Hi Dick,
Right around 700 FPS, or 475 MPH. That's rotation speed. On the advancing
side of the rotor, at maximum forward speed (Vne), it's about 650 MPH; on
the retreating side it's only about 300 MPH. As you can see from that,
helicopter aerodynamics get pretty complicated, pretty fast.

Subject: Helicopter blade speed ? ?
Just out of curiosity - - what is the mph speed
of the tip of the blade as it rotates?
