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...

Mass optimisation of cryogenic fluid systems for long-duration space missions

After the space race to the Moon, Mars has been chosen the new destination to be explored by mankind. Cryogenic propellant is necessary to make space beyond the Moon accessible. Boil-off of cryogenic liquids raises the initial mass of spacecraft by increasing the amount of propellant required to carry-on. Therefore, mitigation of boil-off is key...
