A passive braking system of an unmanned aerial vehicle comprises a normal braking system and an emergency braking system, the normal braking system and the emergency braking system can complete the braking function of a left airplane wheel and a right airplane wheel, and the normal braking system comprises a braking control box and two normal system electric control braking valves arranged left and right. The emergency brake system comprises a brake control box and two emergency system electric control brake valves arranged on the left and the right, the normal brake system and the emergency brake system share the brake control box, and the normal system electric control brake valve and the emergency system electric control brake valve located on the same side are jointly connected with a conversion valve through a pipeline. And the conversion valve is connected with the airplane wheel through a pipeline. According to the passive braking system of the unmanned aerial vehicle, conversion from a normal braking system to an emergency braking system can be autonomously achieved, and by arranging the emergency braking system, the fault that the normal braking system cannot build pressure, and consequently an airplane is not available for braking can be solved; and the problem of tire burst caused when a normal brake system cannot loosen the brake is solved.
