Hybrid Thermally Efficient Core (HyTEC) HyTEC Phase I - P&W SATF Final Report

This report details work conducted under the National Aeronautics and Space Administration (NASA) Hybrid Thermally Efficient Core (HyTEC) project intended to accelerate small turbofan engine turbine technologies. Pratt & Whitney (P&W) investigated continued development of two state-of-the-art combustor architectures: advanced Rich-Quench-Lean (RQL) and lean staged (LS) stoichiometry combustors. The primary objective of these investigations was to evaluate the impact of 100% blend synthetic aviation turbine fuel (SATF) on key engine and system performance metrics such as gaseous emissions, non-volatile particulate matter (nvPM) emissions, liner durability, combustor dynamics, and combustor operability, including combustion efficiency, lean blowout (LBO), and ignition characteristics.
