Descripción del proyecto
Prueba de los módulos de salida del motor para los aeromotores de próxima generación
El desarrollo de estructuras de motores avanzadas, como los motores turbohélice de próxima generación y los motores de muy alto índice de derivación, es un paso importante para lograr una reducción del 75 % de las emisiones de CO2 para 2050. En estas estructuras de motores, los módulos de salida del motor (EEM, por sus siglas en inglés) tienen que soportar mayores temperaturas, demostrar menores pérdidas de presión y ser más ligeros sin comprometer el rendimiento. El objetivo del proyecto EATEEM, financiado con fondos europeos, es aumentar el nivel de madurez de los EEM. Los investigadores del proyecto probarán los EEM en una instalación singular de la Universidad Tecnológica Chalmers (Suecia). La instalación incluye una sección de pruebas abierta que permite la investigación de conjuntos de EEM formados por una estructura trasera de la turbina y una tobera de escape del núcleo.
Objetivo
A unique facility for experimental testing of engine exit modules (EEM) at engine-realistic flow conditions is currently available at Chalmers University of Technology and will be used to address this JTP action. The unique design of the facility includes an open test section which permits investigation of the complete EEM assemblies consisting of a turbine rear structure (TRS) and a core exhaust nozzle. The facility is equipped with a 1.5 stage shrouded low-pressure turbine (LPT) providing realistic inflow to the tested EEM. The parameters of the facility completely fulfil the requirements specified in the topic description. Thus, the LPT blade height, the flow Reynolds number range, the LPT flow coefficient, the LPT load coefficient, the LPT exit swirl angle range, the LPT hub-to-tip ratio and the purge flow are as specified. The instrumentation of the facility also completely fulfils the topic requirements. Multi-hole pressure probes are available upstream and downstream of the tested EEM. Both traversing systems are covering an entire 360-degree sector of the test section from hub to shroud. Furthermore, in practically all modern techniques of the flow and heat transfer diagnostics are available in the facility. This includes a complete set of equipment and software for PIV (particle image velocimetry) including high-speed stereo-PIV, tomographic-PIV, long-distance micro-PIV and endoscopic micro-PIV. Furthermore, equipment and software for surface oil-flow visualisation and oil-film interferometry, hot-wire and hot-film interferometry, pressure- and temperature-sensitive paints, digital image correlation (DIC), naphthalene sublimation, liquid-crystal thermography and IR-thermography are available as well. Personnel in the workgroup is highly skilled in using all these measurement techniques and has many years of experience in innovation turbomachinery research programs at national and European level.
