The IRON LIQORNE project is advancing innovation in sustainable aviation by developing cutting-edge liquid hydrogen (LH2) fuel technologies for aircraft. With the ambitious goal of achieving net-zero emissions by 2050, we are harnessing LH2’s potential as both a fuel and a cooling fluid. This approach reduces component sizes while utilizing LH2’s high specific heat capacity to cool high-temperature components, such as the combustion chamber. Unlike traditional systems that rely on gaseous hydrogen, our project focuses on maintaining LH2 in its liquid form for longer, offering higher energy density and enabling extended flight operations.
Our innovative approach involves using engine heat to efficiently vaporize LH2 just before it’s injected into the combustion chamber. This unique method improves efficiency by up to 10 %, as it eliminates the need for energy-intensive upstream gasification. Furthermore, cutting-edge technologies like 3D-printed combustors, designed with numerous micro-channels for enhanced LH2 vaporization and engine cooling are investigated.
The IRON LIQORNE project also addresses key safety concerns. Safety and performance are at the forefront of our work. Key features include a booster pump and splitter valve that allow for rapid throttle response, ensuring the system is both powerful and safe. This includes preventing ice buildup caused by the extreme cold of cryogenic systems as well. With our adaptable LN2 (liquid nitrogen) research test bed, we are exploring alternative fuels and validating new burner designs, making this research essential for the future of aviation. Building on our earlier LIQORNE project, we’ve developed a comprehensive simulation model for mid-range aircraft, with plans to adapt it for various missions and aircraft types.
By combining advanced simulations, innovative hardware, and strong industry partnerships, we aim to revolutionize the use of LH2 in aviation, making it both efficient and safe. Our vision as T&T Aircraft Propulsion Systems Team is to establish Austria as a leading hub for hydrogen-powered aviation research and to push the next generation of engineers and scientists for sustainable aviation.
The IRON LIQORNE project is co-funded by the FFG. The FFG is the central national funding organization and strengthens Austria’s innovative power. werden schließlich genutzt.
