Anurag Anal

HELLO.....Farhat Asim

I am research in various article,pages and site to know about turboprop engine or jet engine to understanding the how T.S.F.C is varies with the height ,altitude and pressure for aero engine and find some technical calculation or graphs related to your topic.

I am giving you some PDF file for your topics please find and read them and relate with your projects..

Farhat Asim

@ Anal ..Dear I wanted to know about how for aero engines manufacturer computes these variations. Is it through some experimental technique or is it the analytical models.

U. Dreher

The basic data (at ground level - speed 0 and "normal pressure") can be obtained on some test stand.

As the dependencies on mach number and ambient pressure are known, the "missing" data is easily calculated.
