Flytox II hypothesis (details)
Flytox wrote:AMHA, the reactors push backwards, so the zinc is pushed forward in the same way (reaction). Support is done on the air "horizontally" and not on the track in one way or another. So the zinc moves forward, so there is air flow on the wings, which will create the necessary lift when the speed is sufficient, the zinc takes off as usual.
I doubt it because “the balance of this system” would hold by the fact that
if as it appears in the definition of the problem, the treadmill exactly compensates for the rotational speed of the wheels, the zinc cannot be pushed forward, it remains stationary since the conveyor belt would not move forward. There would therefore be NO possible support on the air. The anecdotal airflow in a storm at an airport is not enough to lift a 747. So the necessary 'lift' would range from “
does not seem to be carried out except slight in the event of a storm"To rather"
close to zero ”. The zinc would still not advance. And so the “
when the necessary lift is reached" it would be "
never" or "
all of a sudden”But uncontrollably and very violently, see point“ 3 ”below:
(Because at some point there would inevitably be a tipping point on the weakest link in the balanced system ... correct me if I'm wrong, but without being too wrong what I said is absolutely correct)
1) I explained the suction phenomenon which is correct, on the ground, the air in the front would be pushed backwards and would create a relative vacuum in the front, quickly filled as a fluid (but the phenomenon is visible on the ground), because it is then that in the video below, we see this curious phenomenon of the air which seems to come from behind to go forward, which seems to defy the effect that the 'we imagine a reactor in operation (but only in appearance). We can see it perfectly in this sequence of an airplane with the wheels locked: (it only lasts 5 seconds, and the effect cannot come from the wheels, because those of an airplane are not driving). So the question of the possible lift at a time “T” would in any case be null or hampered / disturbed by the co-lateral turbulence produced by the immobility of the airplane and this “vacuum cleaner which would work ã donf ... reactors in acceleration at maximum take-off thrust ”)
2) Assuming that the treadmill is foolproof, the weak link in the balanced system is ... the ... wheels. Those of a Jumbo Jet 747 have a tolerance given at 260 MPH / 418 km / h
370km / h being the minimum take-off speed and 420km / h the maximum (Beyond that, we are in the “tolerance” ranges, but things still go wrong without going that far. So we would fall back on what Guy said, and what I said in this answer:

(Explosion of several tires, rewind at 3:14) So without wanting to be categorical, and as I described it, it is from this moment there, on the ground, that everything would go into a spin ...
3) Newton's law:

... and there, beginning of the problem caused by the explosion / fire of the tires which would break the point of equilibrium. What could happen other than a sudden, unpredictable acceleration one way or the other? - there the engines are at the maximum thrust planned for take-off, and the plane would suddenly be released from its grip - there would then suddenly be a violent rotation on itself and / or a reversal of the plane then ? The thrust force exerted in one direction by the reactors, would provoke an uncontrollable reaction in the opposite direction, towards the direction of the breaking point of the equilibrium ”
the force to be dissipated must be equal in the opposite direction”According to Newton. Pieces of tires could even be sucked up and swallowed by the reactors. The plane could then burn, leave the carpet in an unpredictable direction, the crazy zinc would probably get damaged in a rollover, and be uncontrollable anyway. The pilot would not have time to play on the flaps, the rudder, the speed or anything, the plane obviously not being designed for this kind of guidance / control.
