All of the helicopters by Sikorsky using their X2 technology coaxial rotor system don't seem to have a conventional swashplate and control rod assembly for controlling the pitch of the rotor blades. At least none that is visible from the outside.
All of the X2 technology helicopters are fly by wire, according to Sikorsky so each blade might be fitted with an individual actuator, but I couldn't find any detailed explanation of how the whole rotor setup works.
This theory might also be supported by the sliding contacts between the rotating system of the upper and lower rotor visible in the picture below, but these could also just be there for sensors, anti ice or else.
Does anyone have concrete knowledge on how the Sikorsky X2 rotor system works?
