Effects of Alternative Fuel on Emissions from Gas Turbine Engines

A joint AFRL-industry-university research team is studying the effects of alternative fuels on production of air pollutants in gas turbine engines.  The objectives of this program are to establish a science base needed to develop accurate models for emissions from alternative fuels and a science-based methodology for selecting practical alternative fuels that minimize emissions.   The research approach involves closely-coupled experimental and computational efforts in a wide range of experimental facilities from shock tubes to model combustors.  A key element of the approach is a surrogate fuel set carefully selected to encompass the range of compositional variation expected among aviation fuels from alternative sources. 


Thomas Litzinger is a Professor of Mechanical Engineering at Penn State, where he has been on the faculty since 1985. His research encompasses studies of solid propellants, internal combustion engines, and gas turbines with a focus on effects of fuel composition on emissions and performance.  This research has been funded by the multiple DoD agencies including the Office of Naval Research, the Army Research Office, the Air Force Office of Scientific Research, and the Strategic Environmental Research and Development Program.   He has published more than 150 articles related to combustion. He is a Fellow of ASME and ASEE.
