  • Fanned trailing edge teardrop array
    Patent number: 7377748
    Abstract: A component for use in a gas turbine engine is provided. The component has an airfoil portion with a plurality of internal cooling passages and a non-linear trailing edge. The component further has a non-linear array of teardrop shaped assemblies which form a plurality of injection slots for injecting a coolant fluid into a fluid passing over the airfoil portion. The teardrop shaped assemblies are designed to maximize thermal performance of the component by reducing a relative diffusion angle between the injected coolant flow and the streamline direction of the fluid passing over the airfoil portion.
    Type: Grant
    Filed: September 22, 2005
    Date of Patent: May 27, 2008
    Assignee: United Technologies Corporation
    Inventors: Dominic J. Mongillo, Jr., Young H. Chon, Eugene Kulak, legal representative, Raymond Kulak
