Study of a turbofan engine

Abstract

The aim pursued by this project is to show the design of a complete turbofan. Because this design process is very complex and large groups of engineers for their development typically need the scope thereof in a final project is very limited. However, attempts to give an overview of what this design process and show the way forward from the work done. The next point that has been addressed is to explain the product itself: history, where comes, its operation, its component parts, the types of these engines and their general characteristics. It is very important for any design to have an art studio in this project is in the section of such engines. This serves to have a basis of what's on the market today and to mark us where our project has to go. In the section on components is made an explanation of the different configurations that exist of each component, of the problems that the engineer is to design them and solutions used to counteract these problems. Also discussed, but in the next chapter, the most commonly used materials for each component and the conditions that have to endure these materials. In the conceptual design is where begins to give shape to the turbofan. On the basis of specifications, provided by the study of the market and the requirements of the customer to which we want to direct our product, generates a mission and a study of the environment. Design of thermodynamic parameters is calculated from this point. The equations for the calculation of these parameters are found in annexes along with numerical results. Memory displays the results plotted together with the t-s diagrams. Once calculated design parameters you pass to the study of the configuration off-design. The results shown are dimensionless force, sfc, efficiency, the inlet temperature to the turbine (Tt4) and the relationship of bypass according to the altitude and the flight Mach number.
