The gas turbine was one of the most important technological developments of the early 20th century, and it has had a significant impact on our lives. Although some researchers have worked on predicting the performance of three-shaft gas turbines, the effects of the deteriorated components on other primary components and of the physical faults on the component measurement parameters when considering the variable inlet guide valve scheduling and secondary air system for three-shaft gas turbine engines have remained unexplored. In this paper, design point and off-design performance models for a three-shaft gas turbine were developed and validated using the GasTurb 13 commercial software. Since the input data were limited, some engineering judgment and optimization processes were applied. Later, the developed models were validated using the engine manufacturer’s data. Right after the validation, using the component health parameters, the physical faults were implanted into the non-linear steady-state model to investigate the performance of the gas turbine during deterioration conditions. The effects of common faults, namely fouling and erosion in primary components of the case study engine, were simulated during full-load operation. The fault simulation results demonstrated that as the severity of the fault increases, the component performance parameters and measurement parameters deviated linearly from the clean state. Furthermore, the sensitivity of the measurement parameters to the fault location and type were discussed, and as a result they can be used to determine the location and kind of fault during the development of a diagnosis model.

“…Además, los alumnos se sienten más atraídos por la actividad al romper la barrera que representan los complejos y tediosos cálculos manuales. A partir de una serie de condiciones de contorno, que dependen principalmente de la aplicación seleccionada, se puede analizar un gran número de arquitecturas de motor en un período de tiempo reducido (Gao, 2011). Como resultado, se puede proporcionar una primera definición de parámetros clave en la tecnología estudiada, como la relación de compresión global, la tasa de derivación o la temperatura en la entrada de la turbina (Klein, 2015), de forma justificada en base al análisis del ciclo.…”

En este trabajo se describe una metodología enfocada a mejorar la comprensión del ciclo termodinámico de motores a reacción mediante la combinación de un estudio del caso y un entorno de simulación. La metodología se desarrolla para estudiantes de la asignatura de Propulsión del Grado en Ingeniería Aeroespacial. En particular, se pide a los estudiantes analizar con detalle el impacto de las dos principales condiciones de contorno que afectan a las prestaciones del motor: altitud y velocidad de vuelo (o Mach). El estudio del caso se hace en grupos de cinco estudiantes, y ha mostrado resultados positivos tanto en rendimiento académico cmo en cuanto a la implicación del alumnado en general. No obstante se han identificado algunos aspectos a mejorar. Por un lado, el aumento del número la diversidad del alumnado ha desafiado la organización del trabajo, mostrando peores resultados en grupos con estudiantes que tenían un bagaje diferente al habitual. Por otro lado, hay una aparente desconexión entre la metodología usada y la organización de otras asignaturas de la misma área de conocimiento del grado. Se propone una actualización de la metodología para mejorar ambos aspectos.

“…At the same time, the students feel more attracted by the activity since the stage of analysis becomes easily accessible once the barrier represented by complex and tedious calculations is broken. From a series of boundary conditions mainly depending on the selected application, a wide number of engine architectures can be screened in a reduced amount of time [10]. As a result, the first definition of key parameters in the studied technology, such as the overall pressure ratio, the bypass ratio, or the temperature at the turbine inlet can be provided [18] and robustly justified based on cycle analysis.…”

In the current paper, a methodology combining a case study with a computational tool for aerospace engineering students is presented and discussed.The aim of this methodology is to improve the understanding of jet engine's operation through their thermodynamic cycle analysis, particularly focused on the effects of the main boundary conditions for an aircraft engine: altitude and flight velocity (or Mach). Additionally, the organization of the methodology as a case study performed in groups helps to facilitate student engagement, as well as the development of soft skills, such as teamwork ability. The experience of this methodology over the last 5 years shows that the activity is generally well perceived by the students, and also that there is a correlation between the engagement in this activity and the overall results achieved in the subject, confirming that the methodology helps to improve students' comprehension of the concepts behind engine performance. However, a few points of improvement for the near future are identified.
