Anti Torque on CH-46-47

[jjsemperfi]

So I heard from a CH-47 crew chief that to make a pedal turn the blades will actually change their lift vectors by tilting the disk. I've always wondered how they work. Anyone know for sure?

These people seem to agree

Find yourself a copy of FM 3-04.203 (Army Fundamentals of flight....I think available online). It's got pictures. (and is pretty convenient for other stuff as well.....)

 

Link seems to explain pretty well...

Anti torque pedals are cyclic inputs.

And the complexity of the control tubes, bell cranks, and mixing units is enough to make your head spin.

Spin. LoL nice.

Think the mixing unit is complicated on a 46? Look at the mixers on a CH-53E. The thing I hated most about the CH-46E was removing the yokes for phase and changing the hell crank. Literal hell right there.

The Chinook is not that bad... then again... I've been working on them for 10 years... The flight control rigging on the Chinook is actually quite simple compared to a Blackhawk. I've worked on both, and I would much rather rig a Chinook!

I hated H-60 controls, but they are simpler than the 53E, just more finicky. I can't remember how many ships we chased popping and clicking on at Sikorsky.
