Abstract: A starter can be configured for use with a turbomachine and includes a housing defining a cavity, wherein the cavity is configured to hold a quantity of starter oil, and a temperature sensor disposed within the cavity and configured to sense a temperature within the housing. A system includes a starter for a turbomachine as described herein and a computing apparatus configured to receive signals from the temperature sensor and to determine if the temperature within the housing indicates a sufficient quantity of starter oil. A method for determining oil quantity in a starter includes receiving a temperature signal from a temperature sensor disposed within the starter, determining an oil temperature within the starter based on comparing the temperature signal, and determining if a sufficient amount of oil is present in the starter based on comparing predetermined temperature operational values to the oil temperature.

Abstract: A starter supplemental lubrication system for a gas turbine engine is provided. The starter supplemental lubrication system includes a pneumatic starter operable to drive rotation of a rotor shaft of a gas turbine engine through an accessory gearbox. The pneumatic starter is configured to receive a primary lubricant flow at a first rotational speed range and receive a supplemental lubricant flow at a second rotational speed range that is less than the first rotational speed range. The starter supplemental lubrication system also includes a supplemental lubricant pump operable to supply the supplemental lubricant flow at the second rotational speed range. The supplemental lubricant pump is internal to the pneumatic starter.
