The invention relates to the technical field of unmanned helicopters, and provides an unmanned helicopter gravity center adjustment and energy absorption damping device which comprises a vibration absorber structure, a translation structure, a guide part and a driving mechanism. The vibration absorber structure comprises a vibration absorption connecting structure, airborne equipment and a plurality of elastic connecting pieces, the airborne equipment is installed on the vibration absorption connecting structure, the vibration absorption connecting structure is connected to the translation structure through the elastic connecting pieces, and the driving mechanism is used for driving the translation structure to move along the guide piece. A dynamic gravity center deploying system and a vibration absorption system are integrated into one system, the connecting rigidity of the system is adjusted to be matched with frequency doubling of a main rotor of the unmanned helicopter, and airborne large-mass equipment (an airborne storage battery) is used for constructing a local single resonance system for dynamic energy absorption and vibration reduction and the dynamic gravity center deploying system. Therefore, introduction of extra counterweight mass is avoided, the damping effect is achieved, the effective load weight and space of the helicopter are not occupied, and the range of the gravity center can be dynamically adjusted.
