Abstract:

A discussion is presented on the evaporated propellant EP and main tank injection MTI systems for main propellant tank pressurization. Results of testing with liquid H, liquid N, UDMH, NTO N2O4, N2H4, 50-50 UDMHN2H4, RP-1, BrF5, ClF3 and B5H9 are presented. The MTI method of tank pressurization is believed feasible for the following combinations NTO into UDMH NTO into 50-50 UDMHN2H4 UDMH into NTO 50-50 UDMHN2H4 into NTO N2H4 into NTO ClF3 into B5H9. The EP method appears practical for liquid H, liquid O and NTO, while the MTI method appears practical for the combination NTO and 50-50 UDMHN2H4, and NTO and UDMH in either the fuel or oxidizer tank.
