Aerospace Jet Fuels: JP-8 (3773) vs. JP-8 (4177)

  1. May 19, 2011 #1
    Can anybody point me in the direction of some documentation that can help me to distinguish between these two fuels? I have been searching for hours and I keep coming across articles that use these as sample fuels in experiments, but none that actually describes the numbering convention?

    I understand that JP-8 Jet A + additives, but what are the differences between the JP-8's themselves?

    I have also see it as JP-8 POSF 3773 and JP-8 POSF 4177.

    Any help is appreciated.

    The POSF numbers appear to be identifiers for specific fuel samples from Wright Patterson A/F Base, produced by different methods.

    This gives the composition of 3773 (and two others, but not 4177).

    I suspect there isn't any "numbering convention", except that 3774 is the next sample after 3773.

    Presumably WPAB keeps a database ...
