An update about PNN: prototypes F449 and F432
« on: 09/16/2017 06:52 AM »
First things first, ASPS has found external collaborators who are helping the association to adapt one of its prototypes, F432, for space flight. If all goes well, within the end of the year the PNN spaceship will be ready for spaceflight.  :)

The first attempt has been made with F242 ( already discussed here): modifications have been made to make the thruster autonomous in its dynamic through the removal of the external power cables. This means power supply through a battery pack and amplifier plus preamplifier installed directly onboard the prototype. Also, the ignition command is sent via remote control.  This project has been jokingly nicknamed telefonone , ďbig phoneĒ in Italian.

This type of configuration is testable under any verification procedure that will be decided by eventual financiers, thus tests on ballistic pendulum, torsional pendulum, frictionless test tracks etc..

The purpose of this prototype was to reduce through constructive approaches the temperatures developed by the propulsion unit.
The overheating is due to the ferrite cores that are used to increase the magnetic fields, as theyíre created using the limited amperes available from ASPS power supplies. As the ferrite cores work at millions of oscillations per second, the ferrite reaches temperatures that are critical for the whole system: the thermal camera detected a temperature above 250įC (full-scale). This intense heat propagates to all thruster components, hence compromising its integrity. Unfortunately it isnít possible to realize a metallic frame because the induction currents would be uncontrollable under rapidly changing magnetic fields. Thermal deformations are able to compromise the measurements of the thrust as a result of deformation of the coaxial cable.

A possible solution could be the use of ceramic materials but ASPS resources arenít enough to make customized components for PNN thruster. Therefore utilized ferrites and ceramics are common components found on the market and then wrought as much as possible to fit the prototype. For such motivations F449 power frequency has been increased from 144 Mhz of F242 to about 432 Mhz to reduce the prototype dimensions and consequently the overheating damages (although the temperatures remain the same). Last experiments have been conducted ad 449 Mhz, where it has been detected a thrust in the opposite direction.

There is a plausible explanation for the phenomenon, Laureti says: phase shifters are made of ferrite and it would be improvident to think that they can maintain the fields phase as it happens without them. The fields through ferrites can operate in maximum phase, thrust in a direction with a phase of 0,360,720 degrees, or with 180,540 degrees that is thrust in opposite direction (quadrature 90,450 degrees) and no thrust when the fields reciprocally auto-erase themselves.

However incontrovertible PNN thrust tests can be made in ďclosed boxĒ (prototype core canít be disclosed) through battery power, thus without coaxial cables for external power that deform when heated.

At the moment, incontrovertible PNN tests with external power cable can be made only in ďopen boxĒ, where one can directly observe the force created by thrust elements.
This is a situation that ASPS canít afford because itís looking for resources to industrially develop PNN.

However all tests for both F242 and F449 are feasible in closed box with battery power supply after it has been conveniently prepared and with commands transmitted from remote .

The current electrodynamic violation procedure of action and reaction principle is a more effective variant than the one related to a patent filed on April 22nd 1998 that can be found at EPO (European Patent Office) with the following registry data:

ITRM980250 (A1) ― 1999-10-22 Ė Sistema di propulsione elettromagnetico

Today PNN buries its roots in this patent.

Basically the patent covers what Maxwell couldnít know, not because he wasnít capable but because he hasnít got the technology to investigate further.

I report Lauretiís words about this issue:

Quote
The first who thought to interactions between open circuits like the dipoles, for what I could find from a historical point of view, was Maxwell.

He explicitly says at page 163 Vol.2 of his Treatise:

Öno experiments on the mutual action of unclosed circuits have been madeÖ

and I have to say that at that time it was almost impossible to do such experiments. Iíve discussed more extensively this topic in Nova Astronautica n.84 Vol.20 2000 pages 3-9 as well as in n.77 Vol.18 pages 1-17, where it is described the standard procedure for the violation of Newtonian action-reaction principle through standard electrodynamics that led to the above mentioned patent.

After F449 the Association has created what seems to be the lucky thruster whoíll make it into space!

The prototype name is F432 and it has the following specs:

Input power: 250W
Thrust: 250 mg ( measured at less than 1 minute into testing, because Laureti had to turn the power off to avoid overheating)
Once again it has been observed the thrust superimposition phenomenon (Iím calling it this way to convey the idea but it might not be technically correct) that first manifested with F242: in short words under a constant power input the thrust slowly builds up over time and once the power is turned off the prototype keeps thrusting, like if it had to work off the previously ďaccumulatedĒ thrust.
This behavior previously led Laureti to hypothesize that PNN moves with uniform accelerated motion rather than with uniform linear motion.

What does F432 lack to become a small starship? I quote Lauretiís writing on ASPS webpage (original in Italian):

Quote
It lacks a battery power supply (and solar panels for recharging), amplifiers and preamplifiers, telemetry etc. In detail, amplifiers and preamplifiers must be far lighter than the mastodons actually in our possess. Certainly the best thing would be to couple rechargeable batteries with an RTG, but we canít afford it because our country has repudiated with a referendum [against nuclear power Ė E.N.] the work of Enrico Fermi, the first who managed to create the first nuclear reactor. Repudiated on the basis of extremist environmentalist propaganda, with the vows of who canít usually distinguish physics from physical education.

