本文介绍了确定运载火箭复合材料低温贮箱允许氢渗透率方法的发展。提供了关于氢渗透测试的发展的背景信息，并且描述了最近开发的渗透测试设备。计算结果的各种坦克的设计和渗透故障模式。可重复使用运载火箭和一次性使用运载火箭都考虑了贮箱设计。与系统性能和特定的设计功能有关的故障模式得到解决。计算出的允许渗透率的比较，最近的渗透试验数据上获得的NASA空间发射计划。
This paperdescribes thedevelopment ofmethods todetermine allowable hydrogenpermeation rates for composite cryogenic tanks for launch vehicles. Background information on the development of hydrogen permeation testing is provided and permeation testing apparatus developed recently is described. Calculated results for a variety of tank designs and permeation failure modes are included. Tank designs are considered for both reusable and expendable launch vehicles. Failure modes related to system performance and to specific design features are addressed. A comparison of the calculated allowable permeation rates is made to recent permeation test data obtained on the NASA Space Launch Initiative program.
