Latest Patents

David W Sullivan holds a patent for a bipropellant gun and method of firing the same. This invention involves a bipropellant gun where an immiscible hydrocarbon fuel and oxidizer are combined in the gun's combustion chamber just prior to, or simultaneously with, ignition. The oxidizer consists of hydrogen peroxide with a concentration of less than 73 percent by weight. In one embodiment, the oxidizer is bulk loaded into the combustion chamber, and a powdered solid hydrocarbon fuel is dispersed into the oxidizer using a pyrotechnic igniter. Another embodiment emulsifies the oxidizer and a liquid hydrocarbon, which is then bulk loaded into the combustion chamber, with combustion initiated by a pyrotechnic igniter. Each design features a combustion chamber volume that exceeds the combined volume of fuel and oxidizer, creating a void or headspace of compressible gas that limits the rate of pressure rise.
