WebApr 6, 2016 · Low-bypass turbofans don't use a lot of air for thrust; most of the air that transits the fan stage is routed into the engine, compressed, combusted, and exhausted like a standard turbojet. High-bypass turbofans route more air outside the combustion core, so the spinning fan generates most of the thrust (rather than the actual engine).

WebJun 7, 2015 · The fan (s) increases the pressure of the air that enters an engine. Some of this compressed air is diverted around the rest of the engine and is directed straight out of the engine. The bypass ratio is a measure of how much air bypasses the "jet" core (bypass air/core air). 2. The compressors WebDescription. A turbofan engine, sometimes referred to as a fanjet or bypass engine, is a jet engine variant which produces thrust using a combination of jet core efflux and bypass air which has been accelerated by a ducted fan that is driven by the jet core.

Since the bypass air is still passing through the engine inlet fan, it will have a slightly higher velocity compared to the outside. As a result, some thrust is also generated when bypass air exits the engine.

WebJul 7, 2015 · The bypass ratio is the proportion of the air which enters the engine inlet but bypasses the turbojet and exits at low speed, in comparison to the hot, high-speed jet coming from the engine core.
