"Without a propeller"!? When have you ever been able to see a propeller on a flying aircraft??

[–] Crackhappy@lemmy.world 9 points 1 year ago

True, it's a blur, just like last night with your mom.

All the time, the tip has to stay subsonic so they don’t spin that fast. 1021 RPM on an H-model herc for example.

the tip has to stay subsonic - that's what she said

Huh, interesting. It just seems like from a distance, while both it and the aircraft are moving fast, a visual determination of whether a propeller is there or not or not seems... difficult.

Depends on distance, angle, and lighting but they’re definitely visible from another aircraft. (Source: former c-130 flight engineer)

Here's a picture of the first us jet fighter prototype next to a propeller fighter, you can definitely tell a difference.

You can't see individual blades, but you can absolutely see the disc the propeller forms. Same with helicopters.
