Abstract : The Air Force has encountered problems of storing fuel for high-speed, air-breathing aircraft. The thermal stability of high-temperature, hydrocarbon jet fuels is affected by periods of storage. During storage, jet fuels must retain their physical and chemical characteristics. Eighteen JP-6 fuels and nine Thermally Stable fuels were stored for various periods of time; data are presented on the results. After only 30 weeks of ambient storage, eight JP-6 fuels failed to pass the minimum specification requirements (Specification MIL-J-25656B) for thermal stability. All of the fuels monitored passed the thermal stability requirement when procured by the Air Force. The critical period in the life of high-temperature fuels regarding thermal stability occurs in the early storage period. Handling, transfer, and fuel deterioration are cited as possible influences on this early storage degradation. (Author)
