ROCKET PROPELLANT INPLACE FLOWMETER CALIBRATION SYSTEM, PROPULSION ENGINE TEST CELL (J-3)

Abstract

The inplace flowmeter calibration system of Propulsion Engine Test Cell (J-3) is described, emphasizing the current equipment, calibration techniques, and the calibration results obtained. The system is a gravimetric pressure-fed propellant system which provides inplace calibration of turbine- type flowmeters with storable liquid propellants at the same temperatures, pressures, and flow rates experienced during rocket engine testing. Data from over 640 calibration data points have been statistically analyzed. Average absolute system errors for calibration with nitrogen tetroxide and a 50-50 hydrazine-UDMH blend were plus or minus .18 and plus or minus .21 percent, respectively, based on one standard deviation.
