Alexander Martin Lippisch (November 2, 1894 – February 11, 1976) was a German aeronautical engineer, a pioneer of aerodynamics who made important contributions to the understanding of tailless aircraft, delta wings and the ground effect, and also worked in the U.S. His most famous designs are the Messerschmitt Me 163 rocket-powered interceptorReitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, and the Dornier Aerodyne.
The alula, or bastard wing, (plural alulae) is a small projection on the anterior edge of the wing of modern birds and a few non-avian dinosaurs.
In fluid dynamics, angle of attack (AOA, or \alpha (Greek letter alpha)) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving.
Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth (or that of another planet).
Birds, also known as Aves, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.
The X-53 Active Aeroelastic Wing (AAW) development program is a completed American research project that was undertaken jointly by the Air Force Research Laboratory (AFRL), Boeing Phantom Works and NASA's Dryden Flight Research Center, where the technology was flight tested on a modified McDonnell Douglas F/A-18 Hornet.
In physics and fluid mechanics, a boundary layer is an important concept and refers to the layer of fluid in the immediate vicinity of a bounding surface where the effects of viscosity are significant.
In aeronautics, chord refers to the imaginary straight line joining the leading and trailing edges of an aerofoil.
In fluid dynamics, circulation is the line integral around a closed curve of the velocity field.
Cologne (Köln,, Kölle) is the largest city in the German federal state of North Rhine-Westphalia and the fourth most populated city in Germany (after Berlin, Hamburg, and Munich).
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
A droop or droop nose is a type of high-lift device found on the wings of some aircraft.
Electricity is the set of physical phenomena associated with the presence and motion of electric charge.
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing.
Elevons are aircraft control surfaces that combine the functions of the elevator (used for pitch control) and the aileron (used for roll control), hence the name.
The Fieseler Fi 156 Storch (English: Stork) was a small German liaison aircraft built by Fieseler before and during World War II.
A fighter aircraft is a military aircraft designed primarily for air-to-air combat against other aircraft, as opposed to bombers and attack aircraft, whose main mission is to attack ground targets.
A fixed-wing aircraft is an aircraft, such as an airplane or aeroplane (note the two different spellings), which is capable of flight using wings that generate lift caused by the vehicle's forward airspeed and the shape of the wings.
Flaps are a type of high-lift device used to increase the lift of an aircraft wing at a given airspeed.
A flaperon (a portmanteau of flap and aileron) on an aircraft's wing is a type of control surface that combines the functions of both flaps and ailerons.
Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude.
Germany (Deutschland), officially the Federal Republic of Germany (Bundesrepublik Deutschland), is a sovereign state in central-western Europe.
In mathematics, the gradient is a multi-variable generalization of the derivative.
Gustav Victor Lachmann (3 February 1896 – 30 May 1966) was a German aeronautical engineer who spent most of his professional life working for the British aircraft company Handley Page.
Handley Page Limited was founded by Frederick Handley Page (later Sir Frederick) in 1909 as the United Kingdom's first publicly traded aircraft manufacturing company.
The Handley Page HP.52 Hampden was a British twin-engine medium bomber of the Royal Air Force (RAF).
In aircraft design and aerospace engineering, a high-lift device is a component or mechanism on an aircraft's wing that increases the amount of lift produced by the wing.
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids.
Income is the consumption and savings opportunity gained by an entity within a specified timeframe, which is generally expressed in monetary terms.
Inertia is the resistance of any physical object to any change in its position and state of motion.
Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing.
The leading edge is the part of the wing that first contacts the air;Crane, Dale: Dictionary of Aeronautical Terms, third edition, page 305.
A leading edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities.
Ludwig Prandtl (4 February 1875 – 15 August 1953) was a German engineer.

In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.
Stealth technology also termed low observable technology (LO technology) is a sub-discipline of military tactics and passive electronic countermeasures, which cover a range of techniques used with personnel, aircraft, ships, submarines, missiles and satellites to make them less visible (ideally invisible) to radar, infrared, sonar and other detection methods.
