Abstract

The present work deals with a detailed parametric thermodynamic analysis of all the possible configurtions of a turbofan engine (two and three spool with or without13; mixer and/ afterburner). The study focuses on design point performance and is of general nature rather than an application specific parametric study. The analysis13; has been carried out by selecting/developing models for various components of engine. A set of multi-dimensional carpet plots predicting the effect of dependent in13; terms of independent parameters has been presented considering transpiration coolingtechnique for turbine blades and the temperature effect on specific heat of13; air/gas. Besides giving the comparative design point performance for a class of turbofan engine, these results could also be useful in assessing the relative benefits13; of extending technology to new engine configurations.This study could be useful in selecting in general the cycle configuration for a particular need with its optimum13; operating parameters.