Since apparently RTG technology is forbidden in Italy (I say apparently because I hope Italian State will find a loophole, when itíll be the moment), Lauretiís choice has to fall back on lithium batteries but itís not a simple quest because the required specifications arenít common in the products on the market. I post a Lauretiís discussion about this topic (original in Italian):


>Well, this battery pack isnít nuclear but rechargeable lithium:
>https://www.niu.com/it/m1/specs/
>They allow to power a small electric motor for city mobility up to 60Km
>48 V, 32 Ah, weight is about 8 kg

Laureti: They donít adapt to any of the values of our amplifiers.. we bent over backwards (or better: my collaborators did) to find the right ones.. and the most powerful ones canít be even freighted by plane from America!

>Ok, Mars is farther, but such batteries are rechargeable, so with some help from solar panels.. who knows?

Laureti: We need the pair rechargeable lithium batteries and RTG batteries (plutonium, unfortunately) to be able to land on Mars with some sensitivity, collect martian soil and then head back to Earth (no crew of course!). With lithium batteries alone we can only have a stroll around Mars and then go back home.

>However, if I can ask a question.. What means do you think to use to send your equipment into space?

Laureti: Iíve got two answers that I canít give.


In the above mentioned writing on ASPS webpage he also published a couple of raw sketches of the future PNN test spacecraft configuration.

Hereís the side view:


and the front view:


Laureti wrote that after many hardships, maybe (emphasis on maybe) within the end of the year ASPS will honor its old dream of a PNN spaceship for Mars! In fact, unlike F449, prototype F432 is actually in the process of being adapted to space flight, thanks also to the help of four formidable Italian collaborators.

Quote
Unfortunately we can carry only moss and/or bacteria instead of elephants. This is what our personal budget allows and itís the consequence of my  ASPS-Calmagorod stubbornness , because for decades Iíve never bent the knee in front of various Baal (that is NASA,ESA and friends) who only wanted the know-how of PNN in exchange for ďfried airĒ (an Italian way to say "nothing"

If youíre asking yourselves why the cross-shaped fore of the future F432 spaceship, itís because Laureti dedicates it to all those detractors who yelled for years hate and derision against ASPS work and Lauretiís faith in God.

Here's some images of F432:

I would like to emphasize an essential point in the inertia of pnn
The violation of the newtonian third principle necessarily involves rewriting the principle of inertia, which displacement  is no longer a uniform straight motion but a uniformly accelerated motion unless a dissipative process (similar to thermal irradiation) is in progress during the implementation in velocity of such inertia law.
Conclusions: A real Mars journey may be shorter in times when few electric energy  compensate the dissipative process. More energy principle conservation need that mass decrease as pnn velocity increase.

I believe I know exactly what this is.  It looks like what I like to call a near field reverse magnetic phased array but I can't tell from the information given exactly.  I read here https://forum.nasaspaceflight.com/index.php?topic=43756.0 that is uses frequencies in the MHz which is near the frequency I believe the device needs to run at but also needs a dielectric to shorten the wavelength so that 1/4 lambda is on the order of cm to operate in the near field region.  In one image I have seen of this it does suggest a separation of 1/4 lambda.  It also uses control of phase quoted below:

phase shifters are made of ferrite and it would be improvident to think that they can maintain the fields phase as it happens without them. The fields through ferrites can operate in maximum phase, thrust in a direction with a phase of 0,360,720 degrees, or with 180,540 degrees that is thrust in opposite direction (quadrature 90,450 degrees)

As the ferrite cores work at millions of oscillations per second, the ferrite reaches temperatures that are critical for the whole system

I can't tell what your using for a dielectric but it looks like in this image you are using a dielectric which appear to be between the coils.  I am guessing the coils are wrapped around the ferrite disks?  Is the dielectric a ferrite also?  I suspect from one statement the ferrite is a phase shifter? 


If a near field reverse magnetic phased array does work I have stated because there is not enough momentum in emitted light that I would suspect instead an induced flow in the vacuum possibly.  Your statements about your ballistic pendulum deflection test here:
in short words under a constant power input the thrust slowly builds up over time and once the power is turned off the prototype keeps thrusting, like if it had to work off the previously ďaccumulatedĒ thrust.

Suggest to me an induced flow in the vacuum that seems to carry momentum.  They suggest eliminating relativity from the equation and I am not sure how they arrive at that but I do think if you can induce the vacuum to carry you then you may be able to counter relativistic effects. 

I'll attach the patent and the thread I started on an idea I though was origional.  Later I found a patent from 2014.   http://forum.nasaspaceflight.com/index.php?topic=36911.0

I have been looking for some test of this reversed magnetic near field phased array so that I would know for sure if it works.  If you have any evidence this is what I think it is and if it works I would be very interested.  Thanks

-Dustin.

P.S. The 2014 patent advises not using the ferrite for some reason, I don't qutie remember though. I did suggest possibly using ferrite cores in the center of a coil configuration here: https://forum.nasaspaceflight.com/index.php?topic=42978.msg1718338#msg1718338
The patent suggests using barium titanate or some other dielectric that drastically shortens the wavelength at MHz.

Hope it helps.

Have you done any tests/videos with rotary rigs? Balance based tests do not rule out many possible thrust measurement errors...

I agree I would highly suspect thermal effects and would seek ways to eliminate them from the measurement process.  Isolate variables.  The pendulum experiencing a lasting thrust is also a possible thermal effect but then again, until you isolate the desired variables it may remain a mystery.
