In a vertical descent with the engine switched off, everything would be vertical. If the machine was trimmed to resist torque roll in normal forward flight, some sideward stick pressure would be necessary to counter the trim springs.
And on sum machines [ the ones with dunny door sized HSs] youd also need sum back stick, to hold the nose up.
Iv lerned alot for you over the years CB, but this thing bout roll trimm to counter sumthn you say is comen from the rotor aint sinkn in.
Iv been assup for abit with the flue, so iv had plenty of thinkn time, but still no go.
Was thinkn bout the similarity between our rotors and our blackfellas bent sticks [ boomerangs]. But it still didnt help.
If our rotors took off without us [ rotor bolt let go] theyd follow the same parth as the bent stick, ie; theyd turn back, to the left. [ if spun in the same direction as our rotors].
The higher AS on the advancing blade of the rotor [ and the bent stick] will mean it wants to fly in circuls.
This would imply that theres a cyclic input all the time for us to hold our streight flight parth, which we all know is the teeter action.
But, the teeter action only allows for each blade to balance eachothers different ASs by changing their AOA, which balances the lift, so we can fly streight.
Teetering acts lateraly, and so dose the teeter hinge, so how the hell can it force anythn through the stick?
Even with lateral flapping, to fly straight, the rotor thrust vector must point straight up.
Thats logical.
To make it do this, you have to hold a bit of opposite stick that tilts the rotorhead over a bit.
Why?
I thought the teeter was do'n it for us.
In a machine with a ridged rotor and swashplate i could understand why youd have to counter it with stick position, but we have a teeter hinge to do it for us.
Sorry CB for my dumness, but i cant grasp where this [ margional] force is comen from.
