Abstract
A duct for evacuating hot air from an aircraft engine is extended by a movable stack that can project from the wall such that the hot air is ejected a distance from the wall without risk of damaging the wall. The stack can, however, be retracted by a control device under circumstances of moderate engine speed, with the advantage that the drag of the wall, generally an outer nacelle, is then reduced.
