CT: The bucket target system is hydraulically actuated and uses bucket-type doors to reserve the hot gas stream. The thrust reverser doors are actuated by means of a conventional pushrod system. A single hydraulic actuator is connected to a drive idler, actuating the doors through a pair of pushrods (one for each door).
