The invention belongs to the technical field of helicopter hydraulic systems, and particularly relates to a dual-redundancy helicopter hydraulic system and a control method. The first hydraulic subsystem is used for supplying pressure to the first main propeller steering engine cavity and the first tail propeller steering engine cavity so as to drive the main propeller steering engine and the tail propeller steering engine to work. The second hydraulic subsystem is used for supplying pressure to a main oar steering engine cavity II and a tail oar steering engine cavity II so as to drive a main oar steering engine and a tail oar steering engine to work; the first hydraulic subsystem comprises a hydraulic oil tank, a hydraulic pump, a first pressure sensor, a first pressure switch, a first main rudder stop valve, a first tail rudder stop valve, an oil return filter and a first multi-stage low oil level switch; the hydraulic pump is driven by the main speed reducer, sucks low-pressure oil from the hydraulic oil tank, converts the low-pressure oil into high-pressure oil, and supplies pressure to the main rotor steering engine and the tail rotor steering engine through the first main rotor stop valve and the first tail rotor stop valve respectively; the second hydraulic subsystem and the first hydraulic subsystem are the same in structure.
