Tankage fraction
Webcases in this study, the tankage fraction was assumed to be 0.09 for NBPH 2 and 0.03 for either TPH 2 or SLH 2. For liquid oxygen, the launch loads also determine the tank-age … WebTF Tankage fraction systems will have heavy tankage mass fractions (storage system mass/LH2 mass) of 40% or more. Conversely, storage of LH2 at subcritical conditions, of the order of 25-30 psia, can be achieved with very lightweight minimum *Engineer/Scientist-Specialist, Member AIAA gage LH2 tanks. As will be shown below, such subcritical
