Air-discharge device for an airplane turbofan engine

摘要

The device (20) has a rotating door (24) comprising inner and outer flaps (26, 28) secured and articulated around a pivot axle (58) that is remote from the inner flap in a direction from the outer flap to the inner flap when the door is in closing position so that upstream and downstream ends of the inner and outer flaps protrude from inner and outer sides relative to inner and outer surfaces (12, 14) of a fixed structure (22) in opening position. The inner flap is spaced from the structure to provide an air passage between the inner flap and the structure in downstream of the inner flap.
