An aerodyne is a heavier-than-air aircraft which derives lift from motion. By contrast, an aerostat (such as a balloon) uses buoyancy to fly.
Types of aerodynesThere are several types of aerodynes, including: Fixed-wing aerodynesAll aerodynes that owe lift to their wings are fixed-wing aerodynes. The most common example is the aeroplane. Other examples include hang gliders and lifting bodies. (A convertiplane is a fixed-wing aircraft that achieves flight by the physical rotation of its engines.) Rotary-wing aerodynesHelicopters are the most widely known, but autogyros, gyrodynes, and tiltrotors are other types of rotary-wing aerodynes. OrnithoptersAn ornithopter is an aircraft that is neither a fixed-wing nor a rotary-wing craft. It obtains lift by the flapping of its wings in a bird-like fashion.
