ROCKET ENGINE VALVE POPPET AND SEAT DESIGN DATA
Abstract
Presented is a description of the work accomplished in summarizing current valve design technology and providing fundamental metal-tometal seating characteristic design data. The program was conducted in two phases. Phase I is a survey of pertinent patents, technical literature, and industry data to determine current technology levels and indicate specific areas where information was lacking or obsolete. The accumulated material produced little worthwhile information on either the mechanics of sealing or the correlation between theoretical and actual characteristics. Phase II effort involved analytical and empirical studies of the detail aspects of valve sealing. Test models were fabricated with particular emphasis placed on describing the resultant sealing surfaces. Leakage flow data were obtained for the near-seated condition resulting in good correlation with theoretical predictions. The stress-leakage relationship in the on-seated condition was empirically investigated as a function of surface and material variations, pressure, and fluid. The resulting information, together with inspection evidence supporting deduced test surface finish conditions, is presented. (Author)
