Aircraft

The invention discloses an aircraft. The aircraft comprises an airframe and aero-engines mounted on the airframe. Each aero-engine comprises an engine, a propeller and a wind power supercharger. An outlet of each wind power supercharger communicates with an air inlet of the corresponding engine. An air inlet pressure sensor and a supercharging control valve are arranged on each air inlet pipe. Each supercharging control valve is connected with the corresponding air inlet pressure sensor. The mounting direction of the propeller faces the front portion of the airframe. Wind power generated during flying of the aircraft is utilized for driving the wind power superchargers, air is supercharged, that is, the air inlet pressure and the air increase amount of the aero-engines are increased, compressed air enters the engines through the air inlets of the engines, after the engines run, the propellers are driven to rotate, and propulsive force is generated; thus, by means of the aero-engines, the output efficiency of
