Main Propellant Tank Pressurization System Study and Test Program.
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 UDMH/N2H4, 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 UDMH/N2H4; UDMH into NTO; 50-50 UDMH/N2H4 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 UDMH/N2H4, and NTO and UDMH in either the fuel or oxidizer tank.
