Hydrogen Aeronautic Applications

The industry today
When it comes to the use of valves in aerospace applications, you probably think of diminutive sizes used in flying equipment such as R&D launchers, satellites or rovers. Yet demand is far higher – and product size far bigger – when it comes to ground operations. Cryogenic valves are often used for launcher filling or rocket engine test benches. Typical media are oxygen and hydrogen at cryogenic or ambient temperatures, depending on the position along their supply line. Helium may also be used for purging, and nitrogen for additional fire protection, but both in comparably smaller quantities than the combustibles.

Green energy and future needs
The aeronautics industry was one of the first to use hydrogen as a propellant – thus contributing to the decarbonisation of the atmosphere – and the development of hydrogen-powered rocket engines continues, in combination with increasing loads.
Engine test benches are increasingly required where the storage of large quantities of gases must be distributed to lower the risk of explosion. Distributed storage necessitates large-scale piping networks designed to transport the media to the place of use. As rapid delivery is essential, valves with large nominal diameters, high operating pressures and high flow rates are essential.

Our mission
STÖHR is committed to having a positive impact on the environment and offers solutions for hydrogen-based transportation systems at all medium temperatures, valve sizes and pressure levels for both space-bound mobile applications and stationary use at rocket engine test benches or launcher filling stations. Get in touch to discuss your design concept and we’ll work with you to design, prototype and manufacture the fittings and installations you need for mass production. We’re open to your challenge!
