Tip Path

FlightOops

Thinking back at Nick's analogy of defining MSL by filtering out the ocean waves, the tip path is obtained by filtering out higher order bending and flapping harmonics.

So, one way to obtain the simple and clear picture, you refer to, is to restrict the flapping to the first order harmonic behaviour (that is those sin-waves that have the same frequency as the MR).

So the tip plane is defined by the first order flapping harmonic.....


did it again.... cheers...
