Optimisation ot turbomachines through hybridisation of advanced manufacturing processes – TMACH_4.0

Submission summary

The TMACH_4.0 joint laboratory project is part of a global research project, linking AKIRA Technologies and ESTIA-Recherche, dedicated to "Innovative Aeronautical Propulsion" through three themes: Hybridisation and Electrification, Alternative Fuels, Materials and Processes. These themes respond to the roadmap on the challenges of tomorrow for a more efficient and less polluting aeronautical propulsion. TMACH_4.0 is part of the "Materials and Processes" theme and aims to develop a research activity on the use of composite materials and additive manufacturing in turbomachinery, based on the activities of ESTIA-Research's technology platforms: Compositadour and Addimadour. The research work carried out in the laboratory will focus on the following three areas:
- optimising the mechanical design of turbomachinery by adding degrees of freedom related to the implementation of materials and processes;
- reduction of the environmental impact of turbomachinery by introducing alternative materials and processes to reduce carbon emissions during the manufacturing and operating cycles;
- optimising design processes by developing innovative design/manufacturing methodologies combining numerical simulation and experimental validation of models (Digital Twinning).
TMACH_4.0 relies on the skills of AKIRA Technologies in the field of turbomachinery design and evaluation and ESTIA-Research in the field of design and optimisation of new manufacturing processes. The objective in 10 years is to propose new generation turbomachinery optimised for new uses and new energy sources. Two lines of research are envisaged.
The first axis concerns the optimisation of the performance of turbomachinery by developing a design methodology that combines numerical simulation and experimental validation of models, through the implementation of a common R&D methodology. The main originality concerns a close coupling between a complete modelling of the turbomachine and the experimental qualification of the elementary system to the sub-assembly, in order to build the equivalent of a numerical twin of the turbomachine throughout the innovation process, so as to estimate the gain in overall system performance.
The second axis focuses on challenging the usual manufacturing processes to open up a new avenue of innovation, by designing highly functional parts, with the aim of increasing the power density for small turbomachines. The question raised is to evaluate whether additive or composite manufacturing processes can be used to structure the material, in order to induce new laws of behaviour for parts in operation. The aim of the work will be to develop a hybrid manufacturing process coupling the implementation of composite processes and metallic processes by additive manufacturing. A functional material gradient approach could be envisaged, allowing structural optimisation layer by layer. A multi-material hybrid manufacturing approach will be targeted. The introduction of three-dimensional asymmetry coupled with local variations in material properties opens the way to the integration of new functionalities.
The first systems should be manufactured in T0+ 4 years, before being industrialised in T0+ 6 years. The objective is to reach a TRL7 level based on processes whose maturity varies between TRL3 and TRL6.
