Who knew it would be so complex?

One curiosity of this aircraft (afaik, it is the only commercial airliner) is that the main landing gear has no cover:
It is interesting that they didn't even try a partial cover.

EDIT:
From the same author, claims chevrons are about more controlled vortexes and doesn't even mention sound/frequency node dispersion. More specifically "turbulence amplitude" I suppose it's close enough though.

Keeping MAX quiet - Chevrons


I watched a few other of his videos, good but not going to be 100 percent complete given the limited lengths.

The chevron jet intensifies both the R2222 and R3333 cross– correlations within 2 jet diameters of the jet exit. The amplitude, length and time scales of the cross–correlations of a LES velocity field are investigated as functions of position and are found to be proportional to the turbulence amplitude, length and time scales that are determined from a Reynolds Averaged Navier–Stokes (RANS) calculation.
Back to wheels:
The 737 air-frame goes back to 1968, I really doubt that a clean sheet design would ever go back to a similar solution.
