SUPPLEMENTARY NOTESReport contains color. PA Case Number: 88ABW-2011-3415; Clearance Date: 14 Jun 2011. ABSTRACTThe overall aim of this effort was to provide fit-for-purpose testing and subject matter expertise to UTC and AFRL to support the evaluation of emerging synthetic aviation fuels. The report contains information on the evaluations of various synthetic aviation fuels including: Sasol IPK, R-8 HRJ SPK, R-8x HRJ SPK, Boeing Flight Fuels, Camelina HRJ SPK, Camelina/JP-8 (HRJ8), R-8/Jet A, Tallow HRJ SPK and Tallow/JP-8 (HRJ8). In addition, miscellaneous analyses including dielectric constants of the synthetic aviation fuels, lubricity, Ignition Quality Tests (IQT), JP-8+100 fuel/water separation tests (SAE J1488) and existent gums are reported. It is concluded that the testing performed to date provides strong evidence that blends composed of 50% synthetic aviation fuel (FT IPK and HRJ SPK) and 50% petroleum-based fuel will be more than adequate as drop-in replacements for current petroleum-based fuels.

Executive SummaryThe overall aim of this effort was to provide fit-for-purpose testing and subject matter expertise to UTC and AFRL to support the evaluation of emerging synthetic aviation fuels. This report contains information on the evaluation of various synthetic aviation fuels including: Sasol IPK, R-8 HRJ SPK, R-8x HRJ SPK, Boeing Flight Fuels, Camelina HRJ SPK, Camelina/JP-8 (HRJ8), R-8/Jet A, Tallow HRJ SPK and Tallow/JP-8 (HRJ8). In addition to standardized testing, detailed studies were carried out in the following areas: dielectric constants, lubricity, ignition quality, fuel/water separation, and ...
This program assessed the effectiveness of adding anti-oxidant (AO) to various fuels after the fuels leave the refinery. The project involved storing severely hydro-treated fuels for a period of 12 months to simulate the 36 month storage period for vehicles and equipment aboard pre-positioned ships. One fuel contained AO from the refinery and an additional fuel was procured without AO added at the refinery. Each fuel was divided in half with one half being stored as received at 43C and the second half treated with the JP-8 additive package and stored at 43C. The fuel without the AO had AO added upon receipt at TFLRF. A third fuel was added to the matrix that was provided from Australia. This fuel was thought to exhibit poor storage stability characteristics. As with the other fuels, this fuel was divided into two portions with one stored as received and the other additized with the JP-8 additive package and stored at 43C. 15.
