摘要： A door roller mechanism (214) for cooperation with a roller track (212) including a carriage member (215) having a door attachment feature (217); at least one roller (216) disposed for rotation on a first side (215f) of the carriage member (215) when the carriage member (215) moves in the rolling direction (RD); at least one roller (216) disposed for rotation on an opposite second side (215d) of the carriage member (215) when the carriage member (215) moves in the rolling direction (RD); a first rub member (230) disposed on the first side (215f) of the carriage; a second rub member (232) disposed on the second side (215d) of the carriage; and at least one biasing element (234) disposed on the carriage member (215) for resiliently biasing the first rub member (230) and the second rub member (232) in opposite lateral directions so as to contact a respective first track surface (320d, 322d) and a second track surface (320e, 322e) in a manner to dampen lateral vibration of a door (204) connected to the roller mechanism (214).

摘要： One example of a tiltrotor aircraft (100) includes a rotor system (110a, 110b), a pylon (102a, 102b) coupled to the rotor system (110a, 110b), a spindle (112) coupled to the pylon (102a, 102b), an actuator arm (114) coupled to the spindle (112), and an actuator (116). The actuator (116) can cause the actuator arm (114) to rotate, thereby causing the spindle (112) to rotate the pylon (102a, 102b) and the rotor system (110a, 110b). In an example, the actuator (116) is in front of a forward spar (122) of the wing (104) of the tiltrotor aircraft (100) and the actuator arm (114) is about one-half (0.5) of an inch (1.27 cm) to about five (5) inches (12.7 cm) from the wing (104).
