A Study on Turbofan engine for Knowing the Working Principle and to Recognize the Different parts.

Abstract

The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Most modern airliners use turbofan engines because of their high thrust and good fuel efficiency. Turbofans are the most widely used gas turbine engine for air transport aircraft. The turbofan is a compromise between the good operating efficiency and high thrust capability of a turboprop and the high speed ,high altitude capability of a turbojet. Our goal is to recognize the different part of a turbofan engine and to know working principles of turbofan engine .To achieve our goal, we divided our study in 12 stages. They are Introduction, Classification of Turbofan Engine, Turbofan Engine Components, Working principle of Turbofan Engine , Body Structure, Major Component, Gas Turbine Engine Fuel systems, Air Systems, Starting and Ignition, Power Augmentation Systems, Power Augmentation Systems, Result and Discussion and Conclusion .Before starting our thesis, we have studied different journals and thesis paper and different books and technical documents and we have collected information from it (reference) to determine the parts and working principle of Turbofan Engine. It will be better for us if we have an opportunity to open the total engine
