A study was performed to determine venting design criteria for space shuttle payloads using worst case ascent, payload bay pressure profiles. This study incorporated the analytical model from an earlier study by Mironer and Regan, along with a number of worst case ascent pressure profiles provided by NASA/JSC. For each pressure profile, the resulting differential pressures were determined for a number of vent geometries. The maximum differential pressures for each profile were then plotted and overlayed as a function of the vent geometry. The results are summarized as a single curve that indicates the maximum differential pressure which can be expected for a given vent geometry. This curve should serve as a guideline for used in payload venting design.
