Brochure: Wind tunnel modelling and testing

When an aircraft model enters a wind tunnel, it’s a decisive step in development. Years of development, simulation and numerical analysis are about to face measurable reality.

NLR ensures every campaign is carefully prepared and executed. Wind tunnel models are custom-made, combining aerodynamic fidelity, structural integrity, and measurement accuracy. NLR delivers high-quality models with decades of experience, refined processes, and multidisciplinary expertise. NLR enhances testing with advanced measurement techniques, such as flow visualization and acoustics, precision custom load balances, and tailored remote control and data-acquisition systems. Its materials expertise spans composite components, metal 3D-printed parts, and propeller blade manufacturing. Smart test design and simulation reduce risks before testing begins. These models are not just built — they are built to perform.

NLR’s services are independent of specific wind tunnels. We collaborate with DNW to execute campaigns efficiently. Our collaboration ensures smooth project execution and deliver efficient programmes that provide valuable data for next-generation aircraft.

Booklet: Composites Research and Development

A key objective for more efficient and sustainable aircraft is to make lightweight, durable and affordable parts which are designed for ease of maintenance. To be allowed to use parts made of new materials like composite and metal additive printed components in an industry like aviation, all of the materials must be accompanied by the right certification. NLR takes care of the entire process, from calculation and design all the way through to manufacturing, repair and certification. NLR assesses material properties, develops structural concepts and manufacturing technologies, designs components and builds parts up to the level of full scale prototypes. Spanning the entire spectrum of product development is what makes NLR unique.

Booklet: R&D More electric and hydrogen-electric powered aerospace

Hydrogen as a fuel is considered to be an important route towards future sustainable aviation. For aviation
applications, hydrogen presents several key advantages: it allows for the elimination of carbon emissions in
flight and along the entire life cycle. Its usage in fuel cells allows eliminating NOx and particles. When burnt
in a turbine engine, very low particle emissions can be expected, as well as reduced NOx emissions, provided that the combustion system is optimised. However, water vapour emissions need to be carefully managed.

Booklet: Overview space capabilities

Royal NLR works closely with industry and government to design satellites, payloads and launchers systems, as well as subsystems, such as thermal control systems, electronics and antennas. We also invest in state-of-the-art facilities to accelerate our research and develop new space capabilities by leveraging our expertise in aerospace-qualified lightweight composite structures, multi-metal additive manufacturing, and the effective use of Earth observation and satellite navigation data for both civil and military applications.
