The invention belongs to the field of vibration control, and relates to a self-adaptive torsion damper and an aircraft which are used for variable-speed helicopter rotors, torque transmission paths and transmission systems, and the damper is characterized in that the inner wall of an outer ring is connected with the outer wall of an inner ring of a center hole through N groups of centrifugal grooves; the center ring is installed on the rotating component through the center hole inner ring and rotates together with the rotating component. N is a natural number greater than or equal to 2; n groups of first-stage springs, N groups of second-stage springs, N groups of second-stage mass blocks and N groups of friction mass block assemblies are arranged in the N groups of centrifugal grooves respectively; one end of the secondary spring is connected with the outer wall of the inner ring of the center hole, and the other end of the secondary spring is connected with the inner side of the mass block; the outer ring is provided with an annular groove penetrating through the inner end face and the outer end face of the outer ring, and the inner friction ring is arranged in the annular groove, connected with the outer ring through a sliding unit and rotates along the annular groove in a sliding mode.
