The invention provides an unmanned aerial vehicle undercarriage distributed dual-redundancy hydraulic energy system, and belongs to the technical field of unmanned aerial vehicle braking systems.The system comprises a main energy module, an auxiliary energy module, an undercarriage folding, unfolding and limiting module and a braking execution module; the main energy module is connected with the auxiliary energy module, the undercarriage folding and unfolding and limiting module and the brake execution module. The auxiliary energy module is connected with the undercarriage folding and unfolding and limiting module and the brake execution module. When the hydraulic energy system works normally, the main energy module supplements pressure to the auxiliary energy module and supplies pressure to an undercarriage folding and unfolding actuating cylinder, a limiting lock actuating cylinder and a main brake of the undercarriage folding and unfolding and limiting module at the same time; when the main energy module breaks down, the auxiliary energy module supplies pressure to an undercarriage folding and unfolding actuating cylinder, a limiting lock actuating cylinder and a main brake of the undercarriage folding and unfolding and limiting module. The problem that an all-electric aircraft does not have a hydraulic source can be solved, and the reliability problem of a system is solved.
