Abstract : A series of five tests was conducted to demonstrate the capability of the umbilical backup structure to withstand the loads imposed during separation of the coolant, helium, and oxygen lines, and to demonstrate the functional operation of the umbilical disconnect. The umbilical, which is similar to that used on NASA Gemini, is designed to disconnect by the rupture of four frangible unions. Because of changes from the NSA Gemini configuration in coolant hose lengths, lanyard, coolant hose 'pull off' angles, and the addition of hoses for the dual gas system, it was necessary to redesign the umbilical frangible unions for the Gemini B. Satisfactory separation was achieved during each of the five tests. A visual inspection of the umbilical backup structure after each test revealed no structural damage. (Author)
