There would still be a small amount of torque due to bearing friction at the hub. Not much though, which is why the rotor can be so close to the pilot and not spin very fast.
-
stolen idea from Gilbert Magill in 1954
-
There is no torque caused by the rotor, the tail rotor acts only as a rudder.
-
is the fuselage made of wood?
-
why is there still a tail rotor? Because there isn't a rudder?
-
hahaha god flies without rotors
-
How long could you stay airborn ? and what's the fule consumption ?
-
Germany was using this technology in WW2. It's incredible and interesting. I thought the design made no torque, but the tail rotor on this copter means that's not the case.
-
absolutely amazing!!!! didn't think you were going to take off initially
-
On second thoughts - blade tip propulsion = no torque! Hover rotation by rotor shaft clutch? I've got to get one ...
