Aeronautics (from the ancient Greek words ὰήρ āēr, which means "air", and ναυτική nautikē which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere.
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft.
An aircraft is a machine that is able to fly by gaining support from the air.
An airliner is a type of aircraft for transporting passengers and air cargo.
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.
The Arado Ar 234 Blitz (English: lightning) was the world's first operational jet-powered bomber, built by the German Arado company in the closing stages of World War II.
The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.
The Blackburn Buccaneer was a British carrier-borne attack aircraft designed in the 1950s for the Royal Navy (RN).
The Boeing B-47 Stratojet (company Model 450) is an American long range, six-engine, turbojet-powered strategic bomber designed to fly at high subsonic speed and at high altitude to avoid enemy interceptor aircraft.
The deceleron, or split aileron, was developed in the late 1940s by Northrop originally for use on the F-89 Scorpion fighter aircraft.
The Deutsche Forschungsanstalt für Segelflug ("German Research Institute for Sailplane Flight" or "German Institute for Glider Research"), or DFS, was formed in 1933 to centralise all gliding activity in Germany, under the directorship of Professor Georgii.
Dive brakes or dive flaps are deployed to slow down an aircraft when in a dive.
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 drogue parachute is a parachute designed to be deployed from a rapidly moving object in order to slow the object, to provide control and stability, or as a pilot parachute to deploy a larger parachute.
Empirical evidence, also known as sensory experience, is the information received by means of the senses, particularly by observation and documentation of patterns and behavior through experimentation.
The English Electric Lightning is a supersonic fighter aircraft of the Cold War era.
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.
Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude.
In physics, a force is any interaction that, when unopposed, will change the motion of an object.
The fuselage (from the French fuselé "spindle-shaped") is an aircraft's main body section.
A glider is a heavier-than-air aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine.
Hans Jacobs (30 April 1907 - 24 October 1994) was a German sailplane designer and pioneer.
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids.
A jet engine is a type of reaction engine discharging a fast-moving jet that generates thrust by jet propulsion.
John Wiley & Sons, Inc., also referred to as Wiley, is a global publishing company that specializes in academic publishing.
A fluid flowing past the surface of a body exerts a force on it.
In aerodynamics, the lift-to-drag ratio, or L/D ratio, is the amount of lift generated by a wing or vehicle, divided by the aerodynamic drag it creates by moving through the air.
The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather tactical fighter aircraft designed by McDonnell Douglas (now Boeing) to gain and maintain air supremacy in all aspects of aerial combat.
Miles per hour (abbreviated mph, MPH or mi/h) is an imperial and United States customary unit of speed expressing the number of statute miles covered in one hour.
The Ministry of Supply (MoS) was a department of the UK Government formed in 1939 to co-ordinate the supply of equipment to all three British armed forces, headed by the Minister of Supply.
The National Aeronautics and Space Administration (NASA) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research.
The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research.
Northrop Corporation was a leading United States aircraft manufacturer from its formation in 1939 until its 1994 merger with Grumman to form Northrop Grumman.
The Northrop F-89 Scorpion was an American all-weather interceptor built during the 1950s, the first jet-powered aircraft designed as such from the outset to enter service.
The Northrop (later Northrop Grumman) B-2 Spirit, also known as the Stealth Bomber, is an American heavy penetration strategic bomber, featuring low observable stealth technology designed for penetrating dense anti-aircraft defenses; it is a flying wing design with a crew of two.
Parasitic drag is drag that results when an object is moved through a fluid medium.
Popular Science (also known as PopSci) is an American quarterly magazine carrying popular science content, which refers to articles for the general reader on science and technology subjects.
Scientific American (informally abbreviated SciAm) is an American popular science magazine.
The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by the U.S. National Aeronautics and Space Administration (NASA), as part of the Space Shuttle program.
The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium.
In aeronautics, a spoiler (sometimes called a lift spoiler or lift dumper) is a device intended to intentionally reduce the lift component of an airfoil in a controlled way.
