Speech Title:
Progress in Metal-Fueled Transmedia Engine Research and Future Emerging Power Systems
 
Abstract:
The metal-fueled engine is attractive in aerospace and underwater propulsion because of its rather successful combination of such characteristics as high combustion heat, density, safety of powder handling, non-toxic combustion products, and price. However, to realize these advantages, metal-fueled propellants are required to have good delivery characteristics and stable, efficient combustion. These key technologies remain a major challenge in the development of metal-fueled engines. This presentation focuses on the present development of metal-fueled engine technology and its application in transmedia vehicle, specifically covering numerical modeling of the flow field in the engine and recent experimental studies. Finally, several novel power systems with high potential for future applications in launch and transmedia vehicles are introduced.
