The embodiment of the invention discloses a foldable rotor system for a high subsonic velocity tilt rotor aircraft, relates to the technical field of high-speed vertical take-off and landing aircrafts, and can reduce air resistance while realizing the functions of rotation, pitch change and folding. The foldable rotor mainly works in an unfolding mode and a folding mode, has rotational degrees of freedom in three directions, and can achieve the functions of rotation, pitch change and folding. When the high subsonic velocity tilt-rotor aircraft vertically takes off, lands and flies in a rotor wing mode, the rotor wings of the high subsonic velocity tilt-rotor aircraft are unfolded and are similar to a rotor wing system of a tilt-rotor aircraft; when the high subsonic velocity tilt rotor aircraft flies in a jet mode, the engine is switched into a turbofan mode, meanwhile, the rotors are folded backwards to reduce resistance, and high-speed cruise is achieved. Therefore, air resistance can be reduced while the functions of rotating, pitch changing and folding are achieved.
