Abstract:

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