At Technological Institute of Aeronautics-ITA, the Flow Machines for Aerospace Applications course deals with turbopumps. It is offered to students of the second professional year in the undergraduate program. The objective of the course is to present enough information for the students to learn about machine preliminary design.
The theory involved in flow machines is multidisciplinary, so that the students must fully understand the principles of fluid mechanics, heat transfer, gas dynamics and thermodynamics, whose complete understanding is vital to start the design of such machine.
Lack of understanding the basic theory due to the problems like difficulty of associating the velocity triangles to blade angles, blade camber, incidence and deviation angles, makes the subject more complex than it really is. This problem is mitigated with hands-on activities during practical classes.
In this work, the syllabus of flow machines design course at ITA is presented, details of how the subjects are taught and the procedures used during the classes are reported, based on real life engineering project. After a period of theory and lab classes the students are requested to do a complete preliminary design of a turbomachine, using adequate numerical tools based on specs of a turbomachine. The instructor follows the class with discussions towards adjustments that could result in operational characteristics improvement. The project starts with meanline calculations to produce the base geometry and proceeds up to 3D CFD calculations to check the performance of the designed turbomachine and to subsidize design modifications. Experience exchanged with students are reported and commented aiming at course improvement.
