Abstract:

The companies in the aerospace industry have developed a number of professional programs in order to simulate jet engines design and performance. These programs require a minimum previous knowledge in the tool and detailed information of the engines that are studied. Hence, an aerospace student does not have an appropriate way to learn how to use these professional programs. There is not a previous step where these requirements are not necessary. The eTURBO Library will permit the aerospace students to initiate themselves in a professional tool in a simplified version.

In our case, PROOSIS has been the program selected to carry out this project. It is a suitable option due to its capacity of modelling any kind of dynamic system by differential-algebraic equations (DAE) or ordinary-differential equations (ODE) and discrete events and it is an integrated visual environment that provides intuitive tools for making simulation easy. The eTURBO library (“educational-TURBO”) aims to be a previous stage to the TURBO library, which is a complex library where the users are able to simulate jet engine performance or design calculation with a high level of precision. In the eTURBO Library, a relevant quantity of simplifying hypothesis is considered and the mathematical formulation is adjusted to the mathematical model in the Aerospace Degree in the Technical University of Madrid. Consequently, eTURBO Library has the final purpose and the philosophy of teaching the students about PROOSIS and about jet engines performance and design.

The eTURBO Library presents a number of benefits for the degree and post-degree aerospace students. Firstly, the students will learn to work with a professional program for the simulation of the jet engines. Besides, it will serve as a complement to what have been studied in degree and post-degree subjects related to reactors. Furthermore, they will have the possibility of checking the problems proposed in class generating a model with the data variables in the statement and will be able to study different cases that corrected by themselves in order to deepen in problems that have not been possible to treat in class.
