Abstract

Systems (100) and methods are provided for calibrating a hydraulic starter (50) for a turbomachine (10). A hydraulic fluid source (54) supplies fluid at a high pressure or at a low pressure for rotatably driving the hydraulic starter, and a valve (64) is movable to adjust a flow rate of the fluid supplied from the hydraulic fluid source to the hydraulic starter. The hydraulic fluid source and operation of the valve are automatically controlled by a computing system (102) to sequentially perform a plurality of base modes with the valve (64) being in either a fully closed position or a fully opened position. The plurality of base modes includes at least one standby mode test and at least one crank speed mode test. A rotational speed of the turbomachine detected by a speed sensor (66) during each of the plurality of base modes is monitored by the computing system for calibrating the hydraulic starter.
