Introduction
William A. Duncan is a notable inventor based in Huntsville, Alabama, recognized for his contributions to the field of chemical engineering and propulsion systems. With a total of four patents to his name, Duncan has made significant advancements in technologies that enhance the efficiency and effectiveness of gas flow systems.
Latest Patents
One of Duncan's latest patents is a chemical pump with an integral diffuser. This innovative device is designed for pumping supersonic gas flows and consists of a chemically activated material that reacts with the gas mixture being pumped. The device includes thermal ballast material and a hermetically sealable vessel to contain the chemically active material. The internal surfaces of the pump are engineered to create gas flow passages that accept supersonic gas flow, induce a stable normal shock, and diffuse the resulting subsonic flow. This design effectively distributes the low-velocity, subsonic gas flow to the reactive chemical pump material. Another significant patent involves the use of methoxylamine hydrochloride as an additive to liquid monopropellant compositions, including hydrazine. This innovation lowers the freezing point of monopropellants, making them usable in gas generators at very low temperatures.
