Flashcards: Aerodynamics

Shock diamonds (also known as Mach diamonds, Mach disks, Mach rings, donut tails or thrust diamonds) are a formation of standing wave patterns that appear in the supersonic exhaust plume of an aerospace propulsion system, such as a supersonic jet engine, rocket, ramjet, or scramjet, when it is operated in an atmosphere.

In fluid dynamics, laminar flow (or streamline flow) occurs when a fluid flows in parallel layers, with no disruption between the layers.

In physics, the Navier–Stokes equations /nævˈjeɪ stoʊks/, named after Claude-Louis Navier and George Gabriel Stokes, describe the motion of viscous fluid substances.

The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium.

Standard conditions for temperature and pressure are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data.

Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1).

In physics and fluid mechanics, a boundary layer is the layer of fluid in the immediate vicinity of a bounding surface where the effects of viscosity are significant.

In fluid dynamics, a Kármán vortex street (or a von Kármán vortex sheet) is a repeating pattern of swirling vortices caused by the unsteady separation of flow of a fluid around blunt bodies.

Wingtip devices are intended to improve the efficiency of fixed-wing aircraft.

An airfoil (in American English) or aerofoil (in British English) is the shape of a wing, blade (of a propeller, rotor, or turbine), or sail (as seen in cross-section).

In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord.

In physics, specifically electromagnetism, the Biot–Savart law (/ˈbiːoʊ səˈvɑːr/ or /ˈbjoʊ səˈvɑːr/) is an equation describing the magnetic field generated by an electric current.

Nozzle extension — nozzle expander of reaction/rocket engine.

Codex on the Flight of Birds is a relatively short codex of circa 1505 by Leonardo da Vinci.

An impeller (also written as impellor or impellar) is a rotor used to increase (or decrease in case of turbines) the pressure and flow of a fluid.

A boiling liquid expanding vapor explosion (BLEVE, /ˈblɛviː/ BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid above its boiling point.

Flight dynamics is the science of air vehicle orientation and control in three dimensions.

For the pyrotechnic initiator, see Shock tube detonator The shock tube is an instrument used to replicate and direct blast waves at a sensor or a model in order to simulate actual explosions and their effects, usually on a smaller scale.

The aircraft design process is the engineering design process by which aircraft are designed.

The intent of this article is to highlight the important points of the derivation of the Navier–Stokes equations as well as the application and formulation for different families of fluids.

Asymmetry of lift describes an aspect of the nature of aerodynamic lift generation along the length of an individual rotor blade of a helicopter.

A drag-reducing aerospike is a device (see Nose cone design) used to reduce the forebody pressure aerodynamic drag of blunt bodies at supersonic speeds.

In physics and engineering, Davenport chained rotations are three chained intrinsic rotations about body-fixed specific axes.
