초록 ▼

A thrust reverser for a turbofan-type turbojet engine is disclosed having an inner housing with a rear, downstream edge, a fan cowling extending around a portion of the inner housing so as to define a bypass gas flow duct, the fan cowling having a rear edge portion disposed forwardly of the rear edge of the housing. The thrust reverser also includes a thrust reverser flap assembly having a carriage slidably connected to the rear edge portion of the fan cowling so as to move in an axial direction between first and second positions, a thrust reverser flap having a rear flap edge disposed forwardly of the rear edge of the inner housing and pivotally attached to the carriage, and a link rod pivotally connected to the thrust reverser flap and to a stationary structure such as the inner housing. When the carriage is in its first position, the thrust reverser flap is in a forward thrust position wherein an outer surface of the thrust reverser flap is flush with the outer surface of the fan cowling and, when the carriage is in its second position, the thrust reverser flap is in a reverse thrust position wherein it redirects the gases passing through the bypass duct in a reverse thrust direction.
