Spinner strobing as a "Bird Strike Countermeasure"
Roger (K8RI) writes:
At cruise RPM that effect would be completely lost. There's not a bird or human alive that can discern stroboscopic effects of more than a couple hundred cycles let alone over a 1000. Most of us can't even discern 60 cps. Birds have much better vision than human beings, and I don't believe anyone has tested their ability to discern stroboscopic effects. And the front fan on a turbofan is turning at around 40-50 revolutions per second, not thousands.
