The DOZE project successfully concludes, driving multifunctional aerostructures for zero-emission aviation

 

The DOZE project (Advanced Manufacturing of Multifunctional Aerostructures for Zero-Emission Aircraft), led by AEROTECNIC and developed by a highly specialized industrial consortium comprising SMART MATERIALS 3D, NASIKA, Idaero, with the technological support of the AIMEN Technology Centre, has successfully come to an end, achieving the technical and innovation objectives defined at the outset of the project.

 

DOZE has addressed the development of lightweight and sustainable aerostructures through the combination of multimaterial composite materials (thermoset and thermoplastic), advanced out-of-autoclave manufacturing processes, and the integration of thermal management functionalities, contributing to progress toward zero-emission aviation.

From Idaero, the contribution has focused on the design of the DOZE demonstrator, a scaled section of an electric engine fairing based on a multimaterial composite structure with weight-saving and thermal management capabilities. This design was developed in close collaboration with the other consortium partners until a solution meeting the defined functional and manufacturing requirements was achieved.

In addition, Idaero carried out the study and definition of the advanced simulation strategy for the demonstrator, addressing heat transfer and thermomechanical analysis under representative flight conditions. The final solution was based on a sequential coupled thermomechanical finite element analysis using the Abaqus solver.

In parallel, Idaero developed an advanced digital tool to guide the design of functional materials and multimaterial aerostructures. This tool integrates numerical simulation models and a database containing the material characterization results generated by the consortium, enabling efficient generation of simulation inputs for the demonstrator and the evaluation of compliance with the defined thermomechanical requirements, thereby closing the complete design–simulation–validation loop.

 

From Idaero, we would like to thank all consortium members for their commitment, collaboration, and high technical level, which have been key factors in the success of the project and in jointly advancing toward cleaner, safer, and more efficient aviation.

 

DOZE is a project funded by the Centre for the Development of Industrial Technology (CDTI) and supported by the Ministry of Science and Innovation, under the Recovery, Transformation and Resilience Plan, financed with Next Generation EU funds.
