A Boeing 747 operated by Pan Am

Aviation includes the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships.

Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. (Full article...)

The air flow from the wing of this agricultural plane is made visible by a technique that uses colored smoke rising from the ground. The swirl at the wingtip traces the aircraft's wake vortex, which exerts a powerful influence on the flow field behind the plane.

Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Understanding the motion of air (often called a flow field) around an object enables the calculation of forces and moments acting on the object. Typical properties calculated for a flow field include velocity, pressure, density and temperature as a function of position and time. By defining a control volume around the flow field, equations for the conservation of mass, momentum, and energy can be defined and used to solve for the properties. The use of aerodynamics through mathematical analysis, empirical approximation and wind tunnel experimentation form the scientific basis for heavier-than-air flight.

External aerodynamics is the study of flow around solid objects of various shapes. Evaluating the lift and drag on an airplane, the shock waves that form in front of the nose of a rocket is an example of external aerodynamics. Internal aerodynamics is the study of flow through passages in solid objects. For instance, internal aerodynamics encompasses the study of the airflow through a jet engine.

The ratio of the problem's characteristic flow speed to the speed of sound comprises a second classification of aerodynamic problems. A problem is called subsonic if all the speeds in the problem are less than the speed of sound, transonic if speeds both below and above the speed of sound are present (normally when the characteristic speed is approximately the speed of sound), supersonic when the characteristic flow speed is greater than the speed of sound, and hypersonic when the flow speed is much greater than the speed of sound. Aerodynamicists disagree over the precise definition of hypersonic flow; minimum Mach numbers for hypersonic flow range from 3 to 12. Most aerodynamicists use numbers between 5 and 8.

The inverted Jenny (or Jenny Invert) is a United States postage stamp of 1918 in which the image of the Curtiss JN-4 airplane in the center of the design was accidentally printed upside-down; it is probably the most famous error in American philately. Only 100 of the inverts were ever found, making this error one of the most prized in all philately; an inverted Jenny was sold at a Robert A. Siegel auction in June 2005 for US$525,000.

Selected biography

Elizabeth 'Bessie' Coleman (January 26, 1892 – April 30, 1926), popularly known as "Queen Bess", was the first African American (male or female) to become an airplane pilot, and the first American of any race or gender to hold an international pilot license. Growing up in Chicago, she heard tales of the world from pilots who were returning home from World War I. They told stories about flying in the war, and Coleman started to fantasize about being a pilot. She could not gain admission to American flight schools because she was black and a woman. No black U.S. aviator would train her either. Coleman took French language class at the Berlitz school in Chicago, and then traveled to Paris on November 20, 1920. Coleman learned to fly in a Nieuport Type 82 biplane.

Selected Aircraft

Airbus A380
Airbus A380

The Airbus A380 is a double-deck, four-engined airliner manufactured by Airbus S.A.S. It first flew on 27 April 2005 from Toulouse–Blagnac Airport. Commercial flights began in late 2007 after months of testing, with the delivery of the first aircraft to launch customer Singapore Airlines. During much of its development phase, the aircraft was known as the Airbus A3XX, and the nickname Superjumbo has also become associated with the A380.

The A380 is double decked, with the upper deck extending along the entire length of the fuselage. This allows for a spacious cabin, with the A380 in standard three-class configuration to seat 555 people, up to maximum of 853 in full economy class configuration. Only one model of the A380 was available: The A380-800, the passenger model. It is the largest passenger airliner in the world superseding the Boeing 747. The other launch model, the A380-800F freighter, was canceled and did not join the ranks of the largest freight aircraft such as the Antonov An-225, An-124, and the C-5 Galaxy.
