Thrust reverse for a turbofan engine

机译:涡扇发动机的反推力

摘要

A thrust reverser includes a thrust reversing door having maximum efficiency in both the closed, forward thrust position and the open, reverse thrust positions. An inner panel is pivotally attached to the thrust reverser door by a linkage mechanism such that, in the closed position, an interior surface of the inner panel is substantially flush with the interior surfaces of the housing defining the cold flow duct so as to minimize or eliminate any perturbations in the air flowing through the cold flow duct. When the door is moved to the opened position, the linkage mechanism interconnecting it to the inner panel causes the inner panel to pivot a greater amount so as to bring an upstream portion of the inner panel closer to an upstream portion of the door to expose the deflector and thereby increase the thurst reversing efficiency. The linkage mechanism interconnecting the inner panel with the door is completely contained between these elements and is also interconnected with the door actuator such that the actuator motion in moving the outer door between its opened and closed positions also serves to move the inner panel.
