Attitude transforming aircraft

The invention relates to an attitude transforming aircraft, which comprises an aircraft body, at least three connecting rods distributed around the body and positioned in one plane, rotors mounted at the outer end of each connecting rod, a controller installed inside the body, and a fixed wing disposed at the lower part of the body, with an angle formed between the chord line of the fixed wing and the plane of the connecting rods. When the aircraft flies forward, the rotating speed of the rotors can be adjusted to make the whole body tilt, and meanwhile, the fixed wing mounted underneath can provide an additional lifting force, thus improving aerodynamic efficiency, enhancing flying speed, reducing energy consumption, and increasing flight endurance and effective flying range. The aircraft of the invention has the high speed flying function of fixed wing airplanes, and can take off and land vertically, hover in the air, fly at any direction flexibly, and also has a simple structure.
