The invention discloses a coaxial high-speed direct-driven helicopter which comprises a rack, a main rotor engine, a main rotor component, a main rotor drive shaft, a main rotor pitch regulating component, a tail rotor engine, a tail rotor impelling component, a tail rotor drive shaft, a tail rotor steering engine and a landing gear. According to the invention, rotors are directly driven to rotate by using the engines, so that the helicopter has the advantages of high efficiency, low noise, compact structure and reliable system. The main rotor engine is arranged right below the rotors, so that the center of gravity of the helicopter is concentrated, the rotational inertia is small, and the flexibility of maneuvering in the process of flight is improved. The main rotor pitch regulating component is used for regulating a lower rotor pitch, and carrying out linkage regulation on upper and lower rotor pitches, and also can carry out independent regulation on the upper rotor pitch, so that the difference of independent pitches of the upper and lower rotor pitches and the consistency of periodical pitches are realized, thereby improving the maneuvering characteristics such as rise and fall, rolling, pitching, yawing and inverted flight of the helicopter; and in a tail rotor impelling mode, the high-speed forward flight or backward flight of the helicopter can be realized.
