Abstract: A combustor can include: a combustion chamber; a cap covering the combustion chamber; a first swirler inlet cup passing through the cap and having a first length and a first bell mouth; a second swirler inlet cup passing through the cap and having a second length and a second bell mouth; and a third swirler inlet cup passing through the cap and having a third length and a third bell mouth, wherein the first length is different from the third length, and wherein the first bell mouth is different from the third bell mouth. The first, second, and third swirler inlet cups can have different diameters, respectively.

Abstract: A flow conditioner in a combustor of a gas turbine comprises a body and a flow conditioning portion configured to be placed in an air path providing air flow to a combustion chamber, the flow conditioning portion including a plurality of holes tuned to a damping frequency to dampen a pressure fluctuation caused by combustion dynamics from the combustion chamber.

Abstract: An apparatus 10 for determining the position of a shift rail 12 which is employed within a vehicle having a transmission 14. Apparatus 10 includes an offset lever or member 18, and a pair of proximity sensors 30, 32 which detect the distance between the sensors 30, 32 and the respective surfaces 21, 23 of member 18, and which selectively generate signals corresponding to the measured distances. A controller 38 receives the generated signals and utilizes the signals to determine the linear and angular position of shift rail 12.
