An organometallic chemistry-based compound for preventing coke formation in a hydrocarbon fluid system. The organometallic chemistry-based compound includes a coordination complex that interrupts an autoxidative pathway of coke formation. A component and a system for mitigating coke formation during delivery or circulation of a hydrocarbon fluid. The component includes a contact surface configured to be in contact with the hydrocarbon fluid. The contact surface is functionalized with an inhibitor ligand to form an inhibitor ligand-functionalized surface. The inhibitor ligand-functionalized surface interrupts an autoxidative pathway of coke formation.

A method of distributing oil to a component within a gas turbine engine includes directing a first oil flow from an oil source to an engine component and back to the oil source, directing a second oil flow from the oil source to a generator driven by the engine and back to the oil source, monitoring a parameter of the second oil flow downstream of the generator and upstream of the oil source, detecting a contaminant in the second oil flow based on the parameter, and reducing the second oil flow to the generator when the contaminant is detected without reducing the first oil flow to the engine component. A shared oil system for a component of a gas turbine engine and a generator driven by the gas turbine engine is also discussed.

Disclosed is a sump cover for a sump basin of a generator of an aircraft, the sump cover having: a sump cover shell shaped as an inverted bowl, a front portion of the sump cover shell including a first plurality of fastener features, each configured to fasten to one of a second plurality of fastener features in the sump basin; and a sump cover support extending outwardly from the sump cover shell, past a perimeter edge of the sump cover shell, configured to fit through a sump port and against a sump tube of the sump basin, wherein the sump cover support and the first plurality of fastener features define a multi-point mounting configuration between the sump cover and the sump basin.

The present invention relates to a device (100) for supplying fluid to an electric drive train for a motor vehicle, preferably for cooling and lubricating a transmission (50) and/or for supplying oil to an electric motor of the electric drive train. The device (100) comprises a main pump (10) configured as a hydraulic fixed displacement pump for delivering fluid from a fluid reservoir (40) to the electric drive train. The apparatus (100) further comprises at least one auxiliary pump (20) configured as a hydraulic fixed displacement pump. The main pump (10) and the auxiliary pump (20) are mechanically driven by the transmission (50) of the electric drive train in such a way that a fixed transmission ratio exists between a pumping rotation speed of the main pump (10) and a pumping rotation speed of the auxiliary pump (20), wherein the auxiliary pump (20) can be selectively connected by means of a controllable actuating device (30) for supplying fluid to the electric drive train.
