The engine assembly includes an oil pump configured to provide oil to an oil system of the engine assembly; a piston cooling jet configured to direct a jet of oil from the oil system towards a piston of an engine; and an electronic control valve configured to control the flow of oil to the piston cooling jet. The method includes operating the electronic control valve to provide a flow rate of oil above a threshold flow rate to the piston cooling jet when the engine assembly is operating above a threshold power output or engine running speed; and regulating the pressure of oil within the oil system when the engine assembly is operating below the threshold power output or engine running speed, by operating the electronic control valve.

There is described herein methods and system for correcting steady state errors in propeller speed by calculating a leakage flow rate as a function of engine and propeller parameters.

A cartridge injector cooperates with internal features of a manifold to form a complete injector assembly. The cartridge injector includes a poppet that translates within a central passage of an injector body to distribute fluid between an inlet region and an outlet region of the central passage. A piston reciprocates relative to the injector body, blocking and unblocking the inlet region, or outlet region, of the central passage to meter a volume of fluid delivered to an outlet of the manifold.

The invention relates to a lubrication device for a turbine engine, comprising an oil intake pipe (23) provided with a pump (24) for supplying oil and control means (25) located downstream from the supply pump (24), a supply pipe (26) intended for supplying oil to a member to be lubricated and a recirculation pipe (27), the control means (25) making it possible to direct all or part of the flow of oil from the intake pipe (23) towards the supply pipe (26) and/or towards the recirculation pipe (27), the pump (24) being driven by at least one rotary member of an accessory gearbox of the turbine engine.

A method of real-time oil consumption is disclosed. A method of real-time oil consumption detection may comprise capturing a raw oil quantity, calculating a corrected oil quantity, calculating a predicted oil quantity, calculating a prediction error, and calculating an estimated oil consumption rate. Raw oil quantity may be captured from an oil quantity sensor in an engine. Corrected oil quantity may be calculated by taking raw oil quantity and applying environmental and engine operational conditions. Prediction error may be calculated by finding the difference between corrected oil quantity and predicted oil quantity. Oil consumption rate may be calculated by applying a regression algorithm to prediction error.

An electronically driven lubrication system including an electric lubrication pump; at least one bearing for a gas turbine engine component; an oil cooler fluidly coupled with the electric lubrication pump; lubrication oil fluidly coupled with the electric lubrication pump, at least one bearing and oil cooler; at least one sensor in operative communication with the lubrication oil; a controller comprising a processor in operative communication with the at least one sensor, the electric lubrication pump, the at least one bearing and the oil cooler; and the processor configured to provide processor outputs to the electric lubrication pump responsive to data collected from the at least one sensor, wherein the processor employs an operational configuration for the electronically driven lubrication system.

A lubricant delivery system and method includes a valve manifold, an electronic controller, and a pressure sensor for determining whether there is adequate lubricant flow in the system. The valve manifold receives lubricant from a pressurized source. The valve manifold includes a plurality of valves configured to control the flow of lubricant to respective applicators. The electronic controller controls the opening and closing of the valves. The pressure sensor measures lubricant pressure in the valve manifold, and outputs a signal to the electronic controller. The signal correlates to a lubricant pressure value in the valve manifold. The electronic controller uses the lubricant pressure values to derive an indication of lubricant flow (via the valves) to the applicators.
