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.
A thrust reverser system for fan jet type aircraft gas turbine engines using a rack and pinion arrangement for moving blocker doors between the stowed and deployed positions. Blocker doors fill a plurality of circumferentially arranged openings.
A thrust reverser having an annular duct bounding a bypass flow and including a set of vane cascades configured in a stationary pod portion, a displaceable fairing slidably mounted on the stationary pod portion to permit sliding motion along a slotted cylindrical shell and to be translated between a stowed position blocking access of the bypass flow to the vane cascades and a deployed position wherein the vane-cascades are exposed to the bypass flow, a drive system driving the displaceable fairing, and flaps arranged to seal the annular duct in order to deflect a flow toward the vane cascades. The drive system further includes linear actuators substantially configured in the central axis of the slotted cylindrical shells.
