What PNN needs for the take off

The long arms ballistic pendulum located at Calmagorod lab. A view from above.

Dear readers,

first of all an update about ASPS Calmagorod laboratory status after the earthquake: the structure has been declared unusable. The building fortunately sustained some minor damage and it does not require big reparations. However, ASPS has to wait authorities green light in order to enter the lab and until that moment the special ballistic pendulum used to test F242 is inaccessible.

I would like to propose, here and in the forthcoming posts, a selection of Laureti’s replies posted in various discussions about PNN and EmDrive laying around internet, as they contain some interesting cause for reflection:

the first one is from a discussion on an Italian site, where some users provocatively asked Laureti the reason why PNN hasn’t took off toward Mars yet.

If you want the take off – writes Laureti – you need 1 million Amperes rms in UHF and you have to enter in this order of ideas:

  1. Remove electric power transmission cables
  2. Why? Because I would like to see how you set up a transmission line with a 10^-8 Ohm impedance.. or worse, how you adapt a line from 50 Ohm to 10^-8 Ohm if you want 1 million Amperes in UHF.
  3. Therefore, there is the need to build the prototype inside the power amplifier (or vice versa)
  4. Even worse, I presume that you have to build the PNN thruster inside the power transistor (or vice versa)
  5. Thus you have to create a new kind of transistor(s) because the best materials today available are highly unsuitable for a take off capable PNN.
    In short words: you must stabilize a short circuit in UHF!
  6. You are afraid and you want to use 1000 Amperes instead 1 million? Then you have to integrate the whole system with ferrites and dielectrics, that today don’t exist, inside the amplifier + prototype block.
    So one should create a new Apollo project with thousands of engineers and to make them work like slaves together with the thousands and thousands of technicians required for all the components.. I presume that through the fusion between all the space agencies maybe it would be possible 🙂
  7. Mocked because no one is still interested to PNN? Don’t worry, I’ll do on my own the journey to Mars within 2017 🙂

I tell you this: for the moment I barely reach 10 Amperes so the thrusts are still low and now, due to earthquake, I haven’t got anymore a long ballistic pendulum to best highlight the prototype thrusts.

Stay tuned for next post!

  1. sempre che uno non voglia sperimentare altro rispetto al decollo verticale, se il decollo fosse in orizzontale basterebbe un decimo della potenza dove c’e’ atmosfera, come?
    sfruttando la forma alare della nave spaziale,
    certo si dovrebbe comunque ricorrere al decollo verticale nel caso di atmosfera rarefatta, ma con gravita’ ridotta serve meno potenza 🙂

    1. Ciao Valerio,

      bella idea il decollo orizzontale. Si potrebbe risparmiare energia anche sula Terra, almeno nei primi modelli di astronavi pnn. Una sagoma ad ala volante aiuterebbe in tal senso, anche se per le atmosfere più rarefatte occorrerebbe un’apertura alare più generosa per generare portanza.


      1. Si l’atmosfera e’ rarefatta su marte o altri corpi celesti piu’ piccoli della terra ma la minore gravita’ compensa anche.


      2. E vero bisogna tenere conto anche della gravità più bassa. Se non ricordo male la NASA aveva allo studio un robot elicottero per esplorare Marte e stava studiando delle pale molto lunghe per adattarsi all’atmosfera più sottile.
        Per il decollo verticale mi ricordo che Laureti aveva ipotizzato dei condensatori da scaricare in fase di decollo per fornire ai propulsori pnn un aiuto extra


  2. Con il decollo orizzontale sfruttando la forma alare della nave spaziale serve un decimo della potenza. Quindi a) decollo orizzontale in presenza di atmosfera e b) decollo verticale in assenza di atmosfera

    Terra velocita di fuga 11186 m/s
    Marte velocita di fuga 5027 m/s


Welcome visitor, please share your thoughts. English is better but Italian is accepted. If you want to learn more about ASPS please have a look at the blog menu
