Modeling the Thrust and Specific Fuel Consumption for a Hypothetical Turbojet Engine

Abstract

The turbojet is the first kind of jet engine to produce the thrust. The air enters to the engine and comes to the combustion chamber and after mixing with fuel and combustion, it is released as a hot gas out of the nozzle. Turbojet engines are widely used in various industries, especially in military industries. Because of the importance of fuel consumption amount and its impact on the turbojet engine thrust in this article, the thrust force and specific fuel consumption for a hypothetical turbojet engine in ideal state according to flight speed and total pressure ratio has been analyzed. In order to analysis, EES software, which was used as a robust programming application in the field of heat and fluids sciences, has been gaining attention of the credible scientific communities in recent years. Finally, the obtained results have discussed and analyzed. The results of this paper can help in finding optimum engine operation conditions that give us the most thrust power from consumed fuel.
