Abstract
A jet engine is conventionally housed in a streamlined nacelle having a rwardly tapering aft-section ending with a trailing edge surrounding the jet propulsion nozzle and presenting ahead of it one or more side outlets for issuing the engine exhaust flow when laterally deflected from said nozzle upon actuation of the thrust-reverser system. This tapering aft-section thus presents a rear annular peripheral zone extending between its side outlets and its trailing edge and having a continuous outer surface subdividable into peripherally alternate segments which lie respectively in longitudinal rearward extension of a side outlet and of an intermediate solid span between consecutive side outlet edges. A controllable nacelle streamlining destroyer is fitted adjacent said solid span in order to project outwardly therefrom into the relative boundary airflow a thin sheet-like obstacle intercepting stream-lines thereof and causing them to separate from the following stretch of the nacelle aft-section outer surface.
