Rapid Response Research and Development (R&D) for the Aerospace Systems Directorate. Delivery Order 0021: Engineering Research and Technical Analyses of Advanced Airbreathing Propulsion Fuels, Subtask: Fit-for-Purpose (FFP) and Dynamic Seal Testing of Alternative Aviation Fuels

Abstract : Alternative aviation fuels derived from a number of emerging synthetic pathways were subjected to fit-for-purpose analysis and other specification testing. The fuels included in the study were of the type: direct sugar-to-hydrocarbon (DSHC), alcohol-to-jet (ATJ), hydrotreated depolymerized cellulosic jet (HDCJ), hydro-deoxygenated synthesized kerosene (HDO-SK), and catalytic hydrothermolysis (CH).
