Pressure-driven multiaxial rotorcraft

The invention discloses a pressure-driven multiaxial rotorcraft. The pressure-driven multiaxial rotorcraft comprises a driving main frame, wherein an engine, a pressure pump and a multiaxial gyroscope are arranged on the driving main frame; the pressure pump is connected with the engine, and the periphery of the driving main frame is connected with at least three independent spiral assemblies; each spiral assembly comprises a support connected with the driving main frame, and pressure driving motors are arranged at the tail ends of the supports; the pressure driving motors are connected with propellers, and the pressure driving motors are connected with the pressure pump through a high-pressure guiding pipe and a low-pressure backflow pipe; and a pressure control valve is arranged on the high-pressure guiding pipe, and is connected with the multiaxial gyroscope. The engine drives the pressure pump to serve as main force source, and a hydraulic pump and an air pump can be used as the pressure pump, so that power output of liquid pressure and air pressure replaces existing electric power output, the runtime and the bearing capacity of the rotorcraft are greatly improved, and the pressure-driven multiaxial rotorcraft is suitable for various large or small unmanned aerial vehicles.
