Claim 6:
7. A drive system for translating a translating sleeve of a thrust reverser of a nacelle relative to a fixed structure of the nacelle, the drive system comprising:
a first primary actuator including:
a first primary rod configured to attach to the fixed structure; and
a first primary gear rotationally coupled to the first primary rod;

a torque shaft rotationally coupled to the first primary gear;
a secondary actuator operationally coupled to the first primary actuator via the torque shaft, wherein the secondary actuator is configured to rotate a blocker door of the thrust reverser between a stowed-blocker-door position and a deployed-blocker-door position in response to rotation of the first primary gear, wherein the secondary actuator comprises:
a secondary gear rotationally coupled to the torque shaft; and
a secondary rod including a plurality of teeth configured to engage the secondary gear, wherein the secondary rod is configured to rotate the blocker door in response to rotation of the secondary gear,

wherein the first primary gear is configured to translate linearly relative to the first primary rod in response to a deployment of the translating sleeve.
