Latest Patents

Sirignano holds a patent for a "Miniature, liquid-fueled combustion chamber." This invention features a combustion chamber with at least one critical dimension that is sub-centimeter. The design confines combustion within the chamber by injecting liquid fuel as a film over the entire area of the chamber walls. A preferred embodiment includes a swirl or vortex generator at the entrance of the chamber, which causes the in-flowing oxidizing gases to swirl within. The liquid fuel can be applied through orifices or a porous wall material, or it may be sprayed onto a surface within the chamber. Additionally, the liquid fuel can be augmented with an inert liquid such as water. This innovative approach enhances the efficiency of combustion processes.
