Title: Innovations of Aaron S. Hu in Gas Turbine Technology
Introduction
Aaron S. Hu is a notable inventor based in Hartford, CT, who has made significant contributions to the field of gas turbine technology. With a total of 5 patents to his name, Hu's work focuses on enhancing the efficiency and reliability of combustion systems in gas turbines.
Latest Patents
One of Hu's latest patents is a pilot injector for gas turbine engines. This innovative combustor is designed to avert engine flameout by incorporating a combustion chamber with an outlet for discharging heated combustion products. The combustor features a primary injector that injects fuel and compressed air into a primary zone, inducing fuel into a recirculation zone. Additionally, it includes combustion means for combusting the fuel and compressed air, resulting in heated combustion products. The combustor is equipped with sensing means to monitor for pre-flameout conditions and a pilot injector that responds to these conditions by injecting a propellant into the recirculation zone, allowing for combustion as a diffusion flame.
Another significant patent by Hu is the tangential entry fuel nozzle. This premix liquid fuel nozzle has longitudinal air entrance slots into a cylindrical chamber, with a centerbody that produces an axially increasing flow area toward the chamber outlet. Liquid fuel is atomized in a specified location adjacent to the conical centerbody, where high axial shear velocity ensures thorough vaporization and uniform mixing before combustion.
