Starship Engines

By: Anthra Andromda

Starship engines come  in  two  flavors;  for  strictly interstellar

propulsion, and for  combined  interstellar/planetary   travel   and

atmospheric use.  This  paper will treat the latter  of  these.  The

engine described here   is   suitable  for  either  interstellar  or

atmospheric travel.

This engine is of a dual-mode design; it will optionally produce

either gravitons or tachyons.


The engine or  propulsion  unit  proper  consists  of  six  discrete

elements (see fig. 1).

1) the shield coil –  required to protect the crew/inhabitants

of the  ship  from any harmful radiation.   The  shield

itself is  a  high-power  electromagnet  operating in a

steady state (DC).

2) the  exciter  coil  is  in   reality  an  auto-transformer,

operating much like a ‘Tesla coil’, but  at much higher

power levels,  voltages,  and frequency. Its purpose is

to excite the atomic  structure  of  the  core material

into production of either tachyons or  gravitons (these

two events   occur   at   different  power  levels  and


3) This element is the ‘pump’,  its  operation is much like a

magnetic shock-tube.   It  will  start   and   maintain

movement of particles from the core in the direction of

the exhaust.

4) The  focusing element. Here the responsibility is to shape

the particle stream into  something useful. This is the

element that can either make the basic  unit  an engine

or a weapon.

5) The  core,  is  a stack of particle producers separated by

some insulating material.  In  a  dual  mode engine the

material for one kind of particle acts  as an insulator

for the other.

6) Not  shown  in  the  figure is the control system, this is

normally a collection  of high speed computers and high

energy power control circuits.

The shield coil surrounding the ‘engine unit’ is  of  a  design that

will allow for  the  development of high magnetic fields. This field

is required especially in interstellar  propulsion;  tachyons can be

very ionizing and therefore destructive.

The magnetic shield can me made by using large gauge wire (low gauge

numbers) and winding many turns.

The gage of  the  wire is important here, as it will  determine  the

amount of electrical current that the magnet can handle.

If it is  at  all  possible,  the  use  of small diameter, insulated

copper tubing may be used. By pumping  coolant  through  the  magnet

larger fields may be generated.

On the outside of the shield magnet a material such as ‘mu-metal’ or

some other magnetic  shielding  should  be  used,  so  as to further

shield the operators from the engine.

This sub-system is probably the most difficult to build. While the

construction of the magnet itself is not difficult, the power supply

may be another matter.

Electromagnets, by their   nature,   develop   a   field   that   is

proportional to the  amount  of  current (amperes)  flowing  through

them. Thus it is important to build a power source that can not only

develop a sufficiently  high  voltage,  but  it must also supply the

required current. This power should be as close to ‘pure’ DC (direct

current) as possible.


The exciter of the system is very much like the ‘Tesla coil’ or

auto-transformer. As an example of an auto-transformer, I submit the

television ‘flyback’ transformer.

While these examples are by comparison crude, they will serve in the

construction of a  model.  As in the  auto-transformer,  the  ‘turns

ratio’ is important.  The higher the ratio the greater  the  voltage

that may be developed.

Another important factor  here  is  the impedance of the sub-system.

Since this will be working at high  frequencies  (several  megahertz

for graviton production,  and 10 to 100 times higher  for  tachyons)

the AC resistance  or  impedance  must  be  taken into account, this

impedance must be kept to a


This part of  the system, like the  shield,  does  its  job  by  the

magnetic field it generates, therefore, the current flow through the

exciter must be  as  high as possible, though not  as  high  as  the


Again the power  supply  is  important, it should be able to provide

the necessary voltage (several hundred  volts)  at  moderately  high

current levels (up to 30 amps).


This element functions much like a ‘magnetic shock  tube’  but again

at high frequencies  (megahertz).   While  the power levels here are

somewhat reduced, it is still important  to  have enough power to do

the job.

The function of the pump is to ‘pull’ quanta of either  gravitons or

tachyons from the  ‘stack’  and  send  them  down  the length of the


This is done by setting up a traveling magnetic wave, see fig. 3 for

a crude schematic of this pump. It  is  again  important to consider

the impedance of this component.

It will be  noticed that the input to this element is pulsed DC, and

that the element is referred to as an AC element.

The nature of this such that it functions in the following manner.

When power is applied the capacitors  charge  in  turn  creating the

effect of many smaller electromagnets stacked end to  end,  when the

last capacitor in the chain is charged, power is removed, thus

allowing the capacitors to discharge

(high voltage/current diodes across each magnet element

will allow for proper discharge of the capacitors).

When the capacitors are discharged power is once again applied.

Because of the nature of the pulsed DC and the current requirements,

high speed switching  electronics  are  called  for  to control this



The focusing element used here would be much like the ‘yoke’ used in

television. The purpose here is to create a beam of particles and to

‘bend’ that beam in the desired direction.

The requirements for the focusing  coils  are  greatly relaxed, but,

the need for high power still exists.


If this system were to be used only as a ‘steady state demo’ the

requirements here would be small.

Simple power supplies  and  switching  circuits would  be  the  only

requirement. However, if  the  system  were to be used in a starship

the requirements would change.

In a flight situation the dynamic  control  of  ‘exhaust’  and power

levels would exist. If used in a planetary mode, one  could probably

‘get away’ with   using   something  like  a  personal  computer  (I

personally would recommend at least a ‘386’ based machine).

However if used in interstellar flight  then  the  use  of something

like a ‘Cray’ would be more in order (though I would doubt that even

the fastest of machines known here on earth would suit).

In an interplanetary mode, where one is not traveling  ‘faster  than

light’, again a PC (486) would probably work.

So that’s basically it. A suitable air/space frame for a ship and

three of these  engines  and  one  could go ‘star-hopping’. Though I

would warn against ‘faster than light’  travel  due to the ‘unknown’

factors involved.

It has been said that when one attempts to travel faster  than light

it must be  done  ‘smartly’,  i.e.  the “jump to light speed”. It is

said that to  merely  accelerate   through   the  light  ‘limit’  is

or on the UFO echo.


NOTE: Some of the sources of information cannot be  divulged, sorry.

But, it  has nothing to do with any earth government. And some

of the original sources I simply  cannot  remember at the time

of this writing.

If anyone is interested in an EGA animation of the operation of this

system, please leave a note on the echo, or netmail me.
