Aciturri participates in the development of the ValorH2 project "Research into new technologies, materials and processes associated with the hydrogen value chain", which includes, among other activities, the hydrogen generation by alkaline electrolysis technology, the compression of this gas at very high pressure and providing a high flow rate, innovative storage and transport solutions at very high pressure, and the use, on the one hand, of the hydrogen to refueling electric vehicles (fuel cells); and on the other hand, in a methanation process of CO2 recovered in the chemical industry (chemical reagent), with the aim of increasing efficiency, reducing the operative costs and minimizing the carbon footprint.

Aciturri leads the research of storage solutions for transport, distribution and service of hydrogen at high pressure. The storage solutions to be developed within the project are classified into type IV and type V tanks for mobile, stationary and intermodal transport solutions for hydrogen application for high pressures (700 bar) and large dimensions (5-11 m). It is estimated that progress at the end of the development will allow raising the gravimetric efficiency above 7%, by improving leakage, insulation and decreasing the H2 permeability of the liners.
This project is funded by the Center for Technological Development and Innovation (CDTI in spanish), under the Ministry of Science and Innovation, through the Missions 2022 call, which has “Next Generation EU” European funds within the Recovery and Resilience Mechanism.

The objective of the OVERLEAF project is to develop an innovative concept of liquid hydrogen tank for use in aviation without the need for high vacuum. Aciturri is leading this project which will reach TRL 3 level of technological maturity, being able to prove the validity of the concept of its proposed hydrogen tank. The need for this development is supported by the energy transition that the European Union wants to achieve through its "Hydrogen Roadmap Europe: A sustainable path for the European Energy Transition". The aeronautical sector sets the objective of reducing the effect of flights on global warming by between 50% and 90%. Hydrogen is the energy carrier that will make a significant contribution to meeting the targets.
The consortium, led by Aciturri Engineering, SLU and formed by AIMEN, CANOE, Universitat de Girona, Technische Universiteit Delft, Arkema France SA, ICSI, Norges Teknisk-Naturvitenskapelige Universitet and AIMPLAS, will address different challenges ranging from the description of the specifications of the tank and the development of new materials to the production of the prototype and testing to ensure its functionality.

OVERLEAF is an ambitious project supported by the experience of each of the participating companies, positioning the tank concept on which it is based as a potential candidate to be the hydrogen tank that will integrate the aircraft of the future.

This project is subsidized by the European Union through the 2021 call for Cluster 5 of the Horizon Europe Program.

Aciturri participates in the NEOTAIL project as one of the firms integrated in a consortium of companies. Aciturri is responsible for the work package for the development of a rudder for a medium-sized commercial aircraft. This will incorporate technological improvements that will allow higher production rates and lower costs, basing its construction on the use of thermoplastic resin materials reinforced with carbon fiber.

On the other hand, future aircraft will have to comply with new international regulations to reduce the environmental impact, both in their production and in their operating life, with the aim of minimizing emissions of polluting gases such as NOX and CO2. For this reason, the selection of thermoplastic arrays aims to contribute to the achievement of these objectives, since their easier recyclability allows components to be reused or removed from the production chain at the end of their useful life in a safer way.

This project will also address a change in the classic configuration of the rudders, seeking a greater integration of most of the elements of the torsion box in a single piece of CFRP with thermoplastic matrix. In this way, a multi-spar type caisson will be constructed, reinforcing the liners with stiffeners where necessary. This configuration eliminates transverse ribs, so the time and materials required for assembly are drastically reduced. For the installation of the invariant elements with respect to the most usual configuration (LERs, Skins, Fairings, Fittings...) improvements and optimizations of processes and tooling will be sought to reduce assembly times.

Within the NEOTAIL consortium, AIRBUS collaborates closely with Aciturri in the development of this work package, dedicated to control surfaces, as a possible end user. For the execution of the work, Aciturri is also supported by prestigious Technological Centers, such as FIDAMC in Getafe and CIDAUT in Boecillo.

This project has been subsidized by the CDTI and supported by the Ministry of Science and Innovation.

SLS Aero

The general goal of the project is to undertake the necessary research for the definitive and industrial application of additive manufacturing (AM) technology in the aeronautics industry, allowing the mass production of flight parts and tooling, which is to say, to increase the TRL of metallic additive manufacturing technology in the aeronautics market.

