How do I make monocopters

The future of our forum and a little treat

Quote from S.nase:

I think that such a high structure without Vekror control will be too sluggish. Simply arranging four pipes in a square and with a quadrocopter (speed control) on the ground will not work very well, it would certainly commute extremely.

I wouldn't even doubt that, classically falls under MUP.

Quote from S.nase:

In addition, so many surfaces (even exactly aligned in the direction of the air flow) slow down the air flows extremely because turbulences are created on the long surfaces of the tubes. With a single large tube, the ratio between wall area and air flow cross-section is significantly better than with four thinner tubes of the same length.

I already assume smooth-walled pipe.
In the end, the whole thing is defined by the air speed in m / s,
Hydraulic diameter in cm, referring to this, pipe friction resistance R in Pa / m,
Consideration of individual Zeta coefficients with the result Delta P in Pa
and so on......................

I've been doing this for almost 40 years now, at the beginning I had to learn arithmetic,
Then the slide came as an aid, today I also take a look at my thumb.
