Expulsion Bladders for Cryogenic Liquids
The problems associated with the expulsion of liquid in a zero gravity environment have long been recognized. Expulsion bladders have been used successfully in ambient temperature conditions, but little research has been directed toward the development of bladders for cryogenic liquids. During the past 20 months an intensive study of materials and bladders has been conducted. During the second phase of this program, several highly successful bladders were developed and progress was made over all previous work. A detailed report of this program is given elsewhere.*
