  • Turbine components
    Patent number: 7137781
    Abstract: A turbine component, such as a turbine blade 1, 21, has a coolant supply passage 4, 24 and a cooling chamber 3, 23 connected by an injection passage 5, 25. The cooling chamber 3, 23 includes flow guides in the form of vanes 7, 8 or grooves 37 which act to create a coolant flow in a spiral direction. Thus, there is limited coolant flow impingement and greater cooling effect to allow the turbine component to operate at higher temperatures.
    Type: Grant
    Filed: November 6, 2003
    Date of Patent: November 21, 2006
    Assignee: Rolls-Royce plc
