every whole clockwise pulse (1st thru to 4th coil) there will be 0.67 of a counter-clockwise pulse

 

This is for the lift ;  I've heard these things can easily go thru the roof, and probably the other direction downwards too, and certainly I wouldn't recommend starting on a large scale as it will likely just blow-up in various ways during testing the pulse ratios, so it'd be wise to test small units in small incremental changes of pulse rates - use smaller voltages, find the best ratios, get a small model going first, as the ratios and formula are going to be the same for any larger sizes.


Again, not sure about how the coils will affect one another, they'd need to be interwoven (braided) but of course if they are encased/insulated then the field aint going to do much, so there is going to need to be taken into account any cross-overs from one coil to the other windings beside it.

Probably works better with separate coils for directional control. Possibly moves at same kind of high velocities, so don't aim towards anything breakable.

See this as being operable with two stick controls - the pulse is altered for the lowering and raising of the craft with one of the sticks (or landing-gear style control (bi-directional), the other applies the 'load' in the direction of movement kinda like an arcade controller or trackball.

The savings on making 1/8th scale or so is great but,the power required is on a different
geometrical scale. I doubled the size on an item and found out I needed 6 times the power
and also found out Thomas Brown figured out for us liniar stacking isn't the best way.
That's why he drew his device with multiple side by side elements.But with coils it's different
maybe, could you tell us what happens if you stack 2 sets?

What is a geometrical scale of power?

A ratio a constant in this case between size and power , double the size 6x the power,
quaddruple the size 6 x 6 the power. Not a unattainable amount by calculation about
1.3 kilowatts for a forty foot craft. It's figuring out how to reliably generate the
required voltage in a light package without componet failure that has me stumped
right now. The need for more time at the bench is present. Of course that calc
only includes lift, side thrust and landing lights. No comforts from home.
