Descripción del proyecto
Componentes ligeros para futuros generadores de alta potencia en aeronaves eléctricas
Los sistemas de propulsión híbrida-eléctrica o los sistemas totalmente eléctricos serán los encargados de que las nuevas aeronaves que la industria aeroespacial está desarrollando consigan reducir de forma considerable las emisiones de dióxido de carbono. La materialización exitosa de este tipo de aeronaves dependerá en gran medida del desarrollo de motores de propulsión con unas densidades de potencia un orden de magnitud superior a las actuales. El proyecto LIFT, financiado con fondos europeos, apoya este esfuerzo mediante diversas innovaciones aplicadas a la máquina de LIFT, como el aligeramiento de los componentes pasivos, los innovadores devanados de alta frecuencia y un enfoque específico de la gestión térmica mediante la refrigeración por pulverización de aceite. El objetivo es incorporar dichas innovaciones a las futuras arquitecturas de aviones híbridos-eléctricos, como los incluidos en el programa de grandes aeronaves de pasajeros de Clean Sky 2.
Objetivo
LIFT will deliver a beyond state of the art solution for lightweight non-active components for a megawatt range electrical machine proposed for Clean Sky 2 Large Passenger Aircraft IADP work package 1.6.1 as defined in the Topic Description JTI-CS2-2017-CfP07-01-4.
As stated in the Topic Description, the non-active parts of electrical machines contribute to 30-40% of the weight of the machine. LIFT proposes a number of solutions to reduce the mass and the weight of these non-active parts ranging from using composites or metal foams to corrugated structures that are all within the expertise of the University of Nottingham. In total, our preliminary workings illustrate that it is possible to deliver a mass and weight saving of at least 50% using a combination of technologies without significantly diminishing performance.
As a result of the research and innovation activities within the project, UNOTT foresees the generation of new knowledge in the following areas:
· An innovative MW-class generator with a record power density in excess of 25kW/kg will be developed
· Innovative thermal management systems will be developed exploiting the voids within lightweight materials
· A new family of lower-noise e-machines will be incepted, taking advantage of the voids within lightweight materials
· Development of novel mechanical models and advanced manufacturing methods for cylindrical lattice materials as required for e-machine designs, backed up by experimental testing
· The power density boundaries and limitations charts for future aerospace PM machines will be established for different speeds
