Abstract
The objective of this thesis is to design and assemble a test rig able of both the assessment of on-ground performances and the analysis of the thermodynamic cycle of any given micro-turbojet engine. The latter requires the rig to be capable of measuring a set of physical quantities across the whole range of working conditions in order to asses component performances and efficiencies. Furthermore, this thesis will provide new equipment to the university and enable future works as it will be possible to perform studies with these type of engines or measure and quantify any modifications and improvements implemented in future theses. The present design, commission and assembly builds upon prior preliminary work on the expected thermodynamic cycle, analyzed in Torra's BSc thesis, and bellmouth design and simulation for the adequate conditioning of the input air flow, study performed by Quispe in his BSc thesis. The test rig is initially fitted for an evoJet B170neo engine, capable of 140 N of thrust, as many components have to be specifically adapted for the engine subject. The structure is made as modular as possible so that it can be re-used when switching engines. The design of those parts that have to be modified remains documented for future applications. The project also includes the design and implementation of an electronic system to condition the signals of the sensors, process the data and generate a meaningful database that can be used in post-processing applications for more complex studies. This system is also flexible enough to be used for various micro-turbojets, its design process and all programming files remain documented and available for future improvements. This document reports all the steps performed in order to achieve a functional and well-rounded test rig, however, it remains as a first version of this equipment with many improvements that can be added in future projects. Some ideas arose whilst working on this project but could not be put in action due to the length of the thesis and disparity of topics, these remain as future work. The resulting test rig was completely financed by the university and, therefore, remains at the disposition of the students to benefit of it through future demonstrations and practical work.
