Gas turbine Definition and 60 Threads

definition wise i got the difference between these two efficiencies. but in practice how does these two differ? i was referring to this book: Jet propulsion: a simple guide to the aerodynamics and thermodynamic design ... By N. A. Cumpsty he has mentioned this: "using polytropic...

Hi I am working on gas turbine design to investigate fatigue and creep failure and i want to design gas turbine blades for aircraft engine. I need to find out the dimention for CAd design if anyone help me that what should be the dimention of these blades and how many blades attached to...

Does anyone have a spreadsheet with formulas or a set of formulas that one can use to determine the turbine inlet temperature of a gas turbine knowing measured parameters like fuel flow, compressor discharge tempuratures, LHV of fuel.

Homework Statement I have been asked to calculate a range of values relating to a Gas Turbine engine, and while I have been able to find the majority of the values I am almost certain that the Thermal Efficiency value of 1.64% I have come up with is incorrect. This relies on Shaft power...

Hi all, I'm hoping that someone may be able to help! I'm doing a project which has involved me looking at the use of superalloys in Gas Turbine engines (i.e. Rolls Royce, GE etc). As part of that I am looking in particular at the use of Chromium within these engines, does anybody have any...

hi everyone: i have a question about gas turbines : i am working as instrumentation engineer( beggar ) at a power station .. we use gas turbine GE ( mark V) frame 9 . i got that alarm : exhaust thermocouple # 10 fail , drop number 123 if anybody working in such a field can help me in...

Again another homework question, all help greatly appreciated A gas turbine plant is fuelled by Methane,. After compresssion the air and fuel enter the combustion chamber at a temp of 600K and excess air is supplied in order to limit the temp of the combustion products to 1200K after steady...

Hello guys, I'm a second year BSc aerospace student in Holland, and I'm thinking about making a gas turbine engine. I hope to specialize in powerplants eventually. You people seem knowledgeable, so I thought I'd ask my question here. Anyway, bare with me a bit... I first thought about...

Is there any aero engine in the world without any rotating bodies like compressor-turbine? Other than ram jet or scramjet. Thers is a vague idea in my mind to go for an aero engine without rotating elements in it. I just wanted to confirm if it is there.

Why does the pressure in the burner of a gas turbine engine drop when you are increasing the internal energy of the air?
