April 13, 2006 – nGimat Co., in collaboration with the Georgia Institute of Technology and the Wright-Patterson AFB Air Force Research Laboratory, has been awarded a $750,000 Phase II Small Business Technology Transfer award to develop a fuel injection method and advanced numerical simulation tools for the injection of fuel at extreme operating conditions in aero-propulsion combustion systems.
“Variation of engine operation through adjustable fuel injection control is desirable to minimize emissions, maximize efficiency or maximize performance power depending on the desired performance needs of commercial requirements or the instantaneous theater of military use. The fuel injector developed through this combined effort will have application in the commercial jet engine market as well as in the military field with the development of advanced aircrafts such as the Joint Strike Fighter,” said Andrew Hunt, CEO/CTO of nGimat. “Future military gas turbine combustors will deliver higher thrust-to-weight ratios than current designs, resulting in increased combustor pressures and temperatures. Thus in advanced aircraft engines, the highly compressed air will exist at a temperature from 300C to above 500C before fuel injection into the combustor environment. Rapid, fine control of atomization, based on incoming air and fuel property variations and desired military operation criteria, will be provided by the nGimat injectors with only moderate power requirements necessary at flow rates up to 750 lbm/h.”
At the end of Phase II, the injectors will be tested on a commonly used Department of Defense combustor made available for this effort at the Wright-Patterson AFB Propulsion facility. The results from the engine test at WPAFB will demonstrate the enhanced performance delivered by nGimat’s injector system already demonstrated in smaller combustors during Phase I, and will serve as real data for verifying the capability of the software simulation tools developed during the effort.
Successful Phase II testing will enable nGimat to license the modeling tools and supply fuel injectors to leading jet engine companies for design and use in future products.
