Air Force Office of Scientific Research Arlington AFB VA (AFNS) Feb 10, 2010 The Air Force Office of Scientific Research and the National Science Foundation are funding research that may result in a military turbine aircraft that for the first time ever will produce its own electricity from exhaust heat generated from thermo electricity. Dr. Daryoosh Vashaee and a team of co-researchers at Oklahoma State University's Helmerich Advanced Technology Research Center in Tulsa are using thermo electric nanotechnology to investigate the conversion of waste heat into electricity. Up to this point, thermo electricity has not been used extensively beyond space and cooling applications because it could not be produced efficiently. However, the scientists' efforts in Oklahoma may soon change that and thermo electric technology may be heralded by the Air Force in a way that no other eco-friendly energy source has, because it has non- toxic emissions. Vashaee and his co-researchers are examining thermo electric versus infrared technology, which is what the Air Force is currently using. The latter requires liquid nitrogen to cool down the infrared cells. Thermo electricity, on the other hand, would not make that necessary and it would also be inexpensive. "The new thermo electric sensors also provide a means to make high performance infrared detectors that are structurally simple and small, suitable for being used in military missions," said Vashaee. Vashaee noted that the next step is to develop thermo electric modules that can be used for power generation for Air Force aircraft, solar, thermal cells and waste heat recovery systems used in industry.

Lasers Creates New Forms of Metal and Enhances Aircraft PerformanceArlington AFB VA (AFNS) Feb 09, 2010 Dr. Chunlei Guo and his team of Air Force Research Laboratory-funded researchers from the University of Rochester are using laser light technology that will help the military create new forms of metal that may guide, attract, and repel liquids and cool small electronic devices. The researchers discovered a way to transform a shiny piece of metal into one that is pitch black, not by paint, ... read more |
