Why do jet engines have bypass airflow? Bypass usually refers to transferring gas power from a gas turbine to a bypass stream of air to reduce fuel consumption and jet noise. Alternatively, there may be a requirement for an afterburning engine where the sole requirement for bypass is to provide cooling air.
Why are bypass engines more efficient and what is the bypass air in a turbofan engine actually for? Because the fuel flow rate for the core is changed only a small amount by the addition of the fan, a turbofan generates more thrust for nearly the same amount of fuel used by the core. This means that a turbofan is very fuel efficient. In fact, high bypass ratio turbofans are nearly as fuel efficient as turboprops.
Where does bypass air go? The air moves through two parts of the engine. Some of the air is directed into the engine’s core, where the combustion will occur. The rest of the air, called “bypass air”, is moved around the outside of the engine core through a duct.
Why is higher bypass ratio better? As bypass ratio (BPR) increases the overall efficiency of the engine increase which is a primary factor that yields lower TSFC for the turbofan engine. Additionally this report shows that a high bypass ratio engine can produce a greater amount of thrust while consuming the same amount of fuel as a lower BPR engine.
