WebSep 17, 2024 · The process by which this happens is sometimes bluntly explained by the concept of ‘suck, squeeze, bang, blow.’. Air is sucked into the engine from the front using the big fan visible when looking at a plane straight on. That air is then compressed in the next stage of the engine – this is the ‘squeeze’ part. A second fan increases ... 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

High induction jet fan systems generate a relatively high discharge velocity, causing the discharge air to collide with the air in front of the jet fan to thrust it forward. At the same time, this collision creates friction that draws the surrounding air to create an induction effect that moves it in the airflow direction.
