Abstract: A turbine blade having a base and an airfoil, the base including cooling air inlets and an internal cooling air passageway, and the airfoil including an internal multi-bend heat exchange path beginning at the base and ending at a cooling air outlet at the trailing edge of the airfoil. The airfoil also includes a “skin” that encompasses a tip wall, an inner spar, and a tip flag cooling system.

Abstract: This disclosure provides a seal strip assembly for a sealing strip slot to reduce air leakage between gas turbine nozzle segments. The seal strip assembly includes a bimetal element and a backing plate. The bimetal element includes a first layer with a first thermal coefficient of thermal expansion and a second layer with a second coefficient of thermal expansion. The second coefficient of thermal expansion is lower than the first coefficient of thermal expansion allowing the bimetal element to expand with an increase in surrounding temperature.

Abstract: This disclosure provides a cross key anti rotation spacer for use in a gas turbine engine. A compressor disk assembly can have a cross key ring having a plurality of keys, teeth, or castellations, alternating with a plurality of gaps to form a cross key surface. The keys or teeth of the cross key surface can mesh with corresponding teeth formed on a spacer of a compressor rotor assembly. The spacer teeth, in connection with the teeth or keys of the cross key ring can prevent rotation between the spacer and compressor disk. This is particularly beneficial during transient operations, such as startup and shutdown of the gas turbine engine.

Abstract: A gas turbine engine system includes a gas turbine engine and a control system including sensors for monitoring operating properties of the engine, a signaling device that outputs a discrete switching signal indicative of an engine load change, such as connecting or disconnecting an electrical load in an electrical power system powered by the gas turbine engine, and an electronic control unit. The control unit calculates an engine load estimate based upon the switching signal, the operating properties, and statistical information in a recursive statistical estimator.

Abstract: Systems and method for operating a gas compressor are disclosed herein. A compressor can have one or more dry gas seals surrounding the central axle of the compressor. The dry gas seals can each be pressurized with a barrier gas or other fluid supply providing a barrier within the dry gas seal. The method can include controlling delivery of a first barrier gas to the one or more dry seals during a startup or initiation of the compressor. The method can include controlling delivery of a second barrier gas different from the first barrier gas to the one or more dry seals based on the information received from sensors disposed within the compressor that can measure, inter alia, dry seal temperature and pressure within the system. The method can further include terminating the delivery of the first barrier gas based on the sensor information.

Abstract: A center body assembly for a lean direct injection fuel injector is disclosed. The center body assembly defines a primary liquid passage, a liquid gallery, a liquid main first passage, a liquid main second passage, and an atomizer assembly. The primary liquid passage supplies liquid fuel to the liquid gallery. The liquid gallery aligns with the primary liquid passage and distributes fuel to the liquid main first passage, and subsequently to the liquid main second passage. The atomizer assembly is in flow communication with the liquid main second passage and provides atomized fuel for combustion.

Abstract: A fuel injector for a combustor of a gas turbine engine is disclosed herein. In embodiments, the fuel injector includes an injector head adjoining a stem. The injector head includes a main premix passage, a main air inlet, vanes, and a main premix resonator. The main premix passage extends through the injector head and the main air inlet directs compressed air into the main premix passage. The vanes are located within the main premix passage for swirling the compressed air. The main premix resonator is located adjacent to and downstream of the vanes.

Abstract: A fuel injector for a combustion engine includes an injector head including a nozzle, a premixer, and a distributor structured to distribute a plurality of different fuels to different sets of fueling orifices in the premixer. A pilot assembly of the fuel injector is coupled to the premixer and includes a first fueling passage for a first fuel and a second fueling passage for a second fuel. Multiple sets of fueling orifices are positioned within the fuel injector, the fueling orifice sets being selectively connectable to a plurality of different fuel supplies, and both located and sized so as to accommodate a wide range of flow rates to enable a combustion engine coupled with the fuel injector to operate on fuels having a range of Wobbe numbers and compositions.

Abstract: A sump tank for use with a gas turbine engine in offshore conditions is disclosed. In embodiments, the sump tank includes two circuitous lubricant flow paths. Each flow path includes an end compartment, a side compartment, and a tube that feed to a central compartment. The baffles used to form the central compartment are angled so as to cause the lubricant entering from the tubes to swirl, which may increase the residence time of the lubricant and may help ensure that any entrained air is released from the lubricant prior to entering the suction line.
