jet engine diagram

The compressor is made with many blades attached to a shaft. Ramjet turbopumps use ram air expanding through a turbine.

Combustor configurations include can, annular, and can-annular. Power available in the gas turbine exhaust is converted into a high speed propelling jet by the nozzle. Saved by Dave ray. Turbopumps are very commonly used with rockets, but ramjets and turbojets also have been known to use them. There are basically two forms of shock waves: A sharp-lipped version of the pitot intake, described above for subsonic applications, performs quite well at moderate supersonic flight speeds. Fuel is usually introduced by an atomized spray, the amount of which is controlled automatically depending on the rate of airflow. A complex air system is built into most turbine based jet engines, primarily to cool the turbine blades, vanes and discs. Take the possibility of increased altitude where there will be reduced air intake pressure. A pitot inlet is little more than a tube with an aerodynamic fairing around it. Rates for selected other engines are also given. Usually the flow is from the tank to the pump inlet and PRV, pumped to main oil filter or its bypass valve and oil cooler, then through some more filters to jets in the bearings. Radiusing of the lip prevents flow separation and compressor inlet distortion at low speeds during crosswind operation and take-off rotation. Major components of a turbojet including references to turbofans, turboprops and turboshafts: The various components named above have constraints on how they are put together to generate the most efficiency or performance. Fans are used for efficiency. An oblique shockwave will form at the start of the ramp. This can be kept at a sensible level either by increasing the number of compression stages (more weight/cost) or the mean blade speed (more blade/disc stress). The forces on the inside of the engine needed to create this jet give a strong thrust on the engine which pushes the craft forwards. A mixed exhaust is often employed nowadays. Depending on various conditions, such as flying through heavy rainfall, the igniter continues to provide sparks to prevent combustion from failing if the flame inside goes out. Deutsch: Schematischer Aufbau eines Strahltriebwerkes. 10:1), impeller stress considerations limit the pressure ratio that can be employed in high overall pressure ratio engine cycles. The CFM 56-5 jet engine (Airbus A320, A 340) Schematic model of the jet engine Bearings Bearings Intershaft bearing. This acts as a centrifugal compressor to pressurize the cooling air before it enters the blade. Conical (3-dimensional) and oblique shock waves (2D) are angled rearwards, like the bow wave on a ship or boat, and radiate from a flow disturbance such as a cone or a ramp. Some intakes are biconic; that is they feature two conical surfaces: the first cone is supplemented by a second, less oblique, conical surface, which generates an extra conical shockwave, radiating from the junction between the two cones.
