Abstract
A turbine engine including two respectively upstream and downstream external impellers that are nonstreamlined, coaxial, and contrarotating is provided. The downstream impeller is retractable so as to reduce its diameter. The blades of the downstream impeller are mounted so as to pivot about a pivot, the axis of which forms a nonzero angle, notably perpendicular, with the axis of rotation of the impeller, the blades in the retracted position being tilted about the pivot.
