Latest developments on Subitam class thrusters

The new Sub321n4. Heatsinks have been installed both on the thruster (the black box above) and the cart (below). The whole prototype weighs about 512 grams

Dear readers,

while ASPS is looking forward the commercialization of F432 class thrusters in the form of prototypes, Laureti is also improving the Subitam class.

The latest variant is the Sub321n4 which is estimated it could, in its current state and given an adequate control system and a power source, reach Mars in 12 days .

With the addition of solar panels (not installed yet) and additional lithium batteries this prototype would be able to reach Mars and recharge its batteries in Martian orbit and then to mound slowly
to take samples of the soil and return to Earth’s orbit.

As we will illustrate in Nova Astronautica n.171 Vol.42 2022, in order to reach Mars many improvements will have to be applied and 4 prototypes of type Sub321n4 each with 2 degrees of freedom mounted on 4
maneuverable semi-axles must be used [because one thruster alone is not enough for controlling the flight attitude: like any spacecraft auxiliary thrusters are needed for moving on and around X,Y,Z axis].

Solar panels will have to be adapted for this purpose because they will be the only source for recharging lithium batteries. Of course, driving, telemetry, remote control and driving systems will have to be included.
The possibility for the PNN to obtain enormous speeds is linked to the fact that the law of
motion of the PNN is different. PNN does not obey to Newton’s law of motion! Newton’s law of
motion with PNN transforms into this increasing curve:

In essential terms, the PNN thrust gradually increases over time with the same power output and is
another -physical- world compared to the second law of Newtonian dynamics!
So the time required to reach Mars is enormously shortened and everything happens, unlike missiles,
without losing a gram of mass but only electric power!

ASPS estimates the arrival times from Earth’s orbit to Martian orbit in about 12 days.
In order to reach this goal an essential fact that must occur is that the state of violation of action-reaction principle lasts over time, i.e. it is necessary to maintain the thermal dissipation of heat (F432 is not equipped with heatsinks) so that the prototype is not damaged during the non-Newtonian thrust.
The increase in thrust of the PNN involves the change over time of various parameters unknown to
Newtonian mechanics.

In addition to the essential “duration” (due to the cooling system), the new prototype also includes control of the impedance variation in the thrust phase and control on the phase drift caused by the continuous variation of inertia.
