Actuation system for controlling movement of doors

摘要

An actuation system ( 44 ) for controlling a first door ( 38 ) and a second door ( 40 ) includes a first actuator ( 72 ) having a first interior passage ( 74 ) and a second actuator ( 76 ) in line with the first actuator ( 72 ). A first shaft ( 82 ) extends from the first actuator ( 72 ) and has a second interior passage ( 86 ). A second shaft ( 88 ) extends from the second actuator ( 76 ) and is directed through the first and second interior passages ( 74, 86 ) to exit from the first shaft ( 82 ). The first shaft ( 82 ) is in communication with the first door ( 38 ), and the first actuator ( 72 ) drives the first shaft ( 82 ) to move the first door ( 38 ). The second shaft ( 88 ) is in communication with the second door ( 40 ), and the second actuator ( 76 ) drives the second shaft ( 88 ) to move the second door ( 40 ) independent from movement of the first door ( 38 ).
