Lift (force) — For other uses, see Lift. Boeing 747 8F landing A fluid flowing past the surface of a body exerts a surface force on it. Lift is the component of this force that is perpendicular to the … Wikipedia
Components of jet engines — Diagram of a typical gas turbine jet engine. Air is compressed by the fan blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which… … Wikipedia

Jet engine performance — This article describes how jet engine performance is estimated during the design phase. Similar techniques are used once the engine has been built and is being tested, except the performance of individual components, rather than being assumed, is … Wikipedia
Stokes stream function — In fluid dynamics, the Stokes stream function is used to describe the streamlines and flow velocity in a three dimensional incompressible flow with axisymmetry. A surface with a constant value of the Stokes stream function encloses a streamtube,… … Wikipedia
Streamlines, streaklines, and pathlines — Fluid flow is described in general by a vector field in three (for steady flows) or four (for non steady flows including time) dimensions. Pathlines, streamlines, and streaklines are field lines of different vector field descriptions of the flow … Wikipedia
Turbojet — Turbojets are the oldest kind of general purpose jet engines. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently during the late 1930s, although credit for the first turbojet is… … Wikipedia
Flownet — A flownet is a graphical representation of two dimensional steady state groundwater flow through aquifers. Construction of a flownet is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical.… … Wikipedia
Intake ramp — An intake ramp is a rectangular, plate like device within the air intake of a jet engine, designed to generate a shock wave to aid the inlet compression process at supersonic speeds. The ramp sits at an acute angle to deflect the intake air from… … Wikipedia
