LiT Open Calls

What is the aim of the project?

LiT Open Calls aims to enable supporting research, secure a strong Dutch knowledge position, and strengthen the SME ecosystem by stimulating research, knowledge development and collaboration between entrepreneurs and between entrepreneurs and knowledge institutions. LiT Open Calls consists of four modules:

Knowledge and testing vouchers
Feasibility projects
R&D cooperation projects
Supporting research

How did the idea originate?

LiT Open Calls was launched with the aim of accelerating the transition to sustainable aviation and stimulating innovation within the sector. By offering financial support, companies and knowledge institutions are encouraged to develop and apply new technologies and sustainable solutions. In addition, the scheme specifically aims to involve more SMEs in Luchtvaart in Transitie, so that smaller companies can also play an active role in making the sector more sustainable. This not only increases innovative capacity, but also promotes collaboration between different parties within the aviation industry.

How does the project contribute to sustainable aviation?

All activities carried out within LiT Open Calls focus on electric-thermal energy systems, cost-effective manufacturing technologies for new aircraft configurations after 2030, new propulsion systems, new design concepts and materials, or ultra-efficient structural components. Each activity contributes to accelerating the transition to sustainable aviation. The knowledge generated also helps companies strengthen their position in the international supply chain through 2030 and beyond. As such, the subsidy also contributes to a stronger Dutch economy.

What steps have been taken so far?

In 2024, twelve feasibility projects and fourteen knowledge and test vouchers were submitted. Four supporting research projects were also launched:

AEROFUSION (led by Stichting SAM|XL) is conducting fundamental research into continuous ultrasonic welding of curved thermoplastic composite components for aircraft assembly.

ARGUS (led by the University of Twente) is developing adaptive winglets with ‘morphing surfaces’, based on advanced functional materials and an AI-driven control system.

CoolPipe (led by the University of Twente) is researching two-phase hydrogen flow in fuel systems, developing a non-invasive cryogenic flow meter, predictive models for different pipe geometries, and a 0D flow model for concept selection. This contributes to safe and efficient hydrogen pipelines in aviation, a crucial step towards the use of liquid hydrogen as a sustainable fuel.

IOHEVA (led by TU Eindhoven) is developing an integrated design tool to optimize hybrid hydrogen-electric propulsion systems for aircraft. The tool considers different use cases and aspects such as cost and sustainability. It is being developed by TU/e, NLR, Zepp.solutions, Tulip Tech and the AE-Groep.

What are the next steps of the project?

In 2026, new applications can be submitted for the feasibility projects, test and knowledge vouchers, and supporting research modules.
