The invention discloses a coaxial contra-rotating jet propeller in the technical field of unmanned aerial vehicles. The coaxial contra-rotating jet propeller is characterized by comprising a thrust system, the thrust system comprises a front fairing, a front propeller arranged at the rear end of the front fairing, a rear propeller arranged at the rear end of the front propeller, a main bearing arranged at the rear end of the rear propeller and a reversing gear set connected with the main bearing. The front paddle shaft drives the front paddle and the driving gear to rotate, the driving gear drives the steering gear to rotate, the steering gear drives the driven gear to rotate, the driven gear drives the rear paddle shaft to rotate, and the rear paddle shaft drives the rear paddle to rotate. Through cooperative use of the single motor and the steering gear set, the two propellers rotating in the opposite directions rotate at the same time, the contra-rotating propellers can automatically balance the torque, the torque shown outwards is balanced, induced resistance can be reduced, and efficiency is improved.
