Turbofan airflow patterns.

737 fan section. The bl ades slide individually into the hub and reside wi th a bit of a gap. As the de-ice and other seasonal crap fluids seep/fling out of a spinning hub, it dries quickly on the blade while at power. We see the pattern curve as it slides out , where not only it’s at higher velocity, but the fan also starts to load up and carve the air for thrust. T he fluid changes direction from the air flow instead of just sliding out centrifugally. Patterns in physics are cool.

Bigly fans scare me for some reason....

The new GE9X engines for the 777X are larger diameter than a 737 fuselage:

They are big, here’s one mounted on a 747 for testing:

Don’t worry though, even small intake fans are dangerous:

Does long term exposure to de-icing fluids eventually damage the blades?

Not so mucj. I ts not sprayed in there as it runs. It’s sort of picked up from the environment like paint overspray and such. Like your car just gets dirty from being around.

This is good Oppo.

I remember reading a book in elementary school about how jet engines were made. I always thought it was neat how the splines on the base of each blade hook together.

Wait till I discuss SFC calculations and the ridiculous consumption of Russian afterburners.
