That's got to be some of the best CGI I have ever seen!
Jes' fer grins, I did some rough numbers as to how much "pull" on a jet engine the partial vacuum it's creating in front of it might be if the plane were standing still but spooled up.
Assuming a 6 foot diameter intake and a 1 psi pressure drop in front of it and neglecting everything else, there would be a pull of about 4000 lbs just due to the vacuum (partial pressure, technically) created by the compressor.
Assume a 6' diameter disc with 14.7 psi on one side and 13.7 psi on the other side.
6' = 72" diameter
(72/2)
2 X pi = 4072 square inches of engine inlet opening.
Times 1 psi of "suction" (pressure differential) = 4072 lbs of "pull."
A pressure drop of only 1 psi seems kind of light, but it's scalable, that is, a 2 psi drop would yield an 8000 lb pull
on the engine.
And neglecting everything else.
Jes' noodling it around.
Some folks do pushups before their coffee in the morning. :D
