spread the disease
from the top of the cabin
comme vous le voyez en bleu.
as you see in blue.
through these very efficient filters

to go out through the filter.
is a pretty serious problem.
était un sérieux problème.
pour acheter un avion,
to go out and buy a plane,
with computational fluid dynamics,
de la dynamique des fluides,
is create these simulations
in and taking readings in the plane.

is you would start out

into this 3D-modeling software,
dans ce logiciel de modélisation 3D
that I just built into these tiny pieces,
ce modèle que je viens de créer,
the computer can better understand it.

the air goes in and out of the cabin,
d'où l'air sort et entre dans la cabine,
the computer calculates the simulation.

with the conventional cabin is this:
avec la cabine conventionnelle est ceci :

right into people's faces.

vous voyez ces deux passagers

at that from the side,
se propagent le long de la cabine.
spreading across the length of the cabin.
"This is no good."
« Pas bon ».

here is sneezing again,

to effectively push that down
les germes vers le bas.
push those pathogens down.
at the same scenario
passenger sneezes,

to infect any other people.
à coté de cet homme
sitting next to the middle guy
no pathogens at all.
seulement pour le passager central
if the middle passenger sneezes,
du siège à la fenêtre
passenger sneezes
this mean for the world?
pour le monde ?
pour aller vers la vraie vie,
into real life,
that I built over here,
avec ce modèle 3D que j'ai fait
airflow patterns coming down,
actually cost the world
a coûté au monde
could actually cost the world
to take an airplane out of service
et des mililers d'heures
