Abstract:

Reports on Propellant Ullage Decay ME no. 495 and Use of a Flow Conversion Nomograph for leaks and Capillaries, ME no. 484 are presented. The primary purpose of the ullage decay study was to determine a relationship between the helium leak rates and the actual ullage gas leak rates. The results of this study showed that the propellant gases flow at a rate equal to or slower than, helium. In many instances the escaping ullage gas particularly in the case of nitrogen tetroxide actually condensed in the leak path and eliminated any further gas leakage. The nomograph ME no. 484 is submitted for information on flow rate conversions. By use of the nomograph the flow rate of any liquid at any pressure through the same path. The nomograph was developed theoretically however, the gas portion has been proven experimentally.
