Jet Propulsion: A Simple Guide to the Aerodynamic and ...
In this chapter we set about selecting the bypass ratio and with it the fan pressure
ratio. The overall pressure ratio and the temperature ratio 7o4/7o2 have been
selected in Chapters. Once we have selected the bypass ratio and fan pressure ...

Gas Turbine Performance
Increasing bypass ratio at fixed SOT and overall pressure ratio reduces the
optimum fan pressure ratio sharply. This is due to reduced core nozzle pressure
ratio and hence jet velocity, resulting from an increased LP turbine power
requirement ...
Philip Walsh, Paul Fletcher, 2008
These results were obtained using the equations just listed for ncL = 4 and
values 10 < nc < 30 and 6 < a < 15. As can be seen in this figure, increasing
either the bypass ratio or the compressor pressure ratio generally reduces the
specific fuel ...

Introduction to Aeronautics: A Design Perspective
The ratio of the bypass mass flow rate to the mass flow rate of the air flowing
through the core is called the bypass ratio. A turbofan is more efficient and
therefore has a lower TSFC because it accelerates more air (bypass air in
addition to core ...

Aviation and the Global Atmosphere: A Special Report of IPCC ...
The bypass ratio that is best for any given application is determined by a balance
between the increased drag and weight associated with the larger engine frontal
area needed for increased airflow and the increased propulsive efficiency ...
These are the compressor pressure ratio, the fan pressure ratio, and the bypass
ratio. The turbojet engine can be considered to be a special case of the turbofan
engine, which has a bypass ratio of zero. While the thermal efficiency of the ideal
...

Aerothermodynamics of Gas Turbine and Rocket Propulsion
1.3) are 5.8 bypass ratio, 32 compressor pressure ratio, and 1.4 fan pressure
ratio; for the mixed flow afterburning, F100 (Fig. 1.4), they are 0.78 bypass ratio,
25 compressor pressure ratio, and 3.0 fan pressure ratio, all at sea-level takeoff ...

Synthesis of Subsonic Airplane Design: An Introduction to ...
When the bypass ratio is increased at a given rpm, the fan diameter and tip
speed will also increase. In the case of many modern engines, part of the fan will
work at transonic speeds which, amongst other things, will cause an increase in
noise ...

Public hearings on noise abatement and control
Now, I spoke of high bypass ratio engine. I should define what I mean by bypass
ratio. The ratio of the airflow which is bypassed around the core engine to the
airflow that goes through the core engine is bypass ratio. The four noise sources
of ...
