  • Gas-turbine blade featuring a modular design
    Patent number: 8100653
    Abstract: A gas-turbine blade has a root 5 and an airfoil 2, with the airfoil 2 including an internal load carrier 6 as well as an airfoil element 8 enclosing the internal load carrier 6 by forming a cavity 7 extending along the longitudinal blade axis. The load carrier 6 is designed as a central element without cooling ducts and cooling air is introduced into the cavity 7 via the root 5.
    Type: Grant
    Filed: June 12, 2008
    Date of Patent: January 24, 2012
    Assignee: Rolls-Royce Deutschland Ltd & Co KG
    Inventors: Jeffrey-George Gerakis, Peter Davison
  • Fuel injection device for an aircraft gas turbine
    Patent number: 7694899
    Abstract: A fuel injection device for fuel injection systems, e.g. for aircraft gas turbines, includes at least one fuel injection opening, through which a continuous flow of fuel 1 is issued, with the fuel injection opening having a non-circular cross-section.
