The invention is suitable for the technical field of aircrafts, and provides a rotor wing device with a variable pitch and a multi-rotor-wing aircraft. The rotor wing device with the variable pitch comprises a power device with an output shaft, at least two propellers and a transmission assembly, wherein the transmission assembly is provided with at least two rotating shafts, inclined angles are formed between the rotating shafts and the output shaft; the power device rotates at an accelerated speed or a decelerated speed on the basis of constant speed rotation, and the propellers are driven through the transmission assembly to perform deflection movements around the rotating shafts, so that inclined angles between propeller blade section strings of the propellers and rotary planes of the propellers are changed. According to the rotor wing device with the variable pitch disclosed by the invention, the power device rotates at the accelerated speed or the decelerated speed on the basis of constant speed rotation, deflection exists between the propellers and the transmission assembly because inertia effect, so that pneumatic attack angles of the propellers are further changed, and the size of the lifting force of the propellers at the moment is changed; the rotor wing device with the variable pitch is simple in structure and high in reliability.
