OVERLEAF's goal is to create a 95 kg liquid hydrogen tank by combining the development of new materials such as composites and insulation.

In the framework of the Horizon Europe program, in the call aimed at promoting clean and competitive solutions for all transportation modalities, Aciturri is leading the OVERLEAF project since May 2022 with the main objective of creating a 95 kg liquid hydrogen tank by combining the development of new materials such as composites and insulation.

The OVERLEAF project involves 10 participants from 6 different countries of the European Union, carrying out activities among leading companies in their sector, together with technology centers and universities.

Aciturri, with a grant of more than 1.13 M€, not only leads the project, but also takes on the design of the tank, studying both weight reduction and integration into the aircraft structure. The objective is to achieve a higher gravimetric index than existing solutions, around 50%. These advances will be made by integrating the developments carried out by the other partners under Aciturri's knowledge of the requirements of the aeronautical sector.


Access to space by means of a pressurized capsule that rises to the stratosphere.

HALO is a Spanish space tourism project that pretends to access space by means of a pressurized capsule that rises to the stratosphere (45 km.) using helium balloons.

Aciturri participates in the project by manufacturing and integrating the capsule. During the second half of 2022, the development and innovation teams built the capsule for the first unmanned flight to demonstrate the feasibility of the concept. This first structure was largely made of carbon fiber using infusion processes. The use of this technology is not common in aeronautics, but there is a general tendency to increase its use in aircraft due to its competitive advantages, such as low cost and speed of manufacture, which make it ideal for prototypes and innovation demonstrators. These are the first parts of these dimensions to be produced by Aciturri and the first to have a use beyond laboratory research.

Once the manufacturing and assembly was completed, the different parts were disassembled and packed so that they could be sent to India for the first flight. A team from Aciturri traveled to Hyderabad (India) to continue the reassembly and to support the flight, which finally took place successfully in the early hours of 7 December. The capsule reached an altitude of 39 km and collected data for three hours, recording parameters and images that will be used to prepare the next launches.


To develop a thermoplastic spoiler solution, researching new manufacturing technologies.

Within the framework of the 2022 call of the Aeronautical Technology Program (PTA), Aciturri Engineering is leading the project "Innovative Aerostructures oriented to Emission Reduction-AIRE", in which the companies Airbus Defence & Space (ADS), Aeronautics, Engineering, Renewable Energies and Safety (AERYS), Titania Ensayos y Proyectos Industriales (TITANIA), M.Torres Innovación y Desarrollo (MTORRES), and Principia Ingenieros Consultores (PRINCIPIA) are participating.

Within this project, Aciturri seeks to develop a thermoplastic aileron solution, investigating new manufacturing technologies with thermoplastic materials that complement other ongoing research, as well as the research and development of new integrated solutions of different components with thermoset materials, and the challenges presented by high thickness sandwich components and aggressive ramps.


Design of new helicopter aerostructures that meet the requirements of increased energy efficiency and decarbonization.

Aciturri is involved in the "Disruptive Helicopter of the Future - LIDER" project, within the scope of the 2022 call of the Aeronautical Technology Program (PTA). The project, led by Airbus Helicopters, proposes the Design of new helicopter aerostructures that meet the requirements of increased energy efficiency and decarbonization, aerodynamic improvements, environmental impact and circular economy, without detriment to flight and operational capabilities.

Aciturri will design, develop and manufacture the belly fairing and the ALDI train traps (ALa DIsruptiva) using out-of-autoclave cured prepreg materials. It will also design, develop and manufacture the CES fairing (Efficient and Sustainable Fairing) using out-of-autoclave curing infusion and withstand the high temperatures generated by the engines. With these developments, Aciturri continues its research in out-of-autoclave (OoA) technologies.


ValorH2 studies the green hydrogen value chain stages: generation, compression, storage, transportation and use.

In December 2022, CDTI, within the Missions 2022 call, approved the ValorH2 project, which will study the different stages of the hydrogen value chain (generation, compression, storage, transport and use of green hydrogen). It addresses the research of technologies, materials and processes to reduce its energy and economic cost and minimize its carbon footprint.

The project consortium, led by Hiperbaric, is also composed of the industrial companies Aciturri, Adisseo, Ariema, Desmasa, DGH and MTorres, leaders in their respective sectors. In addition, it will have the support of thirteen Public Research Organizations, including technological centers and leading universities at a national level.

Aciturri, with a budget of 1.3 M€, leads the research of storage solutions for transport, distribution and service of hydrogen at high pressure. The hydrogen storage solutions to be developed within the project are classified into type IV and V tanks for mobile, stationary and intermodal transport solutions, to be applied for high pressures (700 bar) and large dimensions (5 - 11 m). It is estimated that progress at the end of development will allow raising gravimetric efficiency to over 7%.


Design, manufacturing and testing of a mid-size space launcher cap.

The SHERPA project involves the design, fabrication and testing of a medium-size space launcher cap. The cap is the structural element located at the tip of the launcher and whose mission is to protect the payload during launch and to permit, once in orbit, the release of the payload. For this purpose, it is manufactured in two half-shells that open at the right moment, by means of precise and guided movements, so that in no case do the parts hit each other or damage the launcher or the payload.

Aciturri's mastery of composite materials in all their phases has made it possible to identify a potential business opportunity, as a significant reduction in the weight of the structure and its recurring cost is expected with respect to the copings currently in use.

During 2022, progress has been made on the designs and structural calculations of the element and the fabrication in carbon fiber of the two half copings for testing has started. The project will be completed in 2023, with the functional testing of the coping, which will have to meet the requirements indicated by potential customers.
