Abstract:This document, prepared by Honeywell Aerospace, Phoenix, AZ (Honeywell), contains the final
test report (public version) for the U.S. Department of Transportation/Federal Aviation
Administration (USDOT/FAA) Alternative Fuels Propulsion Engine Durability Evaluation and is
submitted in accordance with contract data requirements list (CDRL) of USDOT contract
DTRT57-11-C-10053.
This program addresses the aviation industry’s need to evaluate the impact of alternative
aviation fuel [synthetic paraffinic kerosene (SPK)] blends on engine durability. The particular
SPK being evaluated during this effort was made from Hydroprocessed Esters and Fatty Acids
(HEFA) made from animal fats, however, other potential alternative SPK fuels include HEFA
fuels made from vegetable oils and fuel derived by Fischer-Tropsch (F-T) synthesis from
unconventional sources (such as coal, natural gas, biomass, or combinations thereof).
The evaluations performed as part of this effort included assessing the impact of a 50/50 blend of HEFA SPK fuel mixed with conventional petroleum-derived Jet A fuel on the major combustion
system components of a HTF7000 turbofan propulsion engine over the course of a 500-cycle
endurance test. The design of the HTF7000 fuel system and hot section are similar to much
larger propulsion engines in commercial and military aircraft. The similarity of the HTF7000 to
larger main engines allowed for a complete endurance test that was directly representative to
larger engines but only required the limited amount of fuel that was available for testing.
