Bell/Hiller - Flybar System
BELLs: Helicopter control system which used a bar with weights on the ends
mounted 90° to the main rotor to gyroscopically stabilize it.
HILLERs - Hiller-Matic Paddle System
The Hiller aerodynamic paddle design requires very little effort to change the cyclic pitch of the rotor and
self-correcting, but there is lag*) between control input and the flybar changing the rotors. *)delay prodleva
http://super.nova.org/RC/BellHiller/index.htmlHiller's design was incorporated into the H-23 / U-12 flow in the Korean War
and popularized by the TV series MASH.
The first successful RC model Helicopters which appeared in the late 1960s were variations on Hiller's paddle design flown by by Dieter Schluter. In the mid-70s RC models began to use a combination of the two systems, grafting a heavier version Hiller's airfoil paddles to the gyroscopic stabilization bar
concept of the Young/Bell design.
Při použití "ne lehkých (těžších)" pádel na koncích flybar dojde k mixu vlastností obou systémů.
