  6. Development of Cryogenic Insulation Material for Liquefied Hydrogen • Cryogenic Insulation Requirements • Thermal: heat flux < 0.2 W/m² h  minimized boil-off mass  low therm.conductivityespeccially in cryogenic regime required. • Resistance against aerothermal heating: > 10kW/m² & higher  no significant degradation low flammability  self extinguishing. • Thermal expansion: difference in thermal expansion of substrates and insulation shall be low. • Cryo-pumping: low or negligible  influenced by morphological structure • Mechanical properties: • Tensile strength (avoid crack formation due to thermal and pressure loads), • Compressive strength  difficult in cryo regime, • Shear strength  loads from flow field in outer layer and I/F to substrate. • Permeability: limit concentration of hazardous gases and those which can degrade thermal performance  compatibility to purging gases (He + N2). • Mass & volume: m< 2.2kg/m², thickness < 60mm. • Other requirements: pollution during ground & flight  recurring costs. • Workshop „Hydrogen and Fuel Cells in Research and Application” , Oct.4-5, 2012, Riga

  11. Development of Cryogenic Insulation Material for Liquefied Hydrogen + Theupper layer of spray PUR performs mainly the heat protection functions The middle layer during the flight should perform mainly the functions of a good thermal insulation material The layer adjacent to the metal (the cold part), are especially important – this layer should be capable of resisting the tensile stress, which arises as the LH2 tank is fuelled - • Workshop „Hydrogen and Fuel Cells in Research and Application” , Oct.4-5, 2012, Riga
