|Quoting BHMBAGLOCK (Reply 3):|
It's a bit different on a CH-46/7 in that the shaft always carries half the power(on average); this is its primary role. In a tilt-rotor, the primary role of the interconnecting shaft is to synchronize the two rotors. In the case of an engine failure it is capable of transferring power between nacelles for the duration of the emergency but is not designed to take the associated loads continuously.
Doesn't the shaft also serve the same purpose in the CH
-46 and CH
-47? I thought that the rotor arcs between the front and rear rotors actually crossed, and that this was possible because the rotor blades were synchronized...of course, I may be mixing up the Boeing Vertol/Piasecki system with the Kaman rotor system
