The invention relates to a coaxial double-rotor ducted aircraft, which solves the problems of poor high-speed flight capability and complex structure of ordinary rotorcraft. The upper bracket and the lower bracket are connected by a support plate to form a whole machine bracket, and have an airfoil duct body Around the support, the landing gear is installed on the periphery of the lower support, the motor power supply is installed on the upper part of the upper support, and the coaxial motor composed of two motors of the same type is installed in the center of the upper support. The propeller is fixed on the propeller shaft of the motor. The two propellers are of the same type. The direction of rotation of the propellers is opposite, the lower bracket is equipped with the lower central body, the upper layer of the lower central body is equipped with the attitude reference system, the middle layer is equipped with the power supply of the flight control system, the lower layer is equipped with the flight control board, and the inner circumference of the lower bracket is equidistantly installed. The steering gear is connected to the control panel through the control panel linkage. The invention has hovering, low-speed and high-speed flight capabilities, can take off and land vertically, has strong adaptability, good concealment, compact structure and wide application range.
