Centrifugal turning moment vs. blade pitch angle.

[Focha]

Hi there,

I am having a hard time figure this out. Maybe it's a question of technical designations.

What I want to know if possible is why centrifugal turning moment tends to decrease the blade pitch angle?

Thank you a lot for your help.

Best regards.

You can try looking at this excerpt from Phil Croucher's book on google books.

That should bring up a page which helps to explains it.

I'd recommend the actual book...

Thanks a lot for the help. It explained what I was looking for. The book indeed seems really interesting. Is the title "The Helicopter Pilot's Handbook"? I only find that from Phil Croucher.

EDIT: I found it. Professional Helicopter Pilot Studies, thanks a lot for the help.
