Latest Patents

Hwang's latest patents include a system and method for improved engine cooling in conjunction with an enhanced gas bearing face seal assembly. This innovative design addresses the cooling needs of gas turbine engines, which feature a multi-stage compressor that discharges air for expansion by a combustor. The patent describes a cavity that is aerodynamically linked to a turbine stage, formed by a metal structure that connects to a seal, effectively inhibiting the flow of compressor discharge air into the cavity. Additionally, a conduit links an intermediate stage of the multi-stage compressor to the cavity, facilitating effective cooling of both the cavity and the turbine stage components.

Another significant patent by Hwang is the expanding circumferential seal with an upper-cooled runner. This design incorporates one or more expanding carbon rings and a rotating runner that is concentric to and radially outside of the carbon rings. The innovative cooling system injects oil directly onto the outer circumferential surface of the runner, shielding the seal interface from the cooling oil. Furthermore, a disk pump mounted on the main shaft enhances oil scavenging, reducing the amount of oil that reaches the seal interface.
