A fan thrust reverser includes an outer louver door joined to an inner blocker door by a drive link in a bifold configuration. The louver door is stowed closed in the outer skin of a fan nacelle outside the blocker door stowed closed in the inner skin of the nacelle. An actuator deploys open the louver and blocker doors, with the louver door extending radially outwardly and the blocker door extending radially inwardly for reversing fan exhaust flow during thrust reverse operation.

Bifold door thrust reverser

A thrust reverser includes axially adjoining forward and aft cowls defining a fan nacelle for surrounding a fan and core engine with a fan duct therebetween. The aft cowl has a forward face and the forward cowl has an aft face adjoining each other to define a reverser nozzle which converges radially outwardly. The aft cowl is translatable between a stowed position in which the reverser nozzle is closed and a deployed position in which the reverser nozzle is open for discharging fan air in a forward direction for thrust reversal.

Converging nozzle thrust reverser

A thrust reverser includes a pair of doors covering corresponding portals in an exhaust duct between an inlet and outlet nozzle at opposite ends thereof. The duct also includes a pair of side beams having actuators mounted thereon, and operatively joined to the doors for selective rotation thereof about corresponding pivots. Blister fairings are disposed inside the duct and sealingly join the doors to the beams around respective ones of the pivots.

Pivot fairing thrust reverser

A hinge arm for a thrust reverser door may be mounted to an exhaust nozzle using an aft mount. The mount includes a frame for attachment to the nozzle. A swing link has a first pin pivotally joined to the frame, and a second pin for pivotally joining the hinge arm to the link to permit both swinging and pivoting of the hinge arm from the frame. The aft mount thusly permits the reverser doors to be reliably stowed around the nozzle.
