Problems solved by technology

[0002] Traditional helicopters generally use total moment and period variable torque to control the flight of the helicopter; traditional helicopters have tails, and the function of the tail of a single-rotor helicopter is to overcome torque and control the heading, and traditional coaxial helicopters also have tails; The existence of the helicopter tail increases the size and quality of the aircraft, increases the mechanical complexity of the aircraft, and also increases the safety. Once the tail is damaged, it will endanger the safe flight of the aircraft; the traditional coaxial helicopter is to overcome the torque. , using an engine as the power, through mechanical transmission to complete the positive and negative rotation of the upper and lower rotors, the upper and lower rotors rotate at the same speed, and the steering is opposite, and the periodical variable torque is used to control the forward, backward, side flight and other actions of the coaxial helicopter, and the upper and lower rotors are used. The torque difference or the tail controls the heading to realize the steering operation of the aircraft

Embodiment Construction

[0033] Details and working conditions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 It is a schematic diagram of the appearance of a tailless vector coaxial helicopter design of the present invention. It adopts a double-motor upper and lower double-rotor structure, including an upper and lower rotor connected by paddle clips 3 and 5. The paddle clip 3 is fixed on the motor 2. The upper paddle clip 5 is connected on the lower motor 4 through the motor shaft, and the upper and lower rotors are coaxially reversed. The motor power system is fixed on the universal swash plate 9, and the swash plate 9 is installed on the fuselage without empennage.

[0035] The upper and lower motors are coaxial through the motor shaft 33. The upper rotor 6 is connected to the upper paddle clamp 5, and the lower rotor 7 is connected to the lower paddle clamp 3. The upper and lower rotors are forward and reverse, an...

Abstract

The invention discloses design for a tailless vector coaxial helicopter. A double-motor up-down double-rotor-wing structure is adopted, two motors are connected with an upper rotor wing and a lower rotor wing correspondingly, the rotating directions of the upper rotor wing and the lower rotor wing are opposite, torque is overcome by the identical rotation speed of the two motors, the rotation speed difference of the two motors is controlled, and steering operation is realized by torque imbalance brought by the rotation speed difference; vector control is adopted, a motor rotor wing power system is tilted through a tilting disc, the lift component of tilting of the rotor wings provides aircraft power, and flight of an aircraft in random directions is realized; the tailless vector coaxial helicopter comprises the upper rotor wing, the lower rotor wing, the upper motor, the lower motor, the vector tilting disc, pulling rods, a steering engine, a flight control system, an electronic speedcontroller, a power battery and a helicopter body; and the helicopter body is internally provided with a steering engine installing plate and a flight control system installing plate.
