The invention discloses a coaxial high-speed helicopter tail rotor propulsion transmission system structure which comprises an input shaft, an output shaft, a torque transmission structure, a clutch structure and a locking structure. The torque transmission structure comprises a torque transmission structure piston, a torque transmission structure piston outer sleeve and a torque transmission sleeve; the clutch structure comprises a clutch structure piston, a dual steel sheet, a friction plate and a clutch structure end cover; a driven end spline is arranged at the position, close to the clutch structure end cover, of the output shaft, the tail end of the torque transmission sleeve extends to the clutch structure end cover, and a key groove capable of being connected with the driven end spline is formed in the inner wall of the tail end of the torque transmission sleeve. An output shaft clamping table is arranged on the outer wall of the tail end of the output shaft; the locking structure comprises a locking structure sleeve and a locking structure piston; the high-speed helicopter can realize the conversion between the low-power state and the high-power state of the tail rotor when the high-speed helicopter flies at a high speed, and can realize the braking of the main rotor wing under a specific condition.
