When the air bag is dropped, the air bag bodies are vertically placed and positioned, and then the air in the cavity type auxiliary air bag is sucked out by the engine so as to generate enough buoyancy force. When the airplane is vertically lifted, an engine above the airplane body can be additionally used for downwards spraying air, and the left wing and the right wing are respectively lifted upwards and vertically to reduce the area of the ground runway; the aircraft can also take off or land on a ground runway in a running mode. The aircraft upper surface can be provided with a large-area thin-film solar panel which generates a large amount of electric power for driving the electric blades to generate thrust or lateral moving thrust; the unmanned aerial vehicle type is adopted, so that the robot can stay at high altitude for a long time; the airship can be expanded to be in an airship state and fly circularly in the air or hover in the air or in the air above a certain region; even when waiting to land in the sky above an airport in a city, the aircraft does not need to waste fuel and discharge polluted air when waiting to land in an air revolving circle like a conventional aircraft, simultaneously greatly improves the safety of the aircraft, and can suspend in the air or land safely at a low speed by using the buoyancy lift force of the airship in an emergency, thereby avoiding a serious disaster of machine damage and human death.
