Abstract
For a long dual mixer nacelle housing a fan-jet engine powering aircraft, a pair of concentric sleeves sandwiching the cascades to effectuate thrust reversal are synchronously deployed axially to communicate the fan discharge air in the duct with ambient through the cascades. A rack and gear connection between sleeves permits the independent linear motion of each of the sleeves so that the actuation of one automatically actuates the other without the necessity of attaching both to each other.
