All jet engines require high temperature gas for good efficiency, typically achieved by combusting hydrocarbon or hydrogen fuel. Combustion temperatures can be as high as 3500K (5841F) in rockets, far above the melting point of most materials, but normal airbreathing jet engines use rather lower temperatures.
A swan neck duct is a jet engine component, usually situated within the compression or turbine expansion system. [1] Many jet engines have a short annular passageway, linking two components, where there is a large change in mean radius, from front to rear. The shape of the resulting passageway is often similar to that of a swan or goose neck.
Notable engine with water fuel injection: BMW 801, Daimler-Benz DB 605, Junkers Jumo 213. When used in a turbine engine, the effects are similar, except that normally preventing detonation is not the primary goal. Water is normally injected either at the compressor inlet or in the diffuser just before the combustion chambers.
Diffuser (hair), a blowdryer attachment that diffuses heat as it dries the hair; Diffuser (heat), a cooking item that is placed above a heating element to separate the cooking utensil from the heat source; Diffuser (optics), a device that spreads out or scatters light; Diffuser (sewage), an aerating device for sewage and industrial waste water ...
A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket , water jet , and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet , turbofan ...
The PBS TJ150 is a small single-shaft turbojet engine consisting of a radial compressor, radial and axial diffuser, annular combustion chamber, axial turbine and a fixed outlet nozzle. The engine has a built-in starter-generator to start and supply power to the deck network, and a separate oil system.
There are numerous applications where a steady, uniform, isentropic flow is a good approximation to the flow in conduits. These include the flow through a jet engine, through the nozzle of a rocket, from a broken gas line, and past the blades of a turbine. m = Mach number V = velocity R = universal gas constant p = pressure k = specific heat ratio
Diffusers can be as a shape of round, rectangular, or can be as linear slot diffusers (LSDs). E.g., linear slot diffusers take the form of one or several long, narrow slots, mostly semi-concealed in a fixed or suspended ceiling with airfoils behind the slots directing the airflow in the desired direction.
