The invention discloses a triphibious coaxial four-rotor aircraft. Four turn-back supporting arms are arranged on an airframe and comprise airframe supporting arm ends, rotor support arms, turn-back sections and turn-back driving mechanisms. The airframe supporting arm ends are connected with the rotor support arms through the turn-back sections. The turn-back driving mechanisms are used for driving the airframe supporting arm ends and the rotor support arms to rotate by forming 90-degree angles with the turn-back sections. Driving devices are arranged at the ends of the turn-back supporting arms and comprise fixed seats. Land motors and aerial motors are arranged in the fixed seats. Coaxial land inner shafts and aerial outer shafts are arranged on the fixed seats. Wheel axles and light tyres are arranged at the tops of the land inner shafts. Three-blade rotors are arranged at the tops of the aerial outer shafts. The output of the land motors is connected with the land inner shafts. The output of the aerial motors is connected with the aerial outer shafts. Flexible triphibious transformation is achieved. Energy saving is achieved by changing motion states. The application of the four-rotor aircraft is expanded. The speed of sailing on water is improved. A control system is simplified. Cost is lowered.
