Abstract:

The Centre will undertake an innovative, application-defined and user-driven research program, using emergent and digital technologies for 3D printing of metallic materials and surface coatings as a sustainable and value-added manufacturing process across multiple industry sectors. They encompass extreme or hostile working high temperature, variable and dynamic stresses, oxidative and/or corrosive environments with primarily emphasis on space and aerospace propulsion systems, as well as for structural nuclear applications. The Centre will undertake both fundamental and applied research based on industry needs, generated from research topics of national interest, and grow the capability of the Centre, creating an institutional capacity aligned with international research trends based on exploitation of human-centered emergent and digital technologies dedicated to the needs of the society. To improve the efficiency, accuracy, and scalability of the research procedures, cutting-edge digital technologies such as simulation, artificial intelligence, and machine learning will be introduced as research methodologies. By the research agenda, the Centre activities exceed the conventional processes and applications addressing the challenges given by investigating the next generation of derivative alloys, multi-material manufacturing, bionic-inspired metamaterial structures, and novel surface coatings as to respond to the critical requirements of strategic industrial work environments.

Abstract:

In the context of the current requirements of increasing technological progress in the space field and reducing the mass of components used in space propulsion systems, the motivation of this project is to develop the additive manufacturing technology by laser powder bed fusion using Ti-6Al-4V alloy powders for the manufacturing of critical rotating components in an electropump, closed centrifugal impeller and inducer assembly with minimized mass and high performance. To overcome the technological limitations of conventional manufacturing methods, as well as to improve the operating performance of propulsion systems, the project exploits the advantages of additive manufacturing by coupling innovative techniques of generative design and technological optimization for the manufacture of rotating components, using lightweight "lattice" structures, under advantageous techno-economic conditions. To achieve the specific objectives of the project, fundamental and experimental research covering the entire technological process of additive manufacturing of pump components is included, i.e.: dimensioning and design based on the requirements, numerical simulations, topological optimisation, laboratory tests and analysis to evaluate the material/lattice structures, testing of preliminary models and validating final experimental models and validating final experimental models. By validating the experimental models in similarity conditions and comparing the results obtained with similar ex

Abstract:

The project aims to develop aircraft components: fan stator blades, as light as possible, with optimal functional and structural performances, which meet the operating regimes requirements, validated at a technological level TRL 4, and which integrates new structural architectures of composite materials advanced, manufactured using emerging additive manufacturing technologies, with low costs and manufacturing time, compared to traditional technologies (eg autoclave, VA-RTM). The development process of aviation components during the project implementation, follows a logical, staged procedure, starting from geometric design, defining structural architecture, providing 3D CAD model, perform thermo-mechanical characterization at laboratory level and numerical simulations, numerical and experimental results evaluation, in order to identify the optimal structural configuration, followed by the manufacturing of stator blades - Hardwar Prototype (s), testing the manufactured items in different relevant regimes, in correlation with the operation ones, assessment the results and performing the SWOT analysis. The Management and Dissemination activity has two major components: Project management aimed at allocating, monitoring and evaluating project resources, throughout its implementation, in direct correlation with the project objectives, and this task belongs to the project director, and respectively Dissemination of project results which is achieved by involving the entire project implementation team.
