Exploration of a Reverse Turbo-Brayton Cryocooler for Carbon Neutral Aeronautical Applications: Integrated Cryocooler Design and Tank Modeling for Cryogenic Liquid Hydrogen in Long Range Flight

Climate change is a pressing issue. Hydrogen aircraft are an excellent alternative to current kerosene aircraft, and appear to be the most viable long-term solution for net-zero flight. One of the main challenges for hydrogen aircraft is to sustain a low boil-off rate. This research explores the solution of active cooling of the LH2 mixture in...
