摘要： An aircraft includes a pylon rotatable relative to a wing, a proprotor assembly carried by the pylon, the proprotor assembly have a proprotor blade that is foldable to a stowed position extending substantially parallel to the pylon, and a fluidic clamp positioned with the pylon and configured to grip the proprotor blade when in the stowed position, the fluidic clamp including a first inflatable bladder positioned on a first side of an opening for receiving a portion of a proprotor blade and a pressurized fluid source in fluid connection with the first inflatable bladder.

摘要： Embodiments are directed to a selectable drive system that allows a rotor gearbox to send torque to a proprotor assembly and/or through a multiplier planetary gear set to a pylon-mounted ducted fan thrust unit. The rotor drive system may be a stop-fold system in which rotor blades can be folded when not rotating. This allows a normally idle lift engine to provide additional aircraft thrust during cruise where an aircraft is typically using only a dedicated thrust engine for high speed flight. An inline engage/disengage actuator or “shift fork” on the rotor gearbox is used to select the torque-output direction. The multiplier planetary gear set increases the output RPM that is received from the rotor gearbox and that is applied to the thrust fan unit.

摘要： An exemplary clamp system for securing a proprotor blade in a stowed position includes a clamp having a pair of opposing pads operable between an open position to receive a portion of a proprotor blade between the pair of opposing pads and a closed position to grip the portion of the proprotor blade with the pair of opposing pads and a rotary actuator in connection with the clamp to operate the clamp between the open and the closed position.
