Jet (mathematics) — In mathematics, the jet is an operation which takes a differentiable function f and produces a polynomial, the truncated Taylor polynomial of f , at each point of its domain. Although this is the definition of a jet, the theory of jets regards… … Wikipedia
Jet bundle — In differential geometry, the jet bundle is a certain construction which makes a new smooth fiber bundle out of a given smooth fiber bundle. It makes it possible to write differential equations on sections of a fiber bundle in an invariant… … Wikipedia
jet engine — an engine, as an aircraft engine, that produces forward motion by the rearward exhaust of a jet of fluid or heated air and gases. Also called jet, jet motor. [1940 45] * * * Any of a class of internal combustion engines that propel aircraft by… … Universalium
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
Jet engine compressors — As the name suggests, Jet engine compressors provide the compression part of the jet engine thermodynamic cycle. There are three basic categories of jet engine compressor:#Axial compressor#Centrifugal compressor#Mixed flow compressorAxial… … 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

Lift jet — A lift jet is a jet engine angled to provide an aircraft with aerostatic (i.e., not requiring the movement of air over an airfoil) lift instead of (or in addition to) thrust. On a fixed wing aircraft, lift jets may be installed as auxiliary… … Wikipedia
Contact geometry — Contact form redirects here. For a web email form, see Form (web)#Form to email scripts. The standard contact structure on R3. Each point in R3 has a plane associated to it by the contact structure, in this case as the kernel of the one form dz − … Wikipedia
Synthetic differential geometry — In mathematics, synthetic differential geometry is a reformulation of differential geometry in the language of topos theory. There are several insights that allow for such a reformulation. The first is that most of the analytic data for… … Wikipedia
Airbreathing jet engine — An airbreathing jet engine (or ducted jet engine) is a jet engine propelled by a jet of hot exhaust gases formed from air that is drawn into the engine via an inlet duct. All practical airbreathing jet engines are internal combustion engines that … Wikipedia
