CONVAIR PROPELLANT UTILIZATION SYSTEM TESTING SUMMARY CONDUCTED ON NAA TEST STAND 1-3A, AT MSTSAN-1 4 MARTO TO 16 APRIL 1958,
Abstract
A propellant utilization (PU) test program was conducted on NAA Test Stand 1-3A during the period 4 March to 16 April 1958. Six successful propellant utilization tests were achieved during this period. The purpose of the PU system is to control propellant consumption so that no more than 465 pounds of residual propellants are left in the main tanks at sustainer engine cutoff. Separate mercury manometers sense the amount of LO2 and fuel in the propellant tanks. The manometer electrical outputs are combined in the bridge error circuit, the error being the deviation from a 2.25 weight ratio of LO2 to fuel in the tanks. After demodulation and filtering the error signal is sent to the servo system of the PU (fuel) valve. Subsequent PU valve and head suppression (LO2) valve movements correct sustainer engine mixture ratio to resolve the tank errors as sensed by the manometers. (Author)
