Abstract : As a part of a liquid propellant positive expulsion program an investigation was made of a process for forming a rollonet within a propellant tank after the tank is fully assembled. The process used the chemical vapor deposition of aluminum, by thermal decomposition of aluminum alkyl, on the heated interior of the tank walls to form the rollonet. Details of experimental equipment, procedures and processes, and test results are discussed. The results of detailed material evaluation on samples of deposited aluminum are presented in photomicrographs, tabulated physical properties data, and X-ray examination photos. (Author)
