PROGRAM 706 TASK 4. MPU BLADDER DEVELOPMENT.

Abstract

Efort was directed to develop a non-metallic positive expulsion bladder to be used in space vehicle propulsion systems, utilizing N2O4 and a 50/50 blend of UDMH and N2O4 as the propellants. Research and tests on materials for non-metallic positive expulsion bladders have resulted in the selection of a ''bag-in-bag'' Teflon film combination in each bag, for fabrication of a set of 37-in. diameter bladders to be subjected to a series of expulsion/temperature tests. Full scale bladder tests have shown that both a ''bagin-bag'' single layer Teflon film combination and a single ''bag-in-bag'' Teflon film combination fail during propellant expulsion tests below 70 F.
