WebAug 26, 2024 · How does a high bypass jet engine work? The compressor absorbs all the mechanical power produced by the turbine. In a bypass design extra turbines drive a ducted fan that accelerates air rearward from the front of the engine. In a high-bypass design, the ducted fan and nozzle produce most of the thrust. ... WebDec 20, 2014 · High-bypass turbofan engines do not create condensation trails. The ratio of air-to-exhaust is much too high to facilitate the formation of condensation because the majority of air expelled from the back of the engine is not combusted. It is passed through the "fan" and simply blown out the back without mixing with any fuel at all.

WebAug 10, 2024 · In simple terms, the higher the bypass ratio of an engine, the more efficient it will be, as the core is only responsible for generating a small part of the total engine thrust. It can even be said that the core's main function is to power the inlet fan in order to keep the bypass air flowing at capacity.
