Spinner strobing as a "Bird Strike Countermeasure"

Hence the reason an aircraft propeller will
appear to be revolving slowly backwards at times.

Not when being observed directly. That only happens in movies and video
due
to the interaction between the imaging rate and the rotation rate of the
propeller.

Wrong again you clueless twit.



No, he is right this time.

Do you really think you see and visualize motion constantly. Perhaps
you should spend a little more time around and airport yourself. Many
propellers, especially the large diameter props found on radial
engines, will appear at times to be rotating slower, or backwards.
It's a fainter image than recorded on film, but the partnership of
the human eye and brain does not realize fluid motion.

This is completely incorrect. Human vision produces no such artifact.
Anything moving beyond a certain speed is simply a blur; it never
appears to move backwards.



Too easy

My phonograph turns at either 33-1/3 or 45 RPM, which is just as
relevant to this conversation as your mention of turbofans.

At any given moment there are thousands of aircraft powered by
turbofans in flight.



None of which you are on.


Ever

The original assertion was that it was an artifact of human vision, which
is
never true.

Keep digging, and guessing. God you are stupid.

No, motion pictures PRODUCE the phenomenon. It's an artifact of the
motion
picture, not human vision.

That is a function of shutter speed.

No, the human visual system will not do it at all.

Keep digging, you are half way to China already.

Of coarse it is, you prove yourself as clueless as ever. You and your
friend AirBuzz need to do your home work. Your unwillingness to experience
the real world has left you short of observing such a thing with your own
eyes.

Get out of your basement and go to the airport. This phenomenon is apparent
to the naked eye under continuous lighting conditions. You might need to
wait for a three or four blade prop, but it DOES happen in real life.
Something your prove once again you know little or nothing about.

Priceless, thanks for a really good laugh.
