Bryan - perhaps it is you who is wound too tight:) I didn't say the MR and TR were not propellers in the strict definition of one - just that nobody in the rotary world calls them that.

Nobody calls the rotor a 'vertical propeller' and translating tendency is a term of US origin, it is better understood when called tail rotor drift, with tail rotor roll the description of the...

It would seem that physics isn't much use where helicopters are concerned since they never stay still once running so static diagrams don't help.

ISTR the people that investigated the 2 Sea King...

So are you saying that I am correct when the aircraft is moving but you are correct when the aircraft is static?

But those couples/torques must be acting around a point to have created the rotation until equilibrium is reached.

As far as rotor design goes - with a teetering head, the fuselage just hangs under the rotor so you tilt the disc and the fuselage obediently follows it. When you add hinges (physical or virtual) you...

Syd, thank you for your answers but surely there has to be an axis of rotation if the body rotates.

Consider just the translating tendency of the TR thrust before the disc is tilted to compensate...

OK Syd, a genuine question for my education:

We have been discussing couples that create rotation of a body - how do you identify the axis of that rotation? Is it along the line between (in this...

Not sure you are right about that - you need a point for a force to work around or opposing forces to create a couple - a pivot point essentially, and that is the C of G.

Force x arm = moment

The right roll in ACs diagram (opposing TR roll) is a result of the arm between the action of the TR thrust and the vertical position of the C of G. All forces act around the C of G whether it be...
