Compressor Effects on Specific Fuel Consumption of Kerosene-fueled Civil Turbofans

Abstract

All gas turbine propulsion must have a compressor component that develops the pressure rise specified by the cycle. The main objective of the present study is to perform axial compressor pressure ratio effects on the specific fuel consumption of civil turbofans in both ideal and real cycles. At the beginning of this study, ideal and real cycle curves were drawn individually to explain the compressor pressure ratio behavior on the specific fuel consumption in excel and visual programming languages, respectively. At the second step, three dimensional response surfaces of the specific fuel consumption had been drawn according to the compressor pressure ratio. At the end of the study, real engines compressor data were marked on these curves and compared with results obtained in this paper.
