Swishring

UniCopter ~ Control - Flight - Swishring *

Overview:

A means of locating the flight control device (ref swashplate and spider) inside the rotor hub; to decrease drag and reduce the vertical clearance between hub and fuselage.

The Swishring could be an inflexible and thereby serve the basic 1/P control function.

Alternatively; -

A means of providing Higher Harmonic Control.

A circular track, located in the rotor-hub, within which, or about which, cam followers move. The cam follower is linked by an arm to the blade so as to affect the blade's pitch. The plane of the swashring can be tilted and thereby impart a 1/revolotion cyclic to the blades. As well, it can be vertically deformed and thereby impart harmonic higher than 1P to the blades.

A ring with a 'C" profile with the opening facing outward. A type of cam-follower is located at the pitch link end of each pitch horn and these cam-followers run inside the 'C'.
Alternatively; a singular circular ring. The pitch link has a two cam assembly where one cam is located above the ring and the other below the ring.

This concept might be employed on the root control of the Independent Root & Tip (IRAT) concept.

* Origin of the name Swishring.
