THE DESIGN, TESTING, AND INSTALLATION OF WS 107A PROPELLANT-LOADING SYSTEMS
Abstract
Solutions to problems with the noise sensitivity of liquid sensors and the differential-pressure gauges for the LO2 filters were proposed. A pro cedure for leak-testing the helium system was adopted. A vent-valve cycling exercise in order to evaluate rapid recycling possibilities and compiled temperature data for the helium recovery system was also conducted. The liquid sensor pro gram is approaching completion and the final report is expected to be published in June. Anal ysis of the helium recovery system has been com pleted and the basic problem, brittle fracture of inlet connections through excessive cooldown, has been found unlikely to occur. We have analyzed the limitations to rapid recycle of the PLS and suggested an approach. Other studies conducted during the reporting period included bolt-torquing tests for flange bolts in the PLS LO2 piping system, an approach for analyzing flow rates by reducing the flow circuits to equivalent valve flow coefficients, and the verification of the following: minimum values for the contents of PLS vessels during load - reload operations, depletion within tolerance during standby, and sufficient helium in titanium spheres aboard the missile.
