Integrated supporting and damping device for unmanned helicopter and engine accessory of unmanned helicopter

The invention discloses an integrated supporting and damping device for an unmanned helicopter and an engine accessory of the unmanned helicopter, and belongs to the technical field of engine accessory supporting and damping devices. The problems that an existing engine accessory is independently fixed and supported, the supporting structure is complex, and part of non-key engine accessories cannot be subjected to vibration reduction are solved. The integrated supporting and damping device comprises a first arched beam, a first damper mounting frame and a first damper adapter plate. The first shock absorber mounting frame and the first shock absorber adapter plate are arranged at the two ends of the first arched beam respectively; a first steel wire rope shock absorber is arranged on the first shock absorber mounting frame, and a second steel wire rope shock absorber is arranged on the first shock absorber adapter plate; and the unmanned helicopter engine accessory is rigidly connected with the first arched b
