He holds two patents that showcase his innovative approach to engineering challenges in gas turbine engines. His work has significantly impacted the efficiency and performance of turbine systems.

Latest Patents

One of his latest patents is titled "Outer case cooling for a turbine intermediate case." This invention involves a turbine intermediate case where a turbine bearing support and an inner case are centrally supported within an outer case by radially inward extending hollow struts. The design includes an inner case that carries a diaphragm and seals, defining a vent cavity surrounding a bearing compartment. Air leaking past the seals is collected in this vent cavity and flows through the hollow struts, which are utilized for impingement cooling of the outer surface of the outer case.

Another notable patent is the "Seal for variable plug two-dimensional nozzle." This invention is designed to prevent leakage at the interface of a movable plug with articulated panels and the side wall of a two-dimensional nozzle for a gas turbine engine. The seal effectively prevents high-pressure cooling air from escaping to the lower pressure exhaust gases. It comprises judiciously located dam-like members installed in the vent slots in the side wall, fabricated from Finwall material, which achieves indirect heat exchange and film cooling.
