    Abstract: PROBLEM TO BE SOLVED: To provide a general cooling mechanism for an industrial gas turbine engine to provide an allowable heat transfer effect and manufacturing cost. SOLUTION: A coolable rotor blade 42 having an air foil 64 provided with two snaking channels 122, 124 is disclosed. Various structural details are developed to cool a front edge region 68 and a rear edge region 74 of the air foil 64. As one detailed example, an air foil trip strip in the channel has a constant height and a constant pitch along leg parts of most of the channels except for the leg parts 122c, 124c nearest to the edge regions 68, 74 of the air foil 64.

    Abstract: A gas turbine engine includes a very high speed low pressure turbine such that a quantity defined by the exit area of the low pressure turbine multiplied by the square of the low pressure turbine rotational speed compared to the same parameters for the high pressure turbine is at a ratio between about 0.5 and about 1.5. The high pressure turbine is supported by a bearing positioned at a point where the first shaft connects to a hub carrying turbine rotors associated with the second turbine section.

    Abstract: A gas turbine engine includes a shaft defining an axis of rotation. An outer turbine rotor directly drives the shaft and includes an outer set of blades. An inner turbine rotor has an inner set of blades interspersed with the outer set of blades. The inner turbine rotor is configured to rotate in an opposite direction about the axis of rotation from the outer turbine rotor. A splitter gear system couples the inner turbine rotor to the shaft and is configured to rotate the inner set of blades at a faster speed than the outer set of blades.
