Abstract: A tiltrotor aircraft (10) having a VTOL flight mode, a forward flight mode and a storage mode includes a fuselage (12) having a wing (18) rotatably mounted thereto. The wing (18) has an orientation generally perpendicular to the fuselage (12), in the flight modes, and an orientation generally parallel to the fuselage (12), in the storage mode. First and second pylon assemblies (22a, 22b) are positioned proximate outboard ends of the wing (18). First and second mast assemblies (24a, 24b) are respectively rotatable relative to the first and second pylon assemblies (22a, 22b) and have generally vertical orientations in the VTOL flight mode, and generally horizontal orientations in the forward flight mode and the storage mode. First and second proprotor assemblies (26a, 26b) are respectively rotatable relative to the first and second mast assemblies (24a, 24b). Each proprotor assembly includes a plurality of rotor blades (52a-f) and has a radially extended orientation, in the flight modes, and a stowed orientation, in the storage mode.

Abstract: A vibration isolation system (208) for an advancing blade concept rotorcraft (200) having a pylon assembly (202) and an airframe (222). The vibration isolation system (208) includes one or more pylon links (210; 212) each having first and second ends with the first end (214; 216) coupled to the pylon assembly (202) and the second end (218; 220) coupled to the airframe (22). Each pylon link (210; 212) includes a vibration isolator (228; 230), such as a Liquid Inertia Vibration Eliminator unit (232), that is interposed between the pylon assembly (202) and the airframe (222). The vibration isolator system (208) is operable to reduce or eliminate transmission of the pylon assembly (202) vibration to the airframe (222).
