Jet stream — Jet streams are fast flowing, relatively narrow air currents found at the tropopause, the transition between the troposphere (where temperature decreases with height) and the stratosphere (where temperature increases with height), [United States… … Wikipedia
Jet damping — or Thrust damping is the effect of rocket exhaust removing energy from the transverse angular motion of a rocket. If a rocket has pitch or yaw motion then the exhaust must be accelerated laterally as it flows down the exhaust tube and nozzle.… … Wikipedia
Jet (particle physics) — A jet is a narrow cone of hadrons and other particles produced by the hadronization of a quark or gluon in a particle physics or heavy ion experiment. Because of QCD confinement, particles carrying a color charge, such as quarks, cannot exist in… … 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
Jet quenching — In ultra relativistic heavy ion collisions at center of mass energy of 5.5 TeV at the Large Hadron Collider (LHC), interactions between the high momentum Parton and the hot, dense medium produced in the collisions, are expected to lead to jet… … Wikipedia
Jet engine — For a general overview of aircraft engines, see Aircraft engine. A Pratt Whitney F100 turbofan engine for the … Wikipedia
Jet (fluid) — A jet is a coherent stream of fluid that is projected into a surrounding medium, usually from some kind of a nozzle or aperture. Jets can travel long distances with dissipating. In the Earths atmosphere there exist jet streams that travel… … Wikipedia
jet propulsion — the engine moves forward by reacting to the momentum of air of gaseous material being forced out of the back of the engine … Mechanics glossary
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
Stress-energy-momentum pseudotensor — In the theory of general relativity, a stress energy momentum pseudotensor, such as the Landau Lifshitz pseudotensor, is an extension of the non gravitational stress energy tensor which incorporates the energy momentum of gravity. It allows the… … Wikipedia
Propelling nozzle — A propelling nozzle is a component of a jet engine that is found at the tail of the engine that operates to form an exhaust jet and to maximise the use of the exhaust gas s energy throughout the engine so that the maximum overall thrust is… … Wikipedia
