Dr. Stickler has an extensive background in fundamental combustion science, which provides a base for development of innovative concepts for thermal systems. Recent technology innovations include advanced glass synthesis; low emission coal combustion and power system integration; hybrid rocket fuel burn rate enhancement; forced unsteady combustion for gas turbine emission control; and gas turbine blade cooling. He also provides technical support for industrial implementation of these technologies.
Energy and Propulsion Technology
The Center for Energy and Propulsion Technology at ARI provides a strong interdisciplinary approach to research and technology development, focused on interactions of combustion, fluid flow and transport processes. Experimental, analytical and numerical techniques are combined both to develop innovative technological concepts and to enhance fundamental understanding of key processes. Research in this area is supported by U.S. government agencies, including the Advanced Research Projects Agency, Army, Navy and Air Force, National Aeronautics and Space Administration, Department of Energy, and by industry sponsors, including the Gas Research Institute and Hague International.

Personnel
.Dr. Annen's research is in the areas of energy conversion, combustion, heat transfer, and flowfield diagnostics. His recent research focus is the development of a miniature internal combustion engine (MICE) generator for portable electric power generation, capable of operation on JP-8, and diesel, as well as propane. He designed and performed stress analysis for the condenser and turbine disc components for a new technology vaporization-cooled turbine blade in a DARPA-funded test and demonstration program. Other research areas have included the development of improved IR countermeasures by modifying and improving the combustion characteristics of IR decoys, and the development and application of combustion diagnostics including a chemiluminescent tracer for visualization of high NOx formation regions in combustion devices, a field-portable FTIR spectrometer system, a LIBS instrument for metal alloy analysis, a high precision O2 LIF temperature diagnostic for turbomachinery, a laser Rayleigh scattering diagnostic for temperature and density, and a laser backscatter particle diagnostic that was use in one of the first in-situ measurements of particle size distribution and concentration in an industrial boiler.
