How do jet engines work? - Aviation Stack Exchange
WebMay 20, 2024 · Jet fans are used to support the flow of air between the supply air and the air zones. They provide motion in regions that have low air speeds. How does a Jet fan … Imagine a fan (driven by an appropriately sized electric motor) operating within a pipe, which is connected to a propelling nozzle. It is fairly obvious, the higher the fan pressure ratio (fan discharge pressure/fan inlet pressure), the higher the jet velocity and the corresponding specific thrust. See more The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves See more Low-bypass turbofan A high-specific-thrust/low-bypass-ratio turbofan normally has a multi-stage fan behind inlet guide vanes, developing a relatively high pressure ratio and, thus, yielding a high (mixed or cold) exhaust velocity. The core … See more Cycle improvements Consider a mixed turbofan with a fixed bypass ratio and airflow. Increasing the overall pressure ratio of the compression system raises the combustor entry temperature. Therefore, at a fixed fuel flow there is an increase … See more The turbofan was invented to improve the fuel consumption of the turbojet. It would do this by increasing the mass and lowering the speed … See more Early turbojet engines were not very fuel-efficient because their overall pressure ratio and turbine inlet temperature were severely limited by the technology and materials available at the time. The first turbofan engine, which was only run on a test bed, … See more Turbofan engines come in a variety of engine configurations. For a given engine cycle (i.e., same airflow, bypass ratio, fan pressure ratio, overall pressure ratio and HP turbine rotor inlet temperature), the choice of turbofan configuration has little impact upon the … See more Aerodynamic modelling Aerodynamics is a mix of subsonic, transonic and supersonic airflow on a single fan/ See more WebJun 12, 2005 · Ducted fans/Electric Ducted Fans propel the aircraft on the reaction of the airflow leaving the outlet of the airframe. The impellor provides the action that transfers energy to the flow allowing semiscale flight of a jet model.
