How does a high bypass jet engine work
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. WebMar 6, 2024 · Jet engines work fundamentally by drawing in air, lots of air, mixing it with fuel and expelling the resulting gases out the back at great speed. ... The biggest jetliners in service today have extremely high-bypass engines, where there is a high ratio between the air accelerated through the engine — bypassing the core — and the air going ...
