Question

hello dave, lu

dave, help

i must give out and admit i dont get it,
explain it to me please in simple words....

double join as teetering device, undersling or not, ok

what i really dont understand, is why no need for lag, flap
specially in fw flight, i may be poor understanding it, but, the drag forces on the blades are not symetrical ?,

lets take 4 blades, in a 12 - 6 hrs config the advancing blade generates more drag than the retreating one, do you think in the d3 angle to reduce it ?

that would mean that (according to your design) if i imagine a simple spherical bearing as rotor hub (admitting it's magically powered) i just can mount rigid blades without flap lag articulations, all we should need is a conical, or symetrical damping.... right ?

if so, you know what i have in mind

mayday dave, lu

thank you
