Latest Patents

One of her latest patents is titled "Airfoil with dual source cooling." This invention features an airfoil for a gas turbine engine that includes dual pressure source cooling. The design incorporates an internal trailing edge passage and an internal leading edge passage. Compressor bleed air at higher pressure is channeled through the leading edge passage, while lower pressure air is directed through the trailing edge passage. This innovative approach ensures that inward flow of combustion products is effectively prevented.

Another significant patent is "Turbine vane having dedicated inner platform cooling." This turbine vane is adaptable for operation in various thrust regimes. It includes a hollow core that allows cooling fluid to pass through the vane, along with an inner platform that has a pocket for fluid communication with the core. Heat exchange occurs between the platform and the cooling fluid, with cooling holes extending to the flow surface of the platform to enhance cooling efficiency.
