Each rotor alternately engages with a shaft by overrunning one-way clutches and is held from turning back, through the damper, mounted on a corresponding flywheel and forming a part of the flywheel assembly, which is rigidly attached on the shaft. The assembled rotors from the outside are rigidly closed by flanges on each of which is mounted at least one blade. The blades are positioned into formed cavities between the rotors and caps of the housing, thereby forming two cooling cavities through which coolant circulates around rotors through openings in the housing and through longitudinal grooves in the shaft. On the vanes are mounted cylindrical and conical seals, which remove the need for lubrication. | 2022-01-20 |

20220018284 | SYSTEMS AND METHODS TO ENHANCE INTAKE AIR FLOW TO A GAS TURBINE ENGINE OF A HYDRAULIC FRACTURING UNIT - Systems and methods to increase intake air flow to a gas turbine engine of a hydraulic fracturing unit when positioned in an enclosure may include providing an intake expansion assembly to enhance intake air flow to the gas turbine engine. The intake expansion assembly may include an intake expansion wall defining a plurality of intake ports positioned to supply intake air to the gas turbine engine. The intake expansion assembly also may include one or more actuators connected to a main housing of the enclosure and the intake expansion assembly. The one or more actuators may be positioned to cause the intake expansion wall to move relative to the main housing between a first position preventing air flow through the plurality of intake ports and a second position providing air flow through the plurality of intake ports to an interior of the enclosure. | 2022-01-20 |
20220018285 | MULTI-RING SPACER FOR GAS TURBINE ENGINE ROTOR STACK ASSEMBLY - A multi-ring spacer includes a first ring having a first clocking position, a second ring coaxial with the first ring, and having a second clocking position. A total kink angle of the multi ring spacer is dependent on an angular deviation of the second ring's clocking position relative to the first ring's clocking position. | 2022-01-20 |
