The Phase 1 effort described has resulted in a set of preliminary criteria for quick disconnect QD couplings for use with fluorine and fluorine containing oxidizers. A number of vehicle systems were examined to determine the fundamental requirements for couplings. Also, data were obtained from literature, Government and industry contacts. and contractor studies. Identified are the requirements imposed on a typical upper stage oxidizer fill- and-drain QD by vehicle and AGE considerations, disconnect technology capabilities, specific information voids identified during this study, and program plans for Phases 2 and 3. The criteria established suggest that the design, fabrication, and testing of a fluorine QD can be undertaken with great confidence that the resulting product will serve its intended purpose. Phases 2 and 3 provide for demonstration of these criteria by fabrication and testing of two fluorine test model QDs, establishment of a preliminary military specification for a fluorine QD, and delivery of a prototype fluorine QD.
