This program is an analytical study correlating fuel properties and engine design and operating parameters with engine combustion performance and hot section combustor and turbine durability. Standard fuel specification data and fuel composition data are considered, along with special fuel properties and characteristics not routinely measured. Engine combustor design parameters considered are fuel injection and atomization, fuelair mixing, residence times, temperatures and pressures, and flow velocities and other important design parameters. Engine performance parameters include low temperature starting and high altitude relight, flame stability i.e. lean blow-off limits, combustion efficiency, exhaust emissions including smoke, and thermal loading of the combustor liner and turbine nozzles. Data for this program were obtained from recent and current Aero Propulsion Laboratory sponsored programs, NASA programs, and similar work performed by other Government agencies and industry.
