Title: The Innovative Contributions of Thomas E. Dunigan
Introduction
Thomas E. Dunigan is an accomplished inventor hailing from Oak Ridge, New Jersey. With a total of four patents to his name, he has made significant contributions to the field of ballistic modifiers and propellant technology. His work primarily involves unique chemical formulations that enhance the performance and stability of propellants used in various applications.
Latest Patents
Dunigan's latest patents include innovative formulations that play crucial roles in enhancing the properties of double base propellants. One of his notable inventions is the "Reaction product of normal lead beta resorcylate and monobasic cupric," which is an organo-metallic ballistic modifier. This product is created as an evaporation residue from the reaction of normal lead beta resorcylate and monobasic cupric salicylate in either water or alcohol under elevated temperatures ranging from 180°F to 220°F. This modifier allows for versatile production processes, either solvent-based or solventless, enabling double base propellants to achieve a meso burning rate.
Another significant patent is the "Ballistic modifier resistant to hydrolysis," which involves a novel complex produced by mixing and interacting an organic isocyanate with lead beta resorcylate and cupric salicylate in an inert solvent. The complex, after solvent removal, can be integrated into nitrocellulose-nitroglycerine double base propellants. This yields a propellant composition characterized by excellent ballistic properties and enhanced stability against the formation of exudates, which can inhibit ignition.
