any machine capable of flying by means of buoyancy or aerodynamic forces, such as a glider, helicopter, or aeroplane www.aerospaceweb.org/aircraft/index.shtml aircraft [′er‚kraft] (aerospace engineering) Any structure, machine, or contrivance, especially a vehicle, designed to be supported by the air, either by the dynamic action of the air upon the surfaces of the structure or object or by its own buoyancy. Also known as air vehicle. Aircraft Any vehicle which carries one or more persons and which navigates through the air. The two main classifications of aircraft are lighter-than-air and heavier-than-air. The term lighter-than-air is applied to all aircraft which sustain their weight by displacing an equal weight of air, for example, blimps and dirigibles. Heavier-than-air craft are supported by giving the surrounding air a momentum in the downward direction equal to the weight of the aircraft.
