The invention relates to the technical field of unmanned plane out-of-control remediation, in particular to a remediation device adopting the biomimetic principle for reducing hazards caused by out-of-control aircraft and aims at achieving the technical purposes that when the aircraft needs forced landing, losses of people and things are reduced as much as possible, and meanwhile energy is replenished. According to the remediation device adopting the biomimetic principle for reducing the hazards caused by the out-of-control aircraft, a battery end and an electrostatic end are integrally arranged; a forced landing end is arranged to be rotated up and down automatically and connected with a three-dimensional balancing slide rail; a center shaft connection rod is arranged at the position close to the battery end and one third total length equivalent to the distance between the battery end and the electrostatic end in the horizontal direction and connected with the aircraft and the remediation device, the upper end of the center shaft connection rod is connected with the aircraft, and the lower end of the center shaft connection rod is connected with the three-dimensional balancing slide rail; the device can be detached from the bottom of the aircraft automatically or dismounted from or connected to the bottom of the aircraft through manual operation. The remediation device has the advantages that a biomimetic method is applied, the out-of-control condition is alleviated, and the forced landing end serves as a parachute and provides lift force for gliding; through bending or movement of nano-materials, heat is generated in the friction process, electricity is generated in the contact process, and electric energy and lift force are provided for flying.
