REFLECTOR: Aileron cables for side sticks

[Patrick Sieders]

Reiff,

 

I would certainly back it up with the connecting rod. That would make it
failsafe.

 

I believe your 3rd option would be the best in this case. I am worried about
the turns though, but see no other way around it. The more and sharper the
turns, the heavier the cable system will eventually become.

 

I am still interested in the outcome of this. Although at this point I am
still leaning towards the steel torque tube system to feed to the whale
tail. I am planning to have my aileron servo there. And it also alleviates
finding a good route on each side of the wall to route the cables.

 

But I will keep following the advancements !

 

Thanks !

Thanks, everyone, for the comments. I didn't put the interconnect in the
drawings. The standard side-stick kit comes with rods that connect each
stick to the torque tube in the keel. This also serves as the interconnect
between the sticks. It seems best to keep everything interconnected by
running a rod directly from stick-to-stick between the avionics stack and
the canard; which is also what Velocity HQ did on the twin.

 

Or maybe take out the interconnecting rod and allow deploying flaps by
moving the left stick right and the right stick left! :-)

 

Any other thoughts?

All,

 

I don't see the interconnection anywhere in any of these three designs.  One
thing to consider is according to how you do the inter connection, the
apparent length goes from the length of one cable to the combined length of
both cables and can actually make the drag unacceptable.  This would happen
if you chose option three with a connecting cable between the airleron
torque tubes.  Any way you connect two long cables you will still have
significant drag.  Another consideration is the flutter characteristics due
to the addition of elasticity with two long cables.

 

Just my thoughts.

I've chatted with a number of builders in the past few weeks in the Velocity
Builders' Virtual Hangar. I've discovered that a number of us are installing
the side-stick option and want to eliminate the torque tube in the keel.

 

Scott Swing has indicated a willingness to think through an alternative
connection method for us, probably involving control cables that run all the
way from the sticks to the wing root. A few options are presented in the
attached PDF. These are my sketches and thoughts, not Scott's, and I'd love
the community's input. I'm leaning toward #3, since it has the fewest parts
and takes the least design / re-engineering, but might be talked into one of
the other options if it is safer, easier, or philosophically more elegant.
:-)

 

Let me know what you think. Also, please contact me (directly is OK) if you
too are interested in a more direct connection for your side-sticks so I can
tell the factory how many of us there are.
