Abstract

Overall efficiency is an important design parameter of the engine in preliminary design and defined as the ratio of aircraft thrust power to the rate of thermal energy released in the engine. In this paper, effects of the fan pressure ratio and the bypass ratio on engine overall efficiency were investigated for afterburning and separate flow turbofans. With this purpose, fan pressure ratio⎯bypass ratio⎯overall efficiency three dimensional graphs were developed and then computer experiment results were evaluated for three different flight Mach number.

Özet

Toplam verim, itki sistemi ön tasarımda önemli bir parametredir ve motordan elde edilen itki gücünün motora verilen ısıl enerjiye oranı olarak tanımlanır. Bu çalışmada, ayrık akışlı ve ardyanmalı turbofan motorlarda fan basınç oranı ve bypass oranı değişkenlerinin motorun toplam verimi üzerindeki etkileri araştırılmıştır. Bu amaçla motora ait fan basınç oranı-bypass oranı-toplam verim değişimlerini üç boyutlu gösteren yüzey grafikleri oluşturulmuş ve üç farklı uçuş hızı için bilgisayar deneyleri yapılarak elde edilen sonuçlar yorumlanmıştır.
