Bypass ratio is the biggest trade off with engines. This is going to be huge.

Game changer. If I were the .mil, I would be asking for retrofits to existing jets.

Second Video does not work.

So variable bypass ratio for fuel savings, plus an extra airstream for active cooling of avionics and such instead of dumping it into the fuel, requiring fuel to be temperature managed BEFORE IT EVEN GETS INTO THE AIRCRAFT! (Looking at You F-35) Looks good to me.

In the first video, I strongly suspect that this is not the actual variable bypass geometry, since it involves two nearly right angle turns for the supplemental air.

One way we were told to do this is by painting our trucks white in the summer. Works well enough at a stateside base, however when you get into locales where you don't want to stand out and it's hot as fuck...

I knew about this, but the necessity for the aircraft smacks of bad design imho.
