The invention discloses a periphery type electric propulsion jet engine system and a design method, and belongs to the technical field of engines. The periphery type electric propulsion jet engine system comprises a duct unit, a motor unit and a fan blade unit. The duct unit is of a hollow columnar structure. The motor unit comprises a motor rotor and a motor stator. The motor stator is fixedly arranged in the duct unit, and the motor rotor is correspondingly arranged on the inner wall of the motor stator. The fan blade unit is arranged in the inner wall of the motor rotor and fixedly connected with the motor rotor. The motor rotor rotates and can drive the fan blade unit to rotate, and accordingly force in the axis direction of the duct unit can be generated. The periphery type electric propulsion jet engine system adapts to electric propulsion, and is simple in structure, small in integral structure weight and high in pneumatic efficiency.
