Title: Innovations by Junhaur Jih
Introduction
Junhaur Jih is a notable inventor based in Cincinnati, OH (US). He has made significant contributions to the field of gas turbine engines, holding a total of 3 patents. His work focuses on enhancing engine performance and reducing emissions through innovative designs.
Latest Patents
One of Junhaur Jih's latest patents is the "Anti-ice splitter nose," which discloses a splitter apparatus for gas turbine engines. This apparatus includes a splitter with an annular outer wall that defines a convex leading edge. It features an annular splitter support positioned radially within the outer wall, which includes a forward end against a splitter inner. The design incorporates a first bulkhead that spans between the outer wall and the splitter support, creating a generally annular splitter plenum. The airflow is effectively managed through spaced apart, radially oriented metering slots and exit slots, enhancing the overall efficiency of the engine.
Another significant patent is the "Combustor rear facing step hot side contour method." This innovation involves a combustor liner with a stepped surface and an overhang portion that forms an air cooling slot. The contoured rear-facing edge of the overhang reduces turbulence in combustion gas flow and minimizes the combustor liner's surface area exposed to combustion gases. A thermal barrier coating applied to this edge further reduces heat flow, thereby lowering the operating temperature of the combustor liner. This advancement not only reduces the amount of cooling air needed but also decreases exhaust emissions, increases engine performance, and extends the combustor assembly's working life.
