Aerospace engineering Aerospace engineering Aerodynamics is a branch of fluid dynamics concerned with the study of gas flows, first analysed by George Cayley in the 1800s. The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as velocity, pressure, density, and temperature, as a function of space and time. Understanding the flow pattern makes it possible to calculate or approximate the forces and moments acting on bodies in the flow. This mathematical analysis and empirical approximation form the scientific basis for heavier-than-air flight. The most aerodynamic shape is a raindrop. ...more on Wikipedia about "Aerodynamics"
Aeroelasticity is the science which studies the interaction among inertial, elastic and aerodynamic forces. ...more on Wikipedia about "Aeroelasticity"
Aerospace architecture is broadly defined to encompass architectural design of non-habitable and habitable structures and living and working environments in aerospace-related facilities, habitats, and vehicles. These environments include, but are not limited to: science platform aircraft and aircraft-deployable systems; space vehicles, space stations, habitats and lunar and planetary bases; and earth-based control, experiment, launch, logistics, payload, simulation and test facilities. Earth analogs to space applications may include Antarctic, desert, high altitude, underground, undersea environments and closed ecological systems. ...more on Wikipedia about "Aerospace architecture"
Aerospace engineering is the branch of engineering that concerns aircraft, spacecraft and related topics. It is often called aeronautical engineering, particularly when referring solely to aircraft, and astronautical engineering, when referring to spacecraft. ...more on Wikipedia about "Aerospace engineering"
An aerospace manufacturer is a company or individual involved in the various aspects of designing, building, testing, selling, and maintaining aircraft, aircraft parts, missiles, rockets, and/or spacecraft. ...more on Wikipedia about "Aerospace manufacturer"
Aircraft parts are components manufactured to be used on aircraft. Many companies around the world specialize in making aircraft parts. Because of strict regulations on aircraft maintenance in most countries, aircraft parts must often be certified by regulatory agencies, and for this reason are often considerably more expensive than comparable uncertified parts. ...more on Wikipedia about "Aircraft part"
In aerodynamics, the aspect ratio is an airplane's wing's span divided by its standard mean chord (SMC). It can be calculated more easily, however as span squared divided by wing area: ...more on Wikipedia about "Aspect ratio (wing)" www.shortopedia.com - Go in quickly.
Astronautics is the branch of engineering that deals with machines designed to work outside of Earth's atmosphere, whether manned or unmanned. In other words, it is the science and technology of space flight. ...more on Wikipedia about "Astronautics"
Bleed air in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burners. This compressed air can be used in many different ways, from de-icing to pressurising the cabin to pneumatic actuators. However, bleed air is quite hot and if being used in the cabin or other low temperature areas it must be cooled, even refrigerated. Bleed air is valuable in an aircraft for two properties: its high temperature and its high pressure. ...more on Wikipedia about "Bleed air"
Cabin pressurization is required when an aircraft reaches high altitudes. This is because, as the plane gains altitude, the atmospheric pressure decreases, and the amount of oxygen becomes insufficient for humans to breathe properly. The maximum operational height of a plane includes considerations for cabin pressure. ...more on Wikipedia about "Cabin pressurization"
In reference to aircraft, chord refers to the distance between the front and back of a wing, measured in the direction of the normal airflow. These front and back points are referred to as the leading edge and trailing edge. ...more on Wikipedia about "Chord (aircraft)"

The cruciform tail is an aircraft empennage configuration that, viewed edge-on, looks much like a cross. In this arrangement, the horizontal stabilizer intersects the vertical tail somewhere near the middle, and above the top of the fuselage. Often this arrangement is chosen to keep the tail out of the engines' slipstream or to avoid complex interference drag. ...more on Wikipedia about "Cruciform tail" Stay cool with shortopedia.

Damage tolerance is the ability to withstand damage. The term is most often used in aerospace engineering to indicate the following characteristics of a component or material: ...more on Wikipedia about "Damage tolerance"
The United States Air Force Digital Datcom is a computerized version of the USAF Data Compendium, a large collection of information used by aerospace engineers to predict airplane stability and handling properties. Digital Datcom takes an input file containing a geometric description of an airplane, and outputs its corresponding dimensionless stability derivatives. These numbers can be used to calculate meaningful aspects of flight dynamics. ...more on Wikipedia about "Digital Datcom"
The drag coefficient (Cd or Cx) is a number that describes a characteristic amount of aerodynamic drag caused by fluid flow, used in the drag equation. Two objects of the same frontal area moving at the same speed through a fluid will experience a drag force proportional to their Cd numbers. Coefficients for rough unstreamlined objects can be 1 or more, for smooth object much less. ...more on Wikipedia about "Drag coefficient"
A dripstick is a tube installed vertically in the bottoms of fuel tanks of many large aircraft, used to check fuel levels. To read a dripstick, it is withdrawn from the lower surface of the wing. When the top of the dripstick is withdrawn below the level of the fuel, fuel enters the dripstick and drips through a hole in the cap. Graduations on the dripstick indicate the level of the fuel in the tank. ...more on Wikipedia about "Dripstick"
Energy Maneuverability theory is a model of aircraft performance. It was promulgated by Col. John Boyd, and is useful in describing an aircraft's ability to acquire and preserve kinetic energy. ...more on Wikipedia about "Energy-Maneuverability theory"
The Environmental Control System of an airplane provides air supply, thermal control and pressurization for the passengers and crew. Avionics cooling, smoke detection, and fire suppression are also commonly considered part of the Environmental Control System. ...more on Wikipedia about "Environmental Control System"
Flight dynamics is the study of orientation of air and space vehicles and how to control the critical flight parameters, typically named pitch, roll and yaw. ...more on Wikipedia about "Flight dynamics"
A floatstick is a device to measure fuel levels in modern large aircraft. It made up of two tubes, one enclosed within the other, around which is a ring-shaped float that contains a magnet. There is also a magnet attached to the top of the floatstick. The floatstick is withdrawn from the bottom of the wing until the magnets stick, indicating the level of the fuel. ...more on Wikipedia about "Floatstick"
The Helicon Double Layer Thruster is a prototype spacecraft propulsion engine. It was created by Australian scientist Dr. Christine Charles, based on a technology invented by Professor Rod Boswell, both of the Australian National University. ...more on Wikipedia about "Helicon Double Layer Thruster"
In aerodynamics, hypersonic speeds are speeds that are highly supersonic. In the 1970s the term generally came to refer to speeds of Mach 5 and above. The hypersonic regime is a subset of the supersonic regime. ...more on Wikipedia about "Hypersonic"
