The double-propeller aircraft (1) comprises a fixed wing structure (2, 3, 4) for the flight of said aircraft (1) and at least a propulsion system (5), wherein the propulsion system (5) comprises: - a first piston engine (6) to put a first drive shaft (7) in rotation around a first axis of rotation (A) substantially horizontal; - a second piston engine (8) to put a second drive shaft (9) in rotation around a second axis of rotation (B) substantially horizontal and parallel to the first axis of rotation (A); - a first propeller (17) keyed on the first drive shaft (7); - a second propeller (21) mounted idle on the first drive shaft (7), the first propeller (17) and the second propeller (21) being coaxial and counterrotating the one to the other with respect to the first axis of rotation (A); - transmission means (27, 28, 29) interposed between the second drive shaft (9) and the second propeller (21) for the transmission of motion from the second drive shaft (9) to the second propeller (21).
