Twin screws

How do you figure it out in real life, without going into classified stuff?

Taking a common sense approach here… :hmm:

I like to think of this like playing a guitar through a guitar amplifier, same frequency(fundamental) but ‘twice’ gain (sound)

That said, I would think the DEMON display on twin shafts would be the same, but the freq lines on twin shafts would display 2x amplitude(brighter) since you have two shafts(twice propeller noise) spinning at the same frequency (rpm)

I would also think that since both shafts will be spinning at same (rpm) on a direct course, if not you’ll suffer inefficiency in propulsion(drag). But while going into turns, (rpms) could vary to give up better handling, if so then the frequency lines could alter for a brief moment of time.

Just a thought…
