The invention discloses a vector coaxial dual-rotor helicopter, and mainly solves the problems that the existing fixed-wing helicopter needs an airport runway, and the rotor wings of a common helicopter are bared so that the safety is not high and the driving difficulty is high, the vector coaxial dual-rotor helicopter comprises a cabin, a first-stage connecting frame is mounted on the cabin, a first-stage steering engine and a second-stage steering engine are mounted on the first-stage connecting frame, the upper portion of the first-stage connecting frame is movably connected with a universal connecting frame, the upper portion of the universal connecting frame is movably connected with a second-stage connecting frame, a rotorcraft frame and a top connecting pipe are installed on the upper portion of the second-stage connecting frame, and the first-stage connecting frame and the second-stage connecting frame are connected through a first connecting pipe and a second connecting pipe, and two brushless direct current motors are vertically mounted on the rotor frame in series. The vector coaxial double-rotor helicopter is simple in structure, high in rigidity, easy and convenient to operate and control, high in reliability, low in maintenance intensity and low in maintenance cost.
