Descripción del proyecto
Un sistema de control de flujo para turbinas de gas
Las turbinas son un sistema de propulsión común en las aeronaves modernas. En este sentido, es fundamental controlar el flujo interno de los motores para que las turbinas de gas funcionen de manera estable. La industria aeronáutica busca así aumentar su nivel de preparación tecnológica (TRL) en este ámbito. El proyecto financiado con fondos europeos ACONIT diseñará, producirá y demostrará accionadores de control de flujo que se integrarán en el compresor de un motor aeronáutico a escala completa. El proyecto estudiará en un primer momento las físicas de flujo de un sistema eficaz de control de la sobrecarga mediante la combinación de análisis numéricos y experimentales. Los resultados se emplearán para obtener información sobre fluidos en un sistema de control del flujo de gas y accionadores con un alto nivel de preparación tecnológica.
Objetivo
The objective of the ACONIT project is to design, manufacture and test actuators for flow control for an implantation in an aircraft engine. The actuators will fulfill aeronautics requirement in order to increase the Technology Readiness Level (TRL) in this domain. In particular, for the present proposal, one plans to focus on the extension of the stable operating range of axial compressor, allowing thus a reduction of the surge margin through postponing the stall onset. To do so, the first objective of the work is to improve the knowledge of the flow physics of an efficient flow control system by joint numerical and experimental analysis performed in a low speed, single stage axial compressor. The results of this analysis will be used to derive the fluidic specifications for a high TRL actuators and control system. These specifications will be the base for the design and manufacturing of amplified Piezo-electric actuator prototypes whose fluidic performance and operational performance in an environment with vibration and controlled level of temperature will be precisely evaluated before manufacturing final actuators that will be integrated in a full scale engine test facility. Their performance will be evaluated in terms of Surge Margin Improvement as well as in terms of energy balance between the induced consumption and the machine performance improvements.
The consortium grouped for carrying out this project is composed of a SME (CTEC), two academic institutions (Bundeswehr University Munich and ENSAM) and a Research Center (ONERA). It groups skills ranging from internal flow analysis in turbomachineries, to flow control or actuators design, manufacturing and characterisations.
