as promised here’s the second part of ASPS activity update.
The great news is that after F449 the Association has created what seems to be the lucky thruster who’ll 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 (I’m 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 “accumulated” 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 Laureti’s writing on ASPS webpage (original in Italian):
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 can’t afford it because our country has repudiated with a referendum [against nuclear power – 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 can’t 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 it’ll be the moment), Laureti’s choice has to fall back on lithium batteries but it’s not a simple quest because the required specifications aren’t common in the products on the market. I post a Laureti’s discussion about this topic (original in Italian):
>Well, this battery pack isn’t nuclear but rechargeable lithium:
>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 don’t 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 can’t 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: I’ve got two answers that I can’t give.
In the above mentioned writing on ASPS webpage he also published a couple of raw sketches of the future PNN test spacecraft configuration.
Here’s 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.
Unfortunately we can carry only moss and/or bacteria instead of elephants. This is what our personal budget allows and it’s the consequence of my ASPS-Calmagorod stubbornness , because for decades I’ve 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 “fried air” [an Italian way to say “nothing” – E.N.].
If you’re asking yourselves why the cross-shaped fore of the future F432 spaceship, it’s because Laureti dedicates it to all those detractors who yelled for years hate and derision against ASPS work and Laureti’s faith in God.
Here we are then: if all goes well soon we will finally see an electromagnetic thruster at work in space and if the uniform accelerated motion hypothesis is right we’re in for a wild ride!
