Variable outlet section air flow ejection nozzle and turbomachine equipped with such a nozzle.

Abstract

A turbomachine airflow ejection nozzle (19), particularly for an aircraft, extending on one side around a longitudinal axis (X) and on the other side between an inlet section (20) and an outlet section (21) along the longitudinal axis (X), the ejection nozzle being delimited at least in part by an external radial ferrule (24) and an internal radial ferrule (25) forming at least in part a flow channel (18), the ejection nozzle comprising a series of struts (45) arranged regularly around the longitudinal axis (X) and extending radially between the external radial ferrule (24) and the internal radial ferrule (25), wherein each strut (45) of the strut series is movably mounted on the internal radial ferrule (25) with a degree of freedom so as to modify the output section.
