During an online discussion with an employee of an Italian aerospace company specialized in the electric propulsion field, Laureti revealed that ASPS has realized a prototype called Fert242 that will run, or better, that will thrust, against EmDrive in the race for the Holy Grail of propulsion.
From the discussion emerges ASPS’s will to make its public debut on the propellantless propulsion scene. In fact Laureti announced that the prototype has been delivered, in mid-November, to the department who will prepare the device for public tests which, it seems, might be held in a matter of months.
Let’s have a look at F242 performances:
- Thrust: 600uN (with a tolerance of +- 100uN)
- Input power 150W (the prototype is depowered for safety reasons)
If we compare them with those of EmDrive:
- Thrust: 20uN
- Input power: 700W
We deduce at a rough guess that F242:
- is about 30 times more efficient
- consumes less: 150W against 700W
Also, ASPS’s thruster is 10 times lighter than EmDrive.
Laureti specified that of the 150W of input power, only 5W are actually converted in thrust. The rest in fact is dissipated in SWR, the PNN nemesis (here you can read more about the problem).
Despite this issue, and although the fact that F242 is a depowered version of previous ASPS prototypes, this little thruster still has all the numbers to beat EmDrive!
I wonder what an ASPS engine could become once that SWR problem will be solved..
But there is more..
The company appears to be more than a simple interlocutor in this rumor: in fact Laureti suggested them to evaluate, after a market analysis, if they may be able to sell a commercial version of F242 by 2017!
Last but not least, the company has its own vacuum chambers for testing ion thrusters, so they could (independently) test ASPS’s engine as well!
Edit 11/30/15: the interlocutor commented on this blog clarifying the position of his company. You can read it in the comment section.
Then, Laureti restated that he’s not worried by NASA and EmDrive competition, because they know nothing about the physics that regulates propellantless propulsion as they’re still messing around with abstruse theories like “quantum virtual plasma”.
Thus stay tuned, things are getting interesting!
