Abstract
A turbine has a first rotor and a second rotor configured to pivot about a longitudinal axis (X) according to two opposite directions of rotation. The first rotor has a radially outer drum from which blades extend radially inwards. The first rotor and the second rotor are surrounded by a stator annular part. The stator annular part delimits, with the drum, at least one upstream annular cavity and one downstream annular cavity separated from each other by sealing means.
