Turbojet ejector nozzle for aircraft, especially of vertical take-off or landing type, has transversely movable shutter projecting through ejector opening, to vary distribution, width and aeration of ejection section

摘要

An ejector nozzle for an aircraft turbojet, with a longitudinal central axis and a pipe (32) with side-walls (34, 36) ending in an ejector opening (38) in the axis plane, has a shutter (40) in the nozzle, projecting outwards through the opening to define the nozzle final ejection section (A). The shutter is movable tranversely in the opening plane (P), to vary the distribution of the ejection section transverse to the opening, modify width and vary aeration of the ejection section.
