Some time ago I found an article on the Scheutzow Stork. I have been doing alot of research on it. I have found everything I could, even did patent searches (in one of the articles it mentioned he was seeking new patents on the head design).

I posted a question here and asked if anyone was familar with the guy or design. Chuck Beaty had said he met him at Oshkosh before Scheutzow had his heart attach (if I remember right, correct me if I am wrong Chuck). The reduction unit used was from Chuck's design for his 3 bladed helicopter from the 70's? (again if I am wrong Chuck correct me.) Other than that no other information. I kept searching though.
Still nothing new so I am hoping someone on here can if possible clear up some questions with either explination and or also with pictures?
I am mainly in question about the head design.
1. How can you set it up to where when throttle is applied the rotors go to fixed positive pitch and throttle/rpms provide the lift and when throttle is reduced the blade pitch returns to autorotational settings?
2. It was explained in the article that the blades are mounted rigidly in plane, with an offset flapping hinge and Delta 3 of 15 degrees. Can not picture in my head how you would do this?
3. I understand that the rigid in plane mounting of the main rotor was to give better control response since it is weight shift controlled and to be able to use a short main rotor mast. But wouldn't this also dramatically increase the strain on the rotorblades? What is the advantage?
4. I believe the Delta 3 is to control blade flap to prevent collision with the airframe?
5. Offset flapping hinge I think is to allow more control power thru the center of gravity?
Thanks for the help guys,
