Abstract:

The operation instructions, prototype testing program, and the manufacturing procedures required to develop a prototype unit are presented for a Mylar film bladder for liquid hydrogen expulsion. A 27-gallon, liquid hydrogen expulsion unit was fabricated to test a series of three-ply Mylar bladders. The test program describes the data required and the test setup used to determine the heat transfer rate and the operational characteristics of the prototype system. A summary of problem areas, bladder failures and gas pressure regulator malfunctions has been included together with possible solutions. The report is summarized with a list of recommendations for future expulsion units. Author
