The invention discloses an aircraft propeller composite material flexible propeller hub and a propeller applying the same, the flexible propeller hub comprises a first butterfly-shaped connecting piece, an outer propeller hub body and an inner supporting bone, the outer side wall of the first butterfly-shaped connecting piece is provided with a first butterfly-shaped ring groove, the inner supporting bone is arranged outside the first butterfly-shaped connecting piece in a sleeving mode, and the outer side wall of the first butterfly-shaped connecting piece is provided with a second butterfly-shaped ring groove; the inner side face of the inner supporting bone is matched with the first annular groove. The inner supporting bone and the first annular connecting piece are installed on the outer propeller hub body, a connecting hole is formed in the outer propeller hub body, the inner supporting bone is provided with an outer extending rod extending out of the connecting hole, and the outer extending rod extends outwards in the radial direction of the inner supporting bone. According to the composite material flexible propeller hub of the aircraft propeller and the propeller applying the composite material flexible propeller hub, the technical effects of being simple in structure, high in reliability, low in cost and long in service life are achieved, and the structure of the flexible propeller hub improves the centrifugal tensile strength of the propeller hub and reduces torsional resistance at the same time.
