The invention discloses a double-folding compact-layout coaxial dual-rotor aircraft, and belongs to the technical field of unmanned aerial vehicles. Upper and lower rotor wings in the power module are driven by upper and lower motors to rotate around a hollow main shaft to provide lift force for the aircraft, the upper and lower rotor wings can be folded downwards in a storage state to reduce the size, the lower rotor wings are connected with the variable-pitch mechanism, and the variable-pitch mechanism is driven by the control module to control the lower rotor wings to realize transverse and longitudinal control of the aircraft; the control module comprises a flight controller, a steering engine, a data chain and the like; a battery compartment of the energy module is flexibly mounted according to a flight mode; the load module is provided with various detection devices according to flight modes and task requirements; the undercarriage is located at the lowermost part of the aircraft body and can be folded upwards to reduce the storage size during storage. Switching of a standard mode, a long endurance mode and a maneuvering mode is achieved through flexible configuration of the upper battery bin, the lower battery bin and the load module, and the application range of an aircraft platform is expanded; by providing a double-folding modular layout design, the storage and transportation cost of the coaxial double-rotor aircraft is reduced.
