Modeling the Thrust and Specific Fuel Consumption for a Hypothetical Turbofan Engine

Gholamreza Zarepour, Kiumars Khani Aminjan


Turbofan engine is a kind of jet engine in which a large part of the intake air without going into the combustion chamber that is exited from the terminal aperture. Turbofan engines have good efficiency in speed range of passenger aircraft and in terms of noise generation have also better functionality, for this reason in most of passenger aircraft this type of engine is used. Because of the importance of fuel consumption amount and its impact on the turbofan engine thrust, particularly in the commercial aircraft engine in this article the thrust force and specific fuel consumption for a hypothetical turbofan engine in ideal state according to flight speed and total pressure ratio has been analyzed. In order to analysis, EES software which was used as a robust programming application in the field of heat and fluids sciences and in recent years have been attention of the credible scientific communities. Finally, the obtained result has discussed and analyzed.
