ABSTRACT:
A wall of a multi-flow turbojet-engine thrust-reverser cold-flow duct defines an air intake for a main air takeoff (F'.sub.1) and an additional secondary air takeoff (F'.sub.2) which assures the suction of the boundary layers of the flow. The secondary air takeoff may consist of a transverse slit. The takeoffs may be used to supply cooling, pressurizing or ventilating air to the airplane or hot engine part.