The following specific technical objectives have been proposed to achieve this:

- Determine the current capacity of AM technology using laser sintering to address the high-level requirements of the aeronautics industry.
- Increase knowledge of the influence of the principal variables of the laser sintering process on the final quality of parts (structural performance, metrology, etc.).
- Determine the possibility of maintaining the capacity for homogenization, repetition, and reuse of the material from AM technology, while still responding to the industry's requirements.
- Determine the current capacity of AM technology using post-processing to address the high-level requirements of the aeronautics industry.
- Increase knowledge of the influence of the principal variables of the post-processing processes on the final quality of parts.
- Validate findings by manufacturing tests of prototypes on a laboratory scale to demonstrate the capabilities and real needs of the complete technology (laser sintering + post-processing).
- Determine the most suitable process conditions that will make it possible to certify additive manufacturing processes for obtaining aeronautical components in the future.


Degree of homogeneity, repeatability and reuse of ALM technology materials applied to aeronautical sector requirements.

In order to study the repeatability of the process along with its quality, different experiments have been made that have allowed to analyze both mechanical properties and tolerance. Results indicate that the process is repeatable and that no significant differences are identified between the different working areas in the work platform of the SLS equipment.

Identification of the variables of operation of the laser sintering process more adequate to respond to the needs of the aeronautical sector.

We worked on the design, development and manufacture of test pieces, ad hoc parts and demonstrators. During the processes, we have evaluated the manufacturing strategies and machine parameters most appropriate to get the best results both from the dimensional and physical-mechanical point of view of each element. This experience has served to establish the most appropriate manufacturing methodologies to build right parts, guarantee repeatability of the process and its homogeneity.

Finishes and dimensional tolerance.

High requirements required in finishing and dimensional tolerance are characteristic of the manufacturing processes of the aeronautical sector. Inside this framework, analyzes, experiments and studies related to different technologies have been made, complementing the SLS, allowing to improve surface finish and achieve the required dimensional tolerance.

Identification of suitable materials for the aeronautical sector within the families of metal alloys previously identified as more appropriate.

Inside of aeronautics requirements, the metallic materials used are characterized by providing adequate mechanical properties with the smallest weight as possible. In this case, one of the materials most used is a titanium alloy (Ti6Al4V), which brings lightness at the same time as resistance. The studies made in the SLSAero project have focused on the analysis of this material and the results have been positive. Titanium alloys processed by SLS have high capacities for the aeronautical sector.

To progress in the scientific and technological development of robotics is one of the pillars of Industry 4.0 and constitutes one of the priority action axes marked by the European Commission to boost the competitiveness of the industrial sector in Europe.

The European project COROMA (Cognitively Enhaced Robot For Flexible Manufacturing of Metal and Composite Parts), an initiative coordinated by the technology centre IK4-IDEKO and in which Aciturri participates as final user of the advancements, is developed in this context. It seeks to develop a new concept of intelligent, modular and flexible industrial robots, with the capacity to execute multiple processes and to manufacture metallic and composites detail parts for sectors as demanding as aeronautics.

The robotic system will be able to perform drilling, trimming, deburring, polishing, sanding, non-destructive inspection and adaptive fixation. Using a simple interface, it will receive basic commands that will require minimal programming effort from the operator. In addition, it will move autonomously in the production plant, perceiving the manufacturing environment and locating the elements to be manipulated, even using the required tools for the processing of the pieces.

IMPACT - lighter protection systems for Defense through 3D printing

The IMPACT project is aimed at the "3D printing of new auxetic materials and structures for the improvement of passive protection systems for combatants" and is part of the R&D projects of interest for Defense included in the scope of the Program for Cooperation in Scientific Research and Development in Strategic Technologies (Coincident Program).
The fundamental concept of IMPACT is the design, development, fabrication and validation of reticular structures with auxetic properties. Auxetic structures and materials are those that have a negative Poisson's coefficient, which means that their behavior is the opposite of that usually expected when subjected to tensile/compression processes: when subjected to traction [compression] in the axial direction, an expansion [compression] is produced in the transverse direction. This characteristic makes the combination of these materials and structures ideal for protection systems and, as on other occasions, opens up a wide range of opportunities for their application in other sectors by combining lightness and strength in structures that until now had to be solid.
The scope of the project includes the validation of test specimens in different commercial materials, and also includes the specific development of a steel with ballistic quality, atomizable and processable through 3D printing technologies.
The project, sponsored and supervised by the General Directorate of Armament and Material of the Ministry of Defense of the Spanish Government, is led by Fundación Idonial and, together with Aciturri Additive Manufacturing SLU, ArcelorMittal Innovación Investigación e Inversión, SL and Fundación CIDETEC are participating in its development.
