B199

MAKE: SynchroLite ~ Control - Flight - Mixer Box

  

Movement at Mixer Box

Collective

Vertical movement will be: 0.3960" * 2 = 0.7920" total.

Angular movement of control tubes will be: Sin (0.7920 / 54 [+/-]) = 0.8404 degrees

54 is the approx. length of the yaw tube.

Yaw

Cyclic - Longitudinal 8 degrees

Cyclic - Lateral 

Lateral Cyclic

Like the Husky perhaps the design should have the rotor ont the outside of the turn have less lateral movement than the inner one so that the blade does not strike the hub. Drawing [Rotor - Disk - Blade to Hub Clearance] 0442 shows this clearance.

 

Movement at Cyclic Stick

Vertical movement will be: collective vertical movement at mixer box of 0.7920" * (21 / 54) = 0.3080". 0.1540" in both directions.

Rotational movement will be 8 degrees in each direction for a total of 16 degrees. I think. 

Idea December 15, 1999

Angle of arms in mixer box that are connected to longitudinal cyclic should maybe be changed so that the rotor disk that is tipped backwards has a little more movement then the one that is tipped forward. During yaw, the rotor disks will give a small amount of 'nose up" which will offset the 'tail up' caused by the ruddervator because the plan view surface area will decrease slightly as the ruddervators pivot about their axis for yaw also.

Mounting of Rear of Tubes

There will be movement between the fuselage and the drive train because of the isolation mounts. It might be better to have the rear end of the two control tubes mounted to the drive train and not the back of the fuselage tube.
