A turbine engine having two contrarotating unducted propellers, an upstream propeller (12) and a downstream propeller (14), with a power turbine mounted axially between the two propellers (12, 14), the turbine comprising an outer rotor (56) constrained to rotate with the upstream propeller (12) and an inner rotor (54) driving rotation of an inlet shaft (62) of a step-down gearbox (52), the gearbox having an outlet shaft (64) driving rotation of the rotor (56) of the upstream propeller (12) and an outlet shaft (66) driving rotation of the downstream propeller (14). |
