A safety protection system of an aircraft with multiple rotor wings comprises a receiver used for receiving ground remote control signals, an aircraft control circuit, a speed reducer, motors which are fixed at the ends of all rotary arms (1), and an aircraft power supply used for providing power for all above devices. The safety protection system of the aircraft with the multiple rotary wings is characterized in that a protection device control circuit, and a plurality of parachute popping-out devices (3) which are connected with the protection device control circuit and is controlled by the protection device control circuit to be triggered are arranged, after the parachute popping-out devices (3) are triggered, parachutes in the parachute popping-out devices are popped out, and protection to the multiple rotor wings is achieved. According to the safety protection system of the aircraft with the multiple rotor wings, the aircraft with the multiple rotor wings, which is in the flight process or in the low-altitude flight process, can be quickly and reliably protected, falling of the aircraft with the multiple rotor wings is prevented, and loss and personal injuries are avoided.
