STUDY OF PHYSICAL PROPERTIES NECESSARY FOR SATISFACTORY FUNCTIONING OF AN O-RING

Abstract

Results are presented of a study of physical properties necessary for satisfactory functioning of an O-ring. Also included are details of a revised computer program for the study of aging characteristics of O-rings. Other than acceptable fuze leakage, no hydraulic oil or gaseous nitrogen leaked past the Atlas lume tank pressurizing value, fuel disconnect valve, or main fuel valve from installing aged O-rings in the valves. No correlation between O-ring property levels and functions was attempted because of the satisfactory performance demonstrated by O-rings during component leakage checks, but further studies should be conducted to obtain these correlations. Special test fixtures should be designed and built to permit the best utilization of test time and available funding. (Author)
