Zusammenfassung:A mast for connection between a power plant and the rest of an aircraft that includes an outside surface ( 14 ) that is in contact with the air flows, characterized in that it includes, in the outside surface ( 14 ), at least one recess ( 22 ) that is blocked by a porous wall ( 24 ), with a porosity of 3 to 6%, coming into the extension of the outside surface ( 14 ), whereby the recess makes it possible to have the high-pressure zone ( 18 ) communicate with the low-pressure zone ( 20 ), zones that are arranged on both sides of a shock wave ( 16 ).
