The invention discloses a boundary layer suction type propulsion system and an aircraft. The propelling system comprises an open type rotor engine and a BLI fan. Wherein one part of energy of fuel combustion of the open type rotor engine is used for driving a rotor of the open type fan to rotate to serve as propelling power, the other part of fuel chemical energy is converted into electric energy and transmitted to the BLI fan installed on the rear portion of the fuselage, and the electric energy drives the BLI fan to rotate to provide the other part of propelling power; wherein the BLI fan comprises a fan hub, a motor and a shunt ring; and the shunting ring is arranged at the upstream end of the fan hub and is used for guiding part of airflow to pass through the motor so as to cool the motor.
