Abstract: A rotor blade is disclosed herein. The rotor blade comprises a nominal surface profile substantially in accordance with Cartesian coordinates X, Y and Z as set forth in TABLE 1. Wherein X and Y are distances in millimeters which, when connected by smooth, continuing arcs, define airfoil profile sections at each distance Z in millimeters. The airfoil profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.

Abstract: A mounting system for a liner within a combination chamber of a gas turbine, where the liner is secured at one upstream end to a burner and at an opposite downstream end to a transition duct, the mounting system comprising: a first elastic head comprised of a first ring-shaped housing having first and second pluralities of radially spaced, axially extending teeth, with a first annular groove between said first and second pluralities of teeth, wherein said first elastic head is secured to said upstream end of said liner, with an end portion of said liner received within said first annular groove; and a second elastic head comprised of a second ring-shaped housing having third and fourth pluralities of radially-spaced, axially-extending teeth, with a second annular groove between said third and fourth pluralities of teeth, wherein said second elastic head is secured to said downstream end of said liner, with an opposite end portion of said liner received within said second annular groove.

Abstract: Fixing system (1), inside the combustion chamber of a gas turbine with low polluting emissions, of a liner or flame pipe equipped with two cylindrical elastic heads (5) each wedged at the end of the flame pipe (10) to allow its thermal expansion by lowering the thermal tensions due to the different expansion coefficient with the combustion chamber.
