Abstract:
A rotorcraft includes a body, a rotor blade, and a power train coupled to the body and operable to rotate the rotor blade. The power train includes an engine, a gearbox in mechanical communication with the engine, and a driveshaft in mechanical communication with the gearbox. The rotorcraft also includes a sensor operable to detect a rotorcraft parameter, and a lubrication flow calculation unit operable to receive the rotorcraft parameter, generate the flow rate based on the rotorcraft parameter, and transmit the flow rate to a lubrication system configured to deliver lubricant to the gearbox at the transmitted flow rate.
