Vulnerability of Airborne Cryogenic Fuel Tanks.

Abstract : This report examines certain aspects of cryogenic fuel tankage specifically liquid hydrogen (LH2) use in aircraft. These aspects include background properties, production methods and cost of LH2; tankage configuration and associated problems and description of candidate tank wall specimens fabricated for AFFDL/PTS in-house test program. It is concluded that liquid hydrogen presents new potential hazards that require further study to determine their vulnerability.
